GENERAL

Meltric’s DX Series plugs & receptacles are designed

for industrial use according to IEC/EN 60309-1. They

are designed for applications where rugged metal

construction is required and when there is a need for

amperages up to 100A. Follow the instructions below

to ensure the proper installation and use of this product.

There are inherent

dangers associated

with electrical products. Failure to follow safety pre-

cautions can result in serious injury or death. These

instructions must be followed to ensure the safe and

proper installation, operation and maintenance of the

Meltric devices. Before installation, disconnect all

sources of power to the circuit to eliminate the risk

of electrical shock.

RATINGS & CERTIFICATIONS

To ensure the safe use of this product,

the installer must verify that the product

is properly rated for the application.

The amperage, voltage, temperature, and environ-

mental ratings are indicated on the product label.

Meltric’s DX Series plugs and receptacles are

ATEX-rated in accordance with the European ATEX

Directive (94/9/EC).

The ATEX rating certies the product for use in surface

(non-underground) applications where a high level of

protection is required and where the presence of an

explosive atmosphere is likely to occur (Zone 1 and

Zone 21 environments). It’s suitable for installation in

areas that may contain ammable gases, vapors, mists,

or dusts, including subdivision C gases. The prod-

uct possesses explosion protection and is provided

with ‘e’ increased safety in the conductor termination

area and ‘d’ explosion proof chambers for making

and breaking electrical current that can withstand the

pressure of internal ignition. It also can prevent arcs,

ame or other ignition events from being communi-

cated to the surrounding atmosphere. The maximum

allowable surface temperature of the product is 85°C

(185°F) at 40°C (104°F) ambient.

INSTALLATION

DX Series devices must be used in conjunction

with other appropriately rated hazardous duty

products and must be installed by qualied electri-

cians and in accordance with all applicable local and

national electrical codes.

Before installing, verify that (1) the power is off, (2)

the product ratings are appropriate for the application,

and (3) the conductors meet the requirements of the

National Electric Code and are within the capacities of

the DX terminals noted in Table 1.

General Installation Notes & Precautions

1. Wire strip lengths are indicated in Table 2. Strip

lengths for cable sheathing will depend on the

specic application. When used with handles, the

cable sheathing should extend into the handle to

ensure secure cord gripping.

2. Wiring terminals are spring assisted to prevent

loosening due to wire strand settlement, vibration

and thermal cycling. NOTICE: They should not

be overtightened. Appropriate tools and tightening

torques are indicated in Table 3. Wiring must be

made according to applicable national installation

standards. Follow all conductor coding and terminal

marking standards. Back out terminal screws far

enough (but not completely) to allow a complete

insertion of conductors. All metal parts

must be connected to Earth ground.

Other sizes can be used with the help of wiring ferrules.

3. Only handles with supplied cord grips may be

used in order to maintain proper ATEX ratings.

Assembly for In-line Plugs/Connectors

Do not overtighten terminal or self-tapping

screws. Tighten screws to the proper torque to

ensure a secure connection.

Insert cable through handle (connector) or remove

plug interior molding from the front and insert cable

through plug body (plug/inlet). Strip the cable sheath

as required to provide a workable wire length while

being aware that the strain relief must clamp on the

cable sheath. Strip the individual wires to the lengths

indicated in Table 2 and twist the strands of each

conductor together. Back out the terminal screws on

the receptacle (or inlet) only far enough to allow the

conductors to pass. Insert the conductors fully into

their respective terminals and tighten the terminal screws

with a hand screwdriver to the torque indicated in Table

3. Verify that the cable jacket will extend beyond the

strain relief and into the handle. Assemble the recep-

tacle (or connector) to the handle. Adjust the cable

location so that it will not be under tension inside the

handle and tighten the compression nut to secure the

cable. After assembly, the cable sheath must extend

into the handle. Assemble handle with supplied

screws and gasket (connector) or assemble interior

molding into plug casing (plug) and tighten cord grip

(cable gland). Cord grip cable tightening ranges are

indicated in Table 4. While clamping or anchoring,

the conductors inside the handle must not be tight.

NOTICE: For a proper clamping the use of PVC

cables is not recommended.

Assembly for Mounted Receptacles (or Inlets)

In applications where DX receptacles are mounted

to wall boxes, panels or other equipment, optimal

operation is achieved when the device is installed with

the pawl latch at the top. (However, if the receptacle

is mounted to the Meltric surface box accessory, the

pawl latch will be on the bottom due to the vertical

orientation of the box/receptacle.)

NOTICE: if the DX device is mounted to a wall box,

make sure that hole plugs are securely tightened in

any unused connection holes.

All wires brought into a Meltric wall box or hazardous

duty box/panel must be connected in accordance with

all approved local and national electrical codes based

on the rating of the hazardous location environment.

The individual wire insulators should be stripped off

base on the dimensions given in Table 2. Then, twist

the strands of each conductor together. Back out the

terminal screws on the receptacle (or inlet) far enough

to allow the conductors to pass and insert the con-

ductors fully into their respective terminals. Tighten

the terminal screws with a hand screwdriver to the

torque indicated in Table 3. Assemble the receptacle

(or inlet) on adapter or wall box, using gaskets and

screws provided. When not in use, ensure that the

protective cap or lid supplied is properly secured to

prevent environmental contamination. Assemble the

mating plug (or inlet) to the cord end as indicated in

the assembly instructions for in-line connections. In

cases where custom mounting is being performed to an

appropriate hazardous duty box or panel, the clearance

and mounting holes should be drilled as indicated in

the next section, Hole Pattern for Custom Mounting.

Hole Pattern for Custom Mounting

NOTICE: In order to maintain IP65 protection in cus-

tom installations, watertight seals must be used under

the heads of the four mounting bolts and they must

be retained by a lock washer and nut on the inside of

the box or panel. The hole depth must be sufcient to

achieve adequate gasket compression. Refer to the

following instructions and drawing for the assembly of

the plug/receptacles or inlets on ‘e’ increased safety

boxes, panels or enclosures:

OPERATION

To ensure a safe and reliable operation,

Meltric’s DX Series plugs & receptacles must

be used in accordance with their assigned

electrical and Ex ratings, as well as their IP

ratings according to IEC/EN 60309-1.

They can only be used in conjunction with mating

receptacles or plugs manufactured by Meltric or

another licensed producer of products bearing the

technology trademark.

Meltric plugs & receptacles are designed with different

keying arrangements so that only plugs and receptacles

with compatible contact congurations and electrical

ratings will mate with each other. When not in use,

the receptacle is shielded by a protective lid to prevent

the entry of dust and moisture. This is held in the

closed position by a latch.

Connection

To connect a plug and receptacle, rst depress the

pawl to release the lid on the receptacle, then orient

the plug so that the colored mark on the outside ridge

of the plug casing lines up with the Ø or unlock sym-

bol on the receptacle casing. Push the plug in par-

tially into the receptacle until it hits a stop Fig. 1. At

this point, the circuit is still open. To close the circuit,

turn the plug clockwise Fig. 2 until it hits another

stop after about 30° of rotation. Fig 3.

NOTICE: When making a connection, ensure that

the plug latch is secured behind the catch on the blue

pawl. A properly connected plug cannot be pulled out

of the receptacle.

Disconnection

To break the connection, depress the pawl and rotate

the plug counterclockwise about 30° until it hits a

stop. At this point, the electrical circuit is open. To

fully remove the plug, depress the pawl and pull the

device straight out. The self-closing lids on the re-

ceptacles may need to be manually latched to ensure

optimal environmental ratings.

Achieving Rated Watertightness

Meltric’s DX Series plugs & receptacles have an IP65

rating for protection against ingress of water, dust and

other matter. IP65 provides total protection against

dust and water jets. These ratings apply when the

plug and receptacle are mated. They also apply to

the receptacle alone, provided that its lid is latched in

the closed position. Optional plug caps are available

for providing IP65 protection on unmated plugs.

LOCKOUT PROVISIONS

All DX plugs are provided with two types of lockout

provisions: hexagonal screw locking and padlocking

provisions. For hexagonal screw locking with the

plug inserted or lid closed (plug not in use), turn the

hexagonal screw with a key until it reaches the bot-

tom. Do not over tighten. For padlocking, insert the 3

hole shaft through the hole under the receptacle pawl.

Place user supplied lock or lockout hasp through one

of the holes. This system may be used to lock mated

devices together to prevent unintended disconnection

or to prevent mating of devices by locking the recep-

tacle lid closed.

NOTICE: Attaching the receptacle locking device with

the lid open will not prevent the insertion of a plug.

Lockout is only accomplished when the lid is locked

closed.

MAINTENANCE

Before inspecting, repairing,

or maintaining Meltric prod-

ucts, disconnect electrical power to the receptacle to

eliminate the risk of electrical shock. Any replacement

of DX components must be performed under the

control of the manufacturer: Meltric Corporation.

Meltric products require little on-going maintenance.

However, it is a good practice to periodically perform

the following general inspections:

• Check the mounting screws for tightness.

• Verify that the weight of the cable is supported

by the strain relief mechanism and not by the

terminal connections.

• Check the IP gaskets for wear and resiliency.

Replace as required.

• Verify the electrical continuity of the ground circuit.

• Check the inlet contact surfaces for cleanliness

and pitting.

Deposits of dust or similar foreign materials can be

rubbed off the contacts with a clean cloth. Sprays

should not be used, as they tend to collect dirt. If

any signicant pitting of the contacts or other serious

damage is observed, the device should be replaced.

DECLARATION OF CONFORMITY
