Meltric SP Series Manuel d'utilisateur télécharger pdf

GENERAL

SP devices are single-pole, high-amperage plugs and

receptacles that are designed for safety, durability,

and ease of operation. Each device is mechanically

interlocked with an integral pilot circuit switch for

controlling the power circuit in order to prevent

connection and disconnection under load. Each of

the phases as well as the neutral and ground, are

color coded and keyed to prevent improper connection.

SP receptacles are IP 2X rated to prevent accidental

finger contact with live parts.

There are inherent dangers

associated with electrical

products. Failure to follow safety precautions 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. This product must be installed with an

electrical interlock that prevents connection or

disconnection in a loaded condition.

RATINGS

The SP series is CSA listed for use in Non-Load

Break applications up to 600A at 600VAC, 500 HP 3

phase at 480 VAC and 600 VAC. The SP devices

are NOT designed or Listed for current interruption.

The SP receptacle is provided with two auxiliary/pilot

contacts that make (close) when the locking collar is

rotated after plug insertion. The pilot contacts are

designed for use in control circuit wiring of medium

current switchgear, (see diagram of pilot circuit

wiring). The SP pilots have a D300 rating as shown

in Table 1. The phase contact is rated to withstand a

30 kA short circuit with a current limiting fuse rating

as shown in Table 2. Consult Meltric Engineering for

horsepower ratings and limitations at lower voltages.

NSTALLATION

P devices should be installed by qualified

lectricians in accordance with all applicable

local and national electrical codes.

efore installing, verify the power is off and the prod-

ct ratings are appropriate for the application. Ensure

he conductors meet code requirements and are with-

in the wiring terminal capacities noted in Table 3.

NOTICE: Ensure the plug and its flexible cable do

ot exert a significant force or a constraint on the

eceptacle.

Wiring of the pilot contacts

The SP auxiliary/pilot contact leads of each device

should be wired in series within the power control

circuit. A typical pilot circuit wiring diagram is

shown below.

Wiring of the main conductor

Use a flexible cable between 2 /0 and 777 MCM (70

and 400 mm

). Strip the insulation as appropriate for

the lug being used. Solder lugs have integral threads

that screw into the terminals. The solder lug should

be tightened until the tapered section is secured in

solid contact with the terminal. Crimped lugs are

secured with M12 bolts that should be tightened to

approximately 30 ft-lb (40 N.m.) with a 3/4” (19 mm)

wrench.

NOTICE: To avoid transmitting torque to the device

moldings when securing the lugs, hold the terminal in

place with a 24 mm wrench (flats are provided).

ole Pattern for Custom Mounting

NOTICE: In order to maintain IP66/67 protection in

ustom installations, watertight seals must be used

nder the heads of the four mounting bolts and they

must be retained by a lock washer and nut on the

nside of the box or panel. Alternatively, four blind

holes can be drilled and threaded to accommodate

8-32 x 5/8” mounting screws. The hole depth must

e sufficient to achieve adequate gasket compression.

ttaching the handle

Insert cable through cable gland and handle before

ightening the phase conductor. Assemble handle

with the screws and gasket supplied, (use short

crews for inlets, long screws for receptacles) and

ighten cable gland with an appropriate tool.

NOTICE: Meltric solder lugs are required for use

with handles.

Attaching the metal angle (if required)

Attach receptacle or inlet to metal angle using the

screws and gasket supplied, (use short screws for

inlets, long screws for receptacles). Connect the

metal angle to ground.

Assembly of the plug /inlet cap

Attach the cap to the plug /inlet by retaining the end

of the chain under one of the mounting screws.

Gasket

In order to achieve rated watertightness, the flat

black gasket must be installed between the inlet or

receptacle and the panel or accessory to which it

is attached.

Rated current and voltage markings

It is essential to indicate the current and voltage of

the main circuit on the supplied stickers. Apply the

stickers on or adjacent to the product so they can

easily be seen.

OPERATION

To ensure safe and reliable operation, Meltric

plugs and receptacles must be used in

accordance with their assigned ratings.

SP devices can only be used in conjunction with mat-

ing receptacles or plugs manufactured by Meltric or

another licensed producer of products bearing the

technology trademark.
