GENERAL
The SPeX is a single-pole plug and receptacle for use
in explosive atmospheres and conforms to the relevant
international and European standards, particularly the
ATEX 94/9/EC Directive. SPeX can be used in zones
1 and 2 (gas) and 21 and 22 (dust).
In order to guarantee a connection and disconnection in
complete safety, the SPeX receptacle is fitted with an
electromechanical device (switch + ring) for electrical
interlocking with a contactor (breaker) and an integral
pilot control circuit.
Receptacle contacts are protected against standard
test finger (IP2X) according to IEC/EN 60529 standard.
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
SPeX devices are provided with optional auxiliary
contacts that make after and break before the phase
contacts. The ratings for auxiliary contacts are shown
in Table 1.
INSTALLATION
SPeX must be installed by a qualified electrician
in accordance with all applicable local and
national electric codes. Be sure power is off before
starting.
T
he supply of the pilot circuit must be protected against
t
ransient over-voltages of 4 kV by means of an
a
ppropriate isolating device.
Electrical interlocking with a contactor is mandatory.
Assembly
I
nsert cable through the cable gland and the handle or
t
hrough the inclined sleeve.
W
iring of the pilot wires
Use flexible conductors with a cross-sectional area
b
etween 0.5 and 1 mm
2
(
16 to 20 AWG).
NOTICE: These conductors must be connected to the
w
ires of the microswitch by means of the isolated
c
rimping lugs supplied. Use an appropriate crimping
tool.
Wiring of the pilot contacts
T
he prewired pilot contact leads should be connected to
t
he power control circuit with the ferrules provided. The
blue ferrules should be used for 14 AWG (1.5 - 2.5 mm)
f
lexible wire and the yellow ferrules for 12 AWG (4 mm)
flexible wire. Strip the wires to expose 0.30 in (8 mm)
of the conductors, insert both wires into the ferrule and
c
rimp with an appropriate tool.
A
typical pilot circuit wiring diagram is shown below.
Wiring of the main conductor
Wire the main conductors within the amperage
and hazardous duty requirements of the ATEX
(T5) classification. The cross-section must be at
least that defined in the certificate or the CE Declaration
of Conformity, depending on the maximum current.
Strip the conductor by 1.8” (46 mm). Crimp the
threaded lug or the ferrule with the appropriate die
(NFC 20-130 or VDE 0220 or another). Hexagonal
crimping is recommended.
Tighten the threaded lug with a 24 mm wrench or
tighten the ferrule with a screw and a washer with a 19
mm wrench. Apply a torque ca. 95 ft-lbs (70 N.m).
While tightening the ferrule, prevent the contact from
rotating or transmitting torque to the device with a 24
mm wrench.
Assembly of the connector
Assemble the handles on the body of the products with
the supplied gaskets and screws and tighten the cable
g
land with an appropriate tool. To achieve the IP65/IP66
o
f an interlocked connector, use a cable that incorporates
t
he two pilot wires that are required for the interlock, or
u
se an ATEX cable gland bushing that allows the
passage of the main cable and the two pilot cables.
T
he silicone ring must be assembled on the receptacle ring.

the appliance inlet or the receptacle onto the metal
i
nclined sleeve, according to the operating voltage of
the main and auxiliary circuit and the degree of pollution.
The metal inclined sleeve must be grounded

A
ssembly of the plug/inlet cap
A
ssemble the small fixing part supplied on the last
link of the chain and fix it to the plug/inlet body by
m

C
olor-coded rings
In order to achieve watertightness, do not forget the
c
olor-coded ring at the rear of the inlet or receptacle.
The color-coded rings allows visual identification of the
pole depending on the color code of each country.
Isolating ring
When assembling the SPeX on a metallic support
(enclosure, panel, etc.), the isolating ring must be
positioned as above.
Receptacles, plugs, connectors and inlets are protected
against dust and water ingress by means of caps, which
must be re-assembled after use.
To achieve IP65/IP66, the receptacle or connector cap
must be assembled with its slot facing the socket-outlet
protruding finger.
OPERATION
To ensure safe and reliable operation, Meltric
plugs and receptacles must be used in accor-
dance with their assigned ratings.
They can only be used in conjunction with mating re-
ceptacles or plugs manufactured by Meltric or another
licensed producer of products bearing the
TM
technology trademark.
