The supply of the pilot circuit must be protected
against transient over-voltages of 4 kV by means of an

appropriate isolating device. Follow the requirements
set forth by the ATEx classication. DO NOT ATTEMPT
TO TURN THE RING TOWARDS ‘‘1’’ WHEN THE
PLUG IS NOT ENGAGED.

Electrical interlocking with a contactor is mandatory.

Assembly

Insert cable through the cable gland and the handle or
through the inclined sleeve.

Wiring of the pilot wires

Use exible conductors with a cross-sectional area
between 0.5 and 1 mm

NOTICE: These conductors must be connected to the

wires of the microswitch by means of the isolated crimping
lugs supplied. Use an appropriate crimping tool.

A typical pilot circuit wiring diagram is shown below.

Assembly of the metal inclined sleeve.

Maintain air and creepage distances when assembling

the appliance inlet or the receptacle onto the metal
inclined sleeve, according to the operating voltage of
the main and auxiliary circuit and the degree of pollution.

The metal inclined sleeve must be grounded
to Earth.

Assembly of the plug/inlet cap

Place the lug located at the tip of the wire under one
of the mounting screws on the inlet side, or under the
screw provided under the receptacle side.

Color-coded rings

In order to achieve watertightness, do not forget the

color-coded ring at the rear of the inlet or receptacle.

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 Directive 2014/34/UE. 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 tted 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 nger (IP2x/IPxxB) according to IEC/EN 60529

standard.

There are inherent dangers

ducts. 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 qualied person in
accordance with all applicable local and national

electric codes. Be sure power is off before starting.

Wiring of the main conductor

Wire the main conductors within the amperage

and hazardous duty requirements of the ATEX

(T5) classication. The cross-section must be at least
that dened in the certicate 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 gland with an appropriate tool. To achieve the
IP65/IP66 of an interlocked connector, use a cable that
incorporates the two pilot wires that are required for the
interlock, or use an ATEX cable gland bushing that allows
the passage of the main cable and the two pilot cables.

The silicone ring must be assembled on the receptacle
ring.

Color-coded ring

The color-coded rings allows visual identication of

the pole depending on the color code of each country.
Place the color coded gasket between the inlet or
receptacle and its rear accessory or panel.

Isolating ring

Flat gasket Isolating ring

Color-coded ring

When assembling the SPeX on a metallic support

(enclosure, panel, etc.), the isolating ring must be

positioned as above. Be sure to use the black at
gasket, which guarantees the watertightness, between

the isolating ring and the accessory.

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 nger.

OPERATION

To ensure safe and reliable operation, MELTRIC

plugs and receptacles must be used in accordance

with their assigned ratings.

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.

MANUFACTURER’S RESPONSIBILITY

disconnect electrical power to the receptacle to eliminate
the risk of electrical shock. Rules applying to products
for use in explosive atmospheres impose that any
replacement of component must be performed under

the control of the manufacturer: MELTRIC Corporation.

MELTRIC’s responsibility is strictly limited to the

repair or replacement of any product that does not

contract. MELTRIC shall not be liable for any

penalties or consequential damages associated with
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 contact surfaces for cleanliness

3 To close the pilot circuit, turn the ring of the receptacle
up to the stop towards “1”.

Check the continuity of the pilot.

Do not attempt to turn the ring toward “1” when

there is no plug engaged. Defeating the mechanical
lock could create a potentially hazardous or explosive
condition if energized under load.

4 To open the pilot circuit and unlock the plug, turn
the ring back to “0” up to the stop. Press on the
button to release the plug. The caps must then be
re-assembled on both sides.
