Warning – Meltric SPeX User Manual

1 Insert the plug straight into the receptacle, until a

‘click’ is heard. NOTICE: The plug and its flexible

cable must not exert constraint on the receptacle.

2 Pull on the plug to make sure it is properly

latched in the receptacle. A small rotation of the plug,

in either direction, allows the locking finger of the

receptacle to prevent any further rotation.

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.

MAINTENANCE

Before inspecting, repairing, or

maintaining Meltric products, dis-

connect electrical power to the receptacle to eliminate

the risk of electrical shock. Rules applying to products

for use in explosive atmospheres impose that any re-

placement of component 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 contact surfaces for cleanliness

and pitting.

Use a clean cloth to rub off deposits of dust or similar

foreign materials on the contacts and the plug interiors.

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

If any significant pitting of the contacts or other serious

damage is observed, the device should be replaced.

Any repair or service must be achieved with genuine

parts only.
