• One ground terminal is factory-wired to the
ground contact. This wire must not be removed
as it also grounds the second and third ground
terminals.
• Second ground terminal is used for the
ground conductor.
• Third ground terminal is used to ground the
accessory (box, handle, angle).
COLOR CODED GASKETS
Insert the color-coded gaskets between the device
and its rear accessory (box, handle, angle).
The two protrusions on the gasket must be
positioned on the latch sides of the receptacle/
connector and on the catch side for the inlet/plug.
This gasket is needed to maintain the IP rating.
If used in conjunction with finger draw plates, the
gasket must be between the receptacle (or inlet).

• Only devices with compatible contact
configurations and electrical ratings will
mate with each other.
• The receptacle is shielded by a protective
lid held in the closed position by two latches.
Depress the latches to release the lid.
• To connect, align the arrow heads on the
housings (see Figure F4), insert the device
and turn it clockwise until it hits a stop. The
device is in the rest position and the circuit
remains open.

• Push the device straight into the complementary
device until it becomes securely latched.
• To disconnect, depress the latching pawls
simultaneously. The device returns to its rest
position and the circuit is open.
• To remove the device, turn it counter-clockwise
and pull. Replace receptacle lid.
CONNECTION LOCKING (OPTION)
With the plug fully mated to the receptacle, insert the
metal locking pin through the hole in the pawl on the
receptacle and place a padlock or other locking
device through one of the holes on locking pin.
This will prevent unintended disconnection.
PLUG LOCKOUT (OPTION)
• To prevent the plug from being inserted
into a receptacle, place a padlock or other
lockout device through the hole provided
in the plug casing.
MAINTENANCE
• IEC/EN 60079-17 & UL 60079-17standard:
Explosive atmospheres – Part 17: "Electrical
installations inspection and maintenance",
foresees very strict requirements regarding
the maintenance of electric installations which
must be imperatively respected.
• Ensure that the fixing screws, caps and cable
glands are tight.
• Verify that the weight of the cable is supported
by the strain relief mechanism and not by the
3
terminal connections.

• Check the cleanliness of contacts.
• To inspect the contacts, depress the springloaded
ejection ring on two opposite points. The safety
shutter can then be rotated clockwise to inspect
contact tips.
• Any deposit can be rubbed off with a clean
cloth or compressed air.
• In case of damage, contact your supplier to
have them replaced by the manufacturer.
• Do not forget to re-lock the safety shutter
after inspection.
• Inspect periodically IP gaskets for wear and
resilience. Replace as required.
• Check regularly the continuity of the ground
circuit by electric tests.
