Exp Cord Cap
Position device near work area for operation. Run cable to nearby power
source. Insert and twist-lock explosion-proof plug into a compatible receptacle within
the hazardous environment. See
plug operation
below.
PLUG OPERATION
Electrical connection between plug and compatible receptacle is accomplished
after plug fully inserts into receptacle and rotated clockwise.
1.
Lift receptacle door and locate polarization on mating plug pin and
receptacle face. Insert plug straight all the way into receptacle until it
cannot go further.
2.
Rotate plug clockwise limit (37º), this closes internal contacts and
completes circuit. This also mechanically locks plug into receptacle so it
cannot be pulled out.
3.
To remove plug, push plug inward and turn to counterclockwise, pull plug
straight out.
GROUND-FAULT CIRCUIT INTERRUPTER (GFCI)
In the event of a ground fault, a GFCI will trip and quickly stop the flow of electricity to prevent serious injury.
Definition of a ground fault:
Instead of following its normal safe path, electricity passes through a person's body to reach the ground. For example, a
defective appliance can cause a ground fault.
A GFCI receptacle does
NOT
protect against circuit overloads, short circuits, or shocks. For example, you can still be
shocked if you touch bare wires while standing on a non-conducting surface, such as a wood floor.
NOTE:
GFCI's contain a lockout feature that will prevent RESET if:
• There is no power being supplied to the GFCI.
• The GFCI is miswired due to reversal of the LINE and LOAD leads.
• The GFCI cannot pass its internal test, indicating that it may not be able to provide protection in the event of a ground
fault.
GFCI TEST
Use an approved GFCI tester or plug an electrical device, such as a lamp into the receptacle on which you are working.
Turn the lamp or device ON. Then, press the TEST button on the GFCI box and power should immediately be switched
off. If not, contact an electrician. Press the RESET button to restore power.
INTER-COMPATIBILITY
These cords use T style plugs and will work with non-explosion proof standard receptacles and plugs (NEMA 5-15R,
5-20R, or 6-20R) but will not work with standard 120V wall outlets. The included plug is cross-interchangeable with
Crouse Hind™ part# ENP5201 plugs and receptacles and Hubble-Killiark part# UGP-20231 ACCEPTOR® plugs and
receptacles. Any equipment requiring these C-H or H-B plugs should work with these cords. Due to possible
manufacturer changes we cannot guarantee interchangeability although we have made every effort to ensure cross
compatibility correctness.
MAINTENANCE
There are no serviceable parts inside the fixture. However, it is good practice to routinely clean and check the
fixture for proper function.
•
Disconnect power running to the
unit
and be sure the fixture is cool to the touch.
•
Use a non-abrasive glass cleaning solution to clean the lens.
