3.
When the grounding clamp is connected to a dispensing or
receiving vessel and the ground circuit is completed, auxiliary
contacts between terminal block positions 4 & 6 and 7 & 9 will
be OPEN. Contacts between terminal block positions 4 & 5 and
7 & 8 will be CLOSED. Remote signals connected between
terminal block positions 4 & 5 and 7 & 8 will indicate completion
of the grounding circuit. Signals connected between terminal
block 4 & 6 and 7 & 9 will indicate interruption of the grounding
circuit.
The ground connector clamp must be attached to a metal surface
which is clean and free of rust, dirt, paint or other insulating films
or finishes. THE CLAMP MUST BE ATTACHED TO THE
TANKER OR OTHER DEVICE WHICH IS DISPENSING OR
RECEIVING THE COMBUSTIBLE MATERIAL. DO NOT PLACE
ANY OTHER METAL BETWEEN THE CLAMP'S JAW SINCE
THIS WOULD DEFEAT THE GROUND VERIFICATION
SYSTEM. Failure to follow these instructions could result in an
EXPLOSION !
EGL housing must be grounded. DO NOT USE OTHER
MEANS TO DEFEAT THE NEED TO RUN AN ADDITIONAL
GROUND LEAD. The two ground leads should be connected
back at the electrical supply panel. If one of the ground leads is
damaged, broken or defective, turn OFF power and replace
immediately.
If green indicator light is on and clamp is not engaged with
conduction material, it is an unsafe condition. Verify that clamp
jaws are insulated and wiring is in accordance with Figure 2
wiring diagrams.
MAINTENANCE
Always disconnect primary power source before opening
enclosure for inspection or service.
1.
Frequent inspection should be made. The total grounding
indicator installation should be visually checked for physical
damage prior to each usage. A schedule for maintenance
checks should be governed by the environment and frequency
of use. It is recommended that it should be performed at least
once a year. We recommend an Electrical Preventative
Maintenance Program as described in the National Fire
Protection Association Bulletin NFPA 70B: Recommended
Practice for Electrical Equipment Maintenance (www.nfpa.org).
All statements, technical information and recommendations contained herein are based on information and tests we believe to be reliable. The accuracy or completeness

If any part of the grounding indicator or total installation
appears to be broken or damaged,
DISCONTINUE USE IMMEDIATELY.
Replace, or properly repair, the item before continuing use.
2.
Perform visual, electrical, and mechanical checks on all
components on a regular basis.
•
Visually check for undue heating evidenced by discoloration of
wires or other components, damaged or worn parts, or leakage
evidenced by water or corrosion in the interior.
•
Electrically check to make sure that all connections are clean
and tight.
•
Mechanically check that all parts are properly assembled.
•
Visually inspect ground path and connections for signs of
deterioration which could affect grounding continuity.
INSTALLATION OF EGL K1 REPLACEMENT
CLAMP ASSEMBLY
1.
Remove the old clamp assembly if applicable.
2.
Individually terminate each wire onto a ring terminal.
3.
Attach the ring terminal to the jaw assembly using the screw
provided. Repeat for the second ring terminal on the opposing
jaw assembly. Ensure that each ring terminal is not touching
the handle. A connection to the handle will create an electrical
short and give a false reading on the grounding indicator.
4.
Place the jacketed cable in the strain relief on the interior of the
handle assembly. Secure the cable by bending the strain relief
around the jacket.
