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 and 6, and 7 and 9 will be OPEN. Contacts between terminal block positions 4

and 5, and 7 and 8 will be CLOSED. Remote signals connected between terminal

block positions 4 and 5, and 7 and 8 will indicate completion of the grounding

circuit. Signals connected between terminal block 4 and 6, and 7 and 9 will indicate

interruption of the grounding circuit.

! WARNING

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!

! WARNING

EGL housing must be grounded. DO NOT USE OTHER MEANS TO DEFEAT

THE NEED TO RUN AN ADDITIONAL GROUND LEAD. The two (2) 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.

! CAUTION

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

! WARNING

Always disconnect primary power source before opening enclosure for inspection

or service.

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).

! WARNING

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.

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

Remove the old clamp assembly, if applicable.

Individually terminate each wire onto a ring terminal.

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.

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.
