GG-2

Wiring

•  Electrical wiring must comply with all applicable codes.

Wiring Guidelines:

• 

Use stranded, copper wire/cable with a minimum of 75°C rating (167°F).

•  Always use three-conductor, insulated, stranded, shielded copper cable 

for all sensor cables.

•  Do not pull sensor wiring with AC power cables. This can cause electrical 

interference.

•  Be sure to land the shield conductors of the sensor cables at the shield 

terminals of the sensor connectors.

•  Use only the existing conduit hole for connections to the sensor.
•  Bonding between metallic conduit connections is not automatic with the 

non-conductive enclosure. Separate bonding must be provided.

•  During installation, cover conduit holes and close the enclosure cover to 

prevent debris from falling into the equipment.

• 

To maintain NEMA 4X / IP 66 rating of the enclosure, conduit fittings of the 

same rating or better must be used.

AC Power Wiring:

•  Power should be provided by a dedicated 15A circuit breaker. It is 

recommended that the circuit breaker be located near the equipment, 

and clearly marked as the disconnect for the GG-6 controller.

•  100-240 VAC, 1.3 A, 50/60 HZ

Relay Wiring:

•  AC wiring must be run in separate conduit from the sensor cables.
•  All relays have Form C dry contacts, and are rated 8 Amps @ 24 VDC or 10 

@ 240 VAC (dry contacts require external power).

•  Only the fault relay is normally energized. It will de-energize to the alarm 

state upon sensor fault or loss of power.

•  Each relay has a status LED to show the state of the relay. During normal 

operation, all LEDs are off except for the green Fault LED.
