All load cables, including the neutral (if used), should pass
through the window of the sensor.
All wiring to the GFR-2 Ground Relay System should be rated 600V.
Use a minimum of number 14 AWG. Ensure that safety requirements
are met as per your local electrical code.
The conductors from the Sensor to the GFR-2 Relay carry very low
current. Extra care should be taken to keep this wiring at least
10 cm away from the power conductors. The wiring should be set
up as a twisted pair and grounded at one point only. If the length
of wiring exceeds 1.5 m, the twisted pair should be shielded and
grounded as shown below.
connections are shown in Fig 2, 3 and 4, below.
