Connecting DC Power

To connect a high or low DC power supply to the device, do the following:

Electrical hazard – risk of damage to equipment

Before testing the dielectric strength (HIPOT) in the field, remove the braided

ground cable connected to the surge ground terminal and chassis ground. This cable

connects transient suppression circuitry to chassis ground and must be removed in

order to avoid damage to transient suppression circuitry during testing.

Using a #6 ring lug and #6-32 screw, secure the ground terminal on the power

source to the chassis ground terminal on the device. Make sure the lug is

tightened to 1.7 N·m (15 lbf·in).
