Section 2.4.1
Connecting AC Power
To connect a high AC power supply to the device, do the following:
CAUTION!
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.
1. Connect the positive wire from the power source to the positive/hot (+/H) terminal on the terminal block.
