1. Positive/Live (+/L) Terminal
2.
Connect the negative wire from the power source to the negative/neutral (-/N) terminal on the terminal block.
3.
Using a braided wire or other appropriate grounding wire, connect the surge ground terminal to the chassis
ground connection. The surge ground terminal is used as the ground conductor for all surge and transient
suppression circuitry internal to the unit.
4.
Connect the ground terminal on the power source to the chassis ground terminal on the device.
Section 2.2.2
Connecting Low DC Power
To connect a low DC 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.
