Connecting Low DC Power

To connect a power source to the low DC power supply, 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 to
avoid damage to transient suppression circuitry during testing.

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.
Connect the ground terminal on the power source to the chassis ground
terminal on the device.
NOTICE
Secure a European-style terminal block (or Euroblock) to one of the available
terminals.
Connect the positive wire from the power source to the positive terminal on the
terminal block.
