Section 2.2.2
Connecting DC Power
To connect a single high or 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 metal jumper. This metal jumper connects transient suppression circuitry to chassis
ground and must be removed in order to avoid damage to transient suppression circuitry during testing.
NOTE
The screw-type terminal block is installed using Philips screws and compression plates, allowing either
bare wire connections or crimped terminal lugs. Use #6 size ring lugs for secure, reliable screws, which
must be removed to make connections.
