5. Install the supplied metal jumper between terminals 2, 4 and 6 to connect the surge ground terminals to the
chassis ground terminal. The surge ground terminals are used as the ground conductor for all surge and
transient suppression circuitry internal to the unit.
6. Connect the ground terminal on the power source to the chassis ground terminal on the device. For more

Section 2.2.2

Connecting DC Power

To connect a 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 terminal block is divided into separate terminals for each internal power supply. Make sure to
connect the external power supply to the appropriate terminals.
