For HVDC input, connect a Saf-D-Grid DC cable to a Saf-D-Grid receptacle, otherwise:
a) Connect the ground terminal ring on the power cable to the ground terminal on the DC power source and
secure it in place with a nut tightened to the appropriate torque setting for the terminal post.
b) Connect the negative terminal ring on the power cable to the negative (-) terminal on the DC power source
and secure it in place with a nut tightened to the appropriate torque setting for the terminal post.
c) Connect the positive terminal ring on the power cable to the negative (+) terminal on the DC power source
and secure it in place with a nut tightened to the appropriate torque setting for the terminal post.
Step 4
Verify that the Saf-D-Grid plug is plugged in completely to secure the built-in retaining latch.
