), insert the
Saf-D-Grid connector on the power cable to the power receptacle on the power supply until it clicks in place.
2.
Connect the other end of the power cable to the power source.
• If connecting to an AC power source, plug the cable into the receptacle for the power source.
• If connecting to a DC power source, do the following:
1.
Verify that the power source is turned off at the circuit breaker located between the power source and
the terminals where you will connect the power cable.
2.
Connect each of the three wires in the power cable to the three terminals for the power source and
secure them with the terminal nuts. Make sure that the positive wire is attached to the positive terminal,
the negative wire is attached to the negative terminal, and the ground wire is attached to the ground
terminal.
