Connecting the EPS-LD to Power
Make sure the EPS-LD is connected to the switch before you connect the AC power.
CAUTION
The EPS-LD unit does not have a switch for turning the unit on and off. You disconnect power to the
EPS-LD unit by removing the plug from the electrical outlet. Ensure that this connection is easily
accessible to you.
NOTE
Consider all the equipment connected to the power supply circuit to ensure that the circuit is not
overloaded. Use proper over-current protection, such as a circuit breaker, to prevent over-current
conditions.
To connect the EPS-LD to power:
1
Connect the AC input power cable to the AC connector on the EPS-LD unit.
2 Connect the other end of the AC cable to the electrical outlet.
Make sure the electrical outlet is properly grounded.
The Power LED on the front of the EPS-LD unit turns solid green to indicate that it is ready. Table 23
shows the possible LED status for the power supply.
