NOTE
If your switch was shipped with a metal cover plate over the redundant power input connector, remove the cover.

The redundant power input connector on the rear of the switch contains high energy and is a burn hazard. Use
care when connecting the redundant power supply cord to the rear of the switch.

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 does not have a switch for turning the unit on and off. You disconnect power to the EPS-LD by
removing the plug from the electrical outlet. Make sure that this connection is easily accessible.
To connect the EPS-LD to power:
1 Connect the AC input power cord to the AC connector on the EPS-LD.
2 Connect the other end of the AC cord to the electrical outlet.
Make sure the electrical outlet is properly grounded.
The Power LED on the front of the EPS-LD turns solid green to indicate that it is ready.
