Installing the Device
2.6.1 Connecting AC or DC Power
WARNING
Electrocution hazard – risk of personal injury
When only one AC power source is connected to the device, the redundant power
terminals (between the positive/live and chassis/ground terminals, and between the
neutral and chassis/ground terminals) are energized. To prevent contact with the
terminals and avoid an electrical shock, do the following when one AC power source
is connected to the device:
• Make sure a terminal block is installed in the unused port and that any wires
from the secondary terminal block are properly terminated
• Make sure the first power source is off before connecting (or disconnecting) a
second power source
1. If connecting a secondary power source, make sure the power source currently
connected to the device is disabled (e.g. power cable is unplugged from the wall
receptacle).
2. Insert the appropriate terminal block(s) into the device and tighten both screws.
