»
Do not disconnect modules or cabling unless the power is first switched off. The device only
supports the voltage outlined in the type plate. Do not use any other power components
except those specifically designated for the switch device.
Power down and disconnect the power cord before servicing or wiring the switch.
There are two power inputs for normal and redundant power configurations. The power input 2 is
used for wiring a redundant power configuration. See the following for terminal block connector
views.

To wire the power inputs:
Make sure the power is not connected to the switch or the power converter before proceed ing.
1. Insert a small flat-bladed screwdriver in the V1+/V1- wire-clamp screws, and loosen the screws.
2. Insert the negative/positive DC wires into the V+/V- terminals of PW1. If setting up power
redundancy, connect PW2 in the same manner.
3. Tighten the wire-clamp screws to secure the DC wires in place.
