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.
Figure 2.14 Terminal Receptor: Power Input Contacts
To wire the power inputs:
Make sure the power is not connected to the switch or the power converter before
proceeding.
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.
