Wiring the Power Inputs

Caution! 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.The temperature rating of the Input Connection
Cable must be higher than 90
Warning! 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.

Figure 2.15 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.
