1.9.5 Wiring the Power Inputs
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.
Figure 1-18. 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. Loosen the screws securing terminal block to the terminal block receptor.
2. Remove the terminal block from the switch.
Figure 1-19. Removing a Terminal Block
3. Insert a small flat-bladed screwdriver in the V1+/V1- wire-clamp screws, and loosen
the screws.
4. Insert the negative/positive DC wires into the V+/V- terminals of PW1. If setting up
power redundancy, connect PW2 in the same manner.
