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 2.12 Terminal Receptor: Power Input Contacts

To wire the power inputs:
Make sure the power is not connected to the modbus router 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 modbus router.
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.
5. Tighten the wire-clamp screws to secure the DC wires in place.
