1.1 Power connection

Figure 3 shows the power connections of the unit as well as the RS-422 connections.

The Power inputs are constructed to provide redundancy when using two external power
supplies. When supplying power to one of the connectors it is not possible to source power
from the second power connector. Tighten the screws to ensure a proper contact.
