3.1 Power connection
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.
The power inputs are standard DB9 male connectors.
