Description

5+5 V (PDU use only)

6N/A

The LM10 base unit and PDU are designed to use a maximum 36-inch cable when the PDU is mounted door-mounted alone. A shorter cable can be used when the two units are door- mounted together.

The connection for the RS232 serial communications port is shown in the following figure. The EnerVista LM10 software can be used to configure and monitor the status of the LM10 through the RS232 port.
