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.
The control terminal block is a phoenix contact style 0.2-inch center, dual-row, 16 points
per row removable connector. The connector will be used to make all field connections
(other than communications and CT sensors) to the unit. The terminal block has the
following connections:
