WIRING AND DIP SWITCHES
All wiring to the DPM is done via rear terminal, de-pluggable connectors. Up to five
headers accept the wired connectors on the DPM. All units have at least two head-
ers, power input and signal input. Any combination of three additional circuit boards
with headers may be installed. These option boards are relay output, RS 485 serial
communications, and analog retransmission. The option boards occupy specific
locations in the DPM and are not interchangeable. All boards are keyed to prevent
installation in the wrong location.
Disconnect all power before wiring terminals. A safety hazard exists if
this precaution is not observed. Treat all control and count inputs as haz-
ardous since they may carry line voltage.
