4.2.6 Door Switch Wiring
The RMU5 may be used to monitor the state of an installer-provided door switch contact. The contacts are debounced
for a programmable period. Any mechanical contact switch may be used. The door switch is wired as shown in Figure
17. Ensure that the wire jumper from the 12V terminal to the D-IN A terminal is not omitted.

The digital input may also be used to monitor other types of contacts and for other purposes. The digital input may be
used to sense breaker trips for breakers that provide isolated trip detection contacts.
For active digital sensors, such as hall effect sensors, a 3 to 32VDC source attached between D-INA and D-INB will
result in an active input for sensing an enabled voltage source. If a voltage source is used, the 12V source from the
RMU5 is not connected to D-INA.
