Limitless™ WPMM Series
5.2
Electrical Connections
WARNING
RISK OF ELECTRICAL SHOCK
* Potential shock hazard where HAZARDOUS LIVE voltages greater than 30 Vrms, 42.4 Vpeak, or 60 Vdc
may be accessible.
Failure to comply with these instructions could result in death or serious injury.
ATTENTION
Do not run the electrical wires in parallel and close proximity to the antenna or antenna cable.
Power supply connections: The WPMM has three 0.25 in quick connect terminals on the bottom of the housing. A
regulated voltage supply of 10 Vdc to 30 Vdc needs to be connected to the terminals identified with a "V+" and
"V-". See Figure 2.
NPN output connections (optional): The WPMM is supplied with a NPN normally open current sinking output.
The customer has the option of connecting their NPN current sinking-compatible circuitry to the terminals identified
with an "OUT" and "V-". See Figure 3.

Start-up or Re-start Sequence
Turn-on the power to the "V+" and "V-" terminals (after proper connection described in Section 5.2) which will initiate
a check of the LEDs and buzzer on the WPMM. If properly working, red, amber, and green LEDs illuminate along
with the buzzer sounding for approximately three seconds.
The following describes how the WPMM LEDs will indicate that the WPMM is ready for use:
Zero switches paired (per Section 5.4) to the WPMM: The green LED will illuminate indicating power is being
supplied to the WPMM and the unit is ready to use.
One or more switches paired (per Section 5.4) to the WPMM: The WPMM will enter a System Check Mode for
up to two minutes. The red, amber, and green LEDs illuminate sequentially until the system check is successfully
completed at which time the green LED will illuminate indicating power is being supplied to the WPMM and the unit
is ready to use.
ATTENTION
If there are multiple WPMMs being used in the application, apply power to previously paired WPMMs
first (if any) and then to one WPMM at a time. Allow time for each WPMM to complete its start-up
sequence before applying power to the next WPMM.
