INSTALLATION
Locate the unit inside a UL Listed enclosure, such as a BASE
LVPC Power Cabinet or Econo•
Box,
close to the source pow-
er supply. Drill or punch (4) 0.187” diameter holes (3/16) to
match the (4) corner holes in the printed circuit board. Push the
nylon standoffs supplied into each hole and snap the module
into place.
POWER SUPPLY WIRING
Common Power Supply for Outputs and Disc Relay Control
Do not cut Common Power Jumpers. Connect 12 or 24VDC
power supply input leads to the
MAIN POWER
input terminals
at the lower right side of the module. See Power Input Wiring
Diagram 1.
Separate Power Supplies for Outputs and Disc Relay Control
Cut both Common Power Jumpers. Connect 12 or 24VDC Re-
lay Control power supply input leads to the
DIS RLY POWER
input terminals at the lower right side of the module.
Connect 12-24VAC/DC Door Lock power supply input leads
to the
MAIN POWER
input terminals at the lower right side of
the module. See Power Input Wiring Diagram 2.
Installation and Operations Manual
WARNING
Turn off all power feeding the module terminals before servicing or changing input/output
wiring, removing or replacing fuses, etc. Failure to observe this warning may cause electrical shock hazard or
may damage internal or external circuit components.
