3.4 Wire the Power Connectors for the Boards (DRM, DIO, or DSI)
CAUTION:
UNPLUG CONTROLLER FROM POWER OUTLET. Do not attempt to wire connectors while the
power supply is “hot”. Wiring a connector while it is “hot”
can cause electrical shock, serious injury,
death, damage to equipment, or system failure.
OBSERVE POLARITY! Failure to obey polarity can cause electrical shock, injury, death, equipment damage.
You should wire the power connectors for daughter boards while you have room to work (before you
install the boards).
Installing the boards is the following step.
1.
Remove the 2-pin (or 3-pin) Power Connectors from board packaging
(DPI, DIO, DSI).
2.
Connect the Black (GND) wire
from the Controller Power Harness to pin-2 of the power connector.
3.
Connect the RED (+12 VDC) wire
from the Controller Power Harness to pin-1 of the power connector. .
See

Pin-3 Reserved - DRM/DSI:
DRM Pin-3 is reserved for Lock Power Relay ~ requires a separate power supply (only
used for “Wet Lock Relay” operation). DSI Pin-3 is reserved for a se24 VDC Auxiliary Power Supply.
Never wire the controller’s power supply to Pin-3 on either board.
