With the power supply off or unplugged, connect it to the controller.
The SNAP-LCM4 controller requires only 5 VDC power, which can be supplied by the Opto 22 SNAP-PS5
or any 5 V power supply meeting SNAP-LCM4 power requirements.
The controller does not have a power switch; to turn it off, switch off the power supply.

Reversing wire polarity may cause damage to your controller. This damage is not covered by Opto 22’s
warranty. If in doubt about which wire is which on your power supply, check with a meter.

With the power supply off or unplugged, connect the +5 V lead from the power supply (normally
red) to the +5V terminal on the SNAP-LCM4 backplane.

Connect the COM wire from the power supply (normally black) to the GND terminal on the
SNAP-LCM4 backplane. Optionally, you can connect the earth ground terminal to panel ground.
