Wiring Power Supply
1.
Connect the "positive" cable to the "+V" terminal, and the “negative” to the "0V" terminal.
Always connect the functional earth pin to the earth ground. Use a dedicated wire for this purpose; it must
not exceed 1 meter.
Do not connect the neutral or line signal of the 110/220VAC to the device’s 0V pin.
In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the
device to a regulated power supply.
A non-isolated power supply can be used provided that a 0V signal is connected to the chassis.
Note that both the OPLC and the EX-A2X must be connected to the same power supply.
The EX-A2X and the OPLC must be turned on and off simultaneously.
