CAUTION: The OPL BASIC has high voltage connected to the transformer. Always disconnect power
when servicing the unit.

All electrical connections to the
OPL BASIC
system should first be verified with a meter. Application of
incorrect voltage will
permanently damage the unit and is not covered under warranty. Avoid wiring to
any power source that has large fluctuations in voltage and/or is prone to surges. Refer to the wiring
diagram in this manual for all power and signal connections. All wiring mu
st conform to local electrical
codes.
2.3.1
Main Power Connection
(Picture 2)
To wire main power connection:


Check the voltage of the main power source and make sure that it matches one of the three available input
voltages (115/208/230 VAC) of the tran
sformer;


Move the jumper to the proper terminals to set the input voltage (Picture 2) before connecting the power supply:


Disconnect all power from the laundry machine


Connect leads from the main power source to the Power terminals on the circuit board (
