Controller
—ATTENTION —————————————
⎯⎯⎯⎯⎯⎯
Do not apply DC power to controllers served by the power
supply until all connections have been made between the
power supply and the controller(s). If po wer is applied to a
controller before all connections have been made, the
power supply may become overloaded, causing a circuit
breaker to tri p or ot her power supply damage to res ult or
possibly causing damage to products served by the power
supply.
4. Wiring from the power supply to the controller box must
be run in conduit using 14 GA (2.5mm
2
) wire for the AC
Ground, DC Common, 12V and 24V.
5. Turn the voltage adjustment on the 12 V power supply
counter clockwise. This is done to re duce power
dissipation in the enclosure.
6. Connect the AC Ground, DC Common, 12V and 24V to
