WARNINGHazardous Voltage!Disconnect all electric power, including remote disconnectsbefore servicing. Follow proper lockout/tagout proceduresto ensure the power can not be inadvertentlyenergized. Failure to disconnect power before servicingcould result in death or serious injury.Failure to disconnect power before servicing can cause severepersonal injury or death.The transformer is located in the control panel. The circuitbreaker is located on the left side of the transformer andcan be reset by pressing in on the black reset button.Controls using 24 VACBefore installing any connecting wiring, refer to Figure 2-1for the electrical access locations provided on the unit andTable 2 for AC conductor sizing guidelines, and;a. Use copper conductors unless otherwise specified.b. Ensure that the AC control wiring between the controlsand the unit’s termination point does not exceed three (3)ohms/conductor for the length of the run.Note: Resistance in excess of 3 ohms per conductormay cause component failure due to insufficient ACvoltage supply.c. Be sure to check all loads and conductors for grounds,shorts, and mis-wiring.d. Do not run the AC low voltage wiring in the same conduitwith the high voltage power wiring.e.

Table 3 lists the conductor sizing guidelines that must befollowed when interconnecting the DC binary output devicesand the system components utilizing a DC analoginput\output signal to the unit.Note: Resistance in excess of 2.5 ohms perconductor can cause deviations in the accuracy ofthe controls.b. Ensure that the wiring between controls and the unit’s terminationpoint does not exceed two and a half (2.5)ohms/conductor for the length of the run.c. Do not run the electrical wires transporting DC signals inor around conduit housing high voltage wires.d.
