Control Wiring; Emergency Shut Down - LG LK-0580CC Instrucciones De Instalación Y Mantenimiento

9. Control Wiring

Remote controller conductors are standard thermostat wire 22 to 14 ga.
Recommended wire sizes and lengths for installing the remote controller are provided in the
table on page 12. Resistance of 2 1/2 ohms per conductor can cause deviation in the
accuracy of the control.
Field Installed DC Control Wiring
Before installing the connecting wiring between the components utilizing a DC analog
output/input signal and the unit, refer to the following table for conductor sizing guidelines and;
1) Use standard copper conductor thermostat wire unless otherwise specified.
2) Ensure that the wiring between the controls and the unit's termination point does not
exceed two and a half (2 1/2) ohms/conductor for the length of the run.
3) Refer to Figure 5 for the electrical access locations provided on the unit.
4) Do not run the electrical wires transporting Sensor DC signals in or around AC wires.
Note: Resistance in excess of 2.5 ohms per conductor can cause deviations in the
accuracy of the controls
DC Conductors
Mark connections as shown in the following wiring diagram for the applicable remote
controller.

Emergency Shut Down

For Emergency Shut Down, remove the jumper between 1 and 2 and install normally closed
contacts (Open at Fault Condition). Immediate shut down will occur and the MAIN
CONTROLLER will be disabled.
Remove this conductor when connecting emergency stop device.
Filler Terminal 1
Note: To stop unit operation in case of fire, remove the jumper between terminals
1 and 2. Refer to the unit wiring diagram.
Important: After completion of wiring, check all electrical connections, including factory
wiring within the unit, and ensure all connections are tight. Replace and
secure all electrical box covers and access doors before leaving unit or
connecting power to circuit supplying unit.
