Alarm Installation Instruction
Ice Qube offers an optional alarm output that is provided through an alarm relay. This option is a dry contact (no
voltage.) The alarm will be configured both normally open and normally closed. (X03) When the alarm output is
supplied, a 120”(3048mm) cable with 3 flying leads, Common (Black), Normally Open (White), and Normally
Closed (Red) will be installed. (See Figure 6: Alarm Output)
Pre-Installation Checks
1. Ensure that the power connected to the alarm wires is in an NEC approved Class 2 circuit.
2. Check that alarm wire routing from the unit will not interfere with or become damaged by other
components.
Alarm Installation
1. Check that both the air conditioner designated power supply and the alarm power supply is de-energized
and locked out.
2. Route alarm wire cable to the desired location. The alarm wires are 18AWG stranded copper conductors.
