Electrical Installation Instruction - iceqube EX series Operation And Installation Manual

Please read the entire section before beginning the electrical installation of the Ice Qube TMS. Ice Qube air
conditioners have been designed for easy electrical power connection at one specific location on the
enclosure side of the Ice Qube TMS. Each Ice Qube TMS has been designed to operate at a range of
voltages and frequencies. See unit label(s) for correct voltage and frequency for your model(s).
***WARNING: ELECTRICAL SHOCK AND EXPLOSION HAZARD***
Electrical connections should only be completed by a qualified technician. Compliance with
all safety and electrical codes are required. Contact local authority having jurisdiction as
required. Do not connect while the circuit is energized. Turn off circuit breaker and install
lock out. The area is to be free of ignitable concentration of gases.
Pre-Installation Checks
1. Check the air conditioner model label or specification for power requirements.
2. Check the designated air conditioner power supply for adequate and proper electrical power
requirements.
3. Check that wire routing to the terminal box will not interfere with or become damaged by other
components.
Electrical Installation
1. Check that the air conditioner designated power supply is de-energized and locked out.
2. Locate customer interface electrical junction box on enclosure side of air conditioner.
Customer Interface pg:9).
Remove the (4) terminal box cover screws and remove the cover.
3.
The terminal block will be used for power.
4. Loosen bottom nut of gland on the right side of the junction box to allow for cable entry. Power
cable must be selected to meet power requirements of installed model and provide seal in the
20mm cable gland. Recommended conductor size is 14AWG. Cable type should be a flexible
conduit that is effectively clamped to prevent twisting and pulling.
5. Remove outer jacket from cable to allow sufficient length of the three conductor wire for
attachment to terminal blocks inside the junction box.
6. Strip inner jacket of the wires a length of 10mm. Remove any clear plastic coating.
7. Insert wires into the terminal blocks as shown, Line1, Line 2, and Ground. After inserting wire,
tighten terminal block screws. Check that wires are secure in terminal block and are connected to
the correct terminals
8. Position power cable so that the cable outer jacket will form a seal in the cable gland.
9. Tighten bottom nut of gland until resistance is felt on the power cable.
10. Carefully position wires inside the junction box so they will not interfere with cover replacement.
11. Reinstall the junction box with the 4 screws using a crossing pattern.
12. The system is now ready for operation.
