ELECTRICAL SYSTEM INSTALLATION

Do not install power wiring to the outdoor unit

and the communication / connection (power) cable

to the indoor unit in the same conduit. Use separate

conduits. Communication problems will occur.

Figure 94: Example of Conduit.

Connecting Outdoor Unit Wiring, continued.

6. Using a JIS screwdriver, connect wires as shown at right. See

also indoor unit wiring diagram found on its bottom cover, and

outdoor unit wiring diagram on the inside of its chassis cover.

• Each wire must be individually and securely attached to each

terminal.

Loose, damaged, or cracked wires will cause electric shock, bodily

injury and / or death.

Loose wires can cause the wiring to burn out, damaging the outdoor

unit.

• Secure wiring / cables with cable ties.

• Pay attention to the location / connection of the ground cable.

• Maintain a minimum of 1/4 inches of wire length from terminal block

to cable bundle.

7. When finished, reattach the piping / control box cover or con-

trol box cover (depends on model) to the outdoor unit with the

screws.

Outdoor Unit Electrical Connections

LS090-120HEV2, LS090-120HFV3 and LS090-120HXV2 indoor units and outdoor units have similar frames; however,

LS090-120HEV2 and LS090-120HFV3 systems require 208-230V, 60Hz, 1ph power supply. LS090-120HXV2 systems require

115V, 60Hz, 1ph power supply. Verify which system is being installed. An incorrect power supply will result in electric shock,

re, physical injury, or death.
