ELECTRICAL SYSTEM INSTALLATION
Outdoor Unit Electrical Connections
5. Unscrew the screws to the cable clamps, and then open the cable clamps. There is one cable
clamp for the power wiring to the outdoor unit, and one cable clamp for the communication /
connection (power) cable to the indoor unit.
6. Guide the outdoor unit power wiring, and communication / connection (power) cable through
the separate access holes (see image at right). If installing conduits to protect the commu-
nication / connection (power) cable, see "Using a Conduit for Indoor Unit Wiring / Cable
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 for the separate access holes. Commu-
nication problems will occur.
7. Using a JIS screwdriver, securely 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.
• Outdoor unit wire color and terminal number must match the indoor unit wire color and terminal
number.
• Pay attention to the location / connection of the ground cable.
• Maintain a minimum of 1/4 inches of wire length from terminal block to conduit / bundle.
Loose wires will cause electric shock, bodily injury and / or death.
Loose wires can cause the wiring to burn out, damaging the outdoor unit.
8. Close the cable clamps, and secure them with the screws.
Do not secure the outdoor unit power wiring and the communication / connection (power) cable to the indoor unit using the same cable clamp. Use
the two separate clamps. Communication problems will occur.
9. When finished, reattach the side panel to the outdoor unit with the four (4) screws.
Connecting the Conduit at the Outdoor Unit
HLV3 outdoor units have holes on the side to access the control panel. Insert the other end of
the conduit to the outdoor unit access hole with a grommet and washer (field-supplied with the
connector) as shown.
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 for the separate access holes. Commu-
nication problems will occur.
