ELECTRICAL WIRING
Outdoor Unit Electrical Connections
Connecting Outdoor Unit Electrical Wiring
The general guidelines for connecting electrical and communication cables to the outdoor unit are the same for each of the Single Zone Wall
Mount units, however, the actual connections on the terminal block will differ. See each illustration for the Single Zone unit model that you are
installing for correct wiring of each terminal block.
•
Be sure that main power to the unit is completely off before pro-
ceeding with these steps. Follow all safety and warning information
outlined at the beginning of this manual. Failure to do so, may cause
bodily injury.
•
Be sure that a circuit breaker or some other emergency power cutoff
device is in place before any power wiring is done to the system.
Failure to do so, may cause bodily injury or death.
•
Never touch any power lines or live cables before all power is cutoff
to the system. To do so, may cause bodily injury or death.

Procedure
Refer to Figure 55 regarding how a circuit breaker should be wired
through to the Single Zone system.
•
Be sure there is no power going through the Single Zone system before
proceeding with these connections as it may result in electric shock.
•
Familiarize yourself with the location of the circuit breaker and be
sure that all power is cut to the Single Zone unit as it may result in
electric shock.
1. Using a phillips head screwdriver, remove the conduit panel cover
from the outside unit.
2. Before proceeding, inspect all wiring inside the casing to be sure
they are secure and have not come loose during transportation
and installation of the outdoor unit.
•
Loose wires can cause the wiring to burn out quickly.
•
Inspect wires for any damage or cracks (manufacturing defects).
3. Confirm that electrical power supply capacity is sufficient to run
the unit. See specifications sheets at the beginning of this instal-
lation manual for details on power.
4. Confirm that you are using the right gauge size for wiring to
proceed.
5. Using a screwdriver, connect the wires as shown in Figure 56 and
Figure 57.
•
Each wire should be securely attached to the terminal block.
•
Bundle the cabling by using a cable restrainer.
•
Pay attention to the location/connection of the green/yellow
grounding cable.
•
Maintain a minimum of .2” of wire length from terminal block to
cable bundle.
