Remove the rubber bushing from the unit for the conduit tubing installation.
2. When installing the communication cables, run them through the rubber grommet attached to the unit.
3. Maintain at least 5 inch (127mm) between the power supply wiring and communication cables.
4. Prevent cables from touching or rubbing up against refrigerant piping, plate edges, and electrical
components inside the unit.
5. Completely seal the end of conduit tube with sealing materials to prevent the rain from entering the
conduit tube. (In case of wiring from bottom base)
6. Create a drainage hole at the lowest part of the conduit tube. (In case of wiring from bottom base)
2.15.3 Electrical Wiring Connections of Indoor Unit, and Outdoor Unit
(1) Connect a power supply wiring to each outdoor unit. Connect a Ground Fault Circuit Interrupter (GFCI),
fuse, and main switch (S) to each outdoor unit.
(2) Connect a power supply wiring to each indoor unit group connected to the same outdoor unit. (Total
operating current be less than 12A.)
Connect a Ground Fault Circuit Interrupter (GFCI), fuse, and main switch (S) to each indoor unit group.
(3) Connect the communication cable between indoor units, and outdoor units, as shown in Figure 2.3.
(4) Connect the communication cables in the same refrigerant system unit. (If the refrigerant piping of
indoor unit is connected to the outdoor unit, also connect the communication cables to the same indoor
unit.) Connecting the refrigerant piping and communication cables to the different refrigerant systems
may lead to malfunction.
(5) Use communication cabling that is a minimum of AWG18 (0.82mm
2
), 2-Conductor, Stranded Copper.
Shielded cable must be considered for applications and routing in areas of high EMI and other sources
of potentially excessive electrical noise to reduce the potential for communication errors. When
shielded cabling is applied, proper bonding and termination of the cable shield is required as per
Johnson Controls guidelines. Plenum and riser ratings for communication cables must be considered
per application and local code requirements. (Do not use Tri-Core or anything beyond.)
