RLA: Rated Load Ampacity (A)
LRA: Locked Rotor Ampacity (A)
FLA: Full Load Ampacity (A)
NOTES:
1. Select wire size based on the value of MCA.
2. MOP is used to select the fuse, circuit breaker, or a Ground Fault Circuit Interrupter (GFCI).
3. Communication cabling shall be 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.
Install a multi-pole main switch with a space of 1/8 inch (3.5mm) or more between each phase.
NOTES:
1. When the power supply wiring is longer, select the minimum wiring size which the voltage drop is within 2%.
2. Power voltage ranges are the following.
Supply Voltage: Rated Voltage within + 10%
Starting Voltage: Rated Voltage within -15%
Operating Voltage: Rated Voltage within + 10%
3. Do not connect the ground wiring to gas piping, water piping, or a lightening conductor.
Gas Piping: An explosion and ignition may occur if there is escaping gas.
Water Piping: There is no effective electrical ground provided when hard vinyl piping is used.
Lightning Conductor: The electrical potential of the earth increases when a lightening conductor is used.
