*1 A breaker with at least 3.0mm contact separation in each poles shall be provided. Use earth leakage breaker (NV).
*2 Max. 80m
*3 The figures are NOT always against the ground.
S3 terminal has DC 24V against S2 terminal.
Notes
1. Wiring size must comply with the applicable local and national codes.
2. Power supply cables and the cables between Interface unit/Flow Temperature Controller and outdoor unit
shall not be lighter than polychloroprene sheathed flexible cables (Design 60245 IEC 57)
3. Be sure to connect the cables between Interface unit/Flow Temperature Controller and outdoor unit
directly to the units (no intermediate connections are allowed). Intermediate connections may result in
communication errors. If water enters at the intermediate connection point, it may cause insufficient
insulation to ground or a poor electrical contact. (If an intermediate connection is necessary, be sure to
take measures to prevent water from entering the cables.)
4. Install an earth longer than other cables.
WARNING:
In case of A-control wiring, there is high voltage potential on the S3 terminal caused by electrical circuit design
that has no electrical insulation between power line and communication signal line. Therefore, please turn on the
main power when servicing.
