S3 terminal has DC 24 V against S2 terminal. However between S3 and S1, these terminals are not electrically insulated by the transformer or other device.

Notes: 1. Wiring size must comply with the applicable local and national code.

2. Power supply cables and interface unit/outdoor unit connecting cables shall not be lighter than polychloro-

prene sheathed

fl

exible cable. (Design 60245 IEC 57)

3. Install an earth longer than other cables.
