Figure 15. Typical Power Wiring Diagram (VRF Heat Recovery System Shown)

Indoor units and MS boxes on the same refrigeration

circuit should have a common power supply but must
have an independent disconnect switch installed adjacent
to the fan coil for servicing and maintenance purposes.

Indoor unit and MS box power supply MUST not be taken

from the outdoor unit. Always follow NEC/CEC and Local

Codes.
