Note: The solid line represents the recommended wiring diagram which carries the least wiring for
ensuring system operation. The dotted line represents the wiring diagram used when discrepancy
occurred to the configuration of integrated machine.

4.2 Recommended wiring process

The terminal layout of 15–22kW, 30kW–37kW and 45–90kW slightly differs from each other. 15–
22kW and 45–90kW are taken as examples for wall-mounting wiring.
