1 All wiring, components and materials to be procured on the site must comply with the applicable local and national codes2 Use copper conducters only.
3 As for details, see wiring diagram.4 Install circuit breaker for safety.5 All field wiring and components must be provided by licensed electrician.
6 Unit shall be grounded in compliance with the applicable local and national codes7 Wiring shown are general points-of-connection guides only and are not intended for or to include all details for a specific installation.8 Be sure to install the switch and the fuse to the power line of each equipment.
9 Install the main switch that can interrupt all the power sources in an integrated manner because this system consists of the equipment utilizing the multiple power sources.10 If there exists the possibility of reversed phase, lose phase, momentary blackout or the power goes on and off while the product is operating, attach a reversed phase protection circuit locally.
Running the product in reversed phase may break the compressor and other parts.
