Caution
This product is intended for professional use. Be sure to use a dedicated power circuit. Never use
a power supply shared by another appliance.
Above "Wire size" and "Breaker" are examples.
Regulation of wire and circuit breaker differs from each locality, refer to and be in accordance with
local rules.
To prevent electrical noise malufunction and hazards from insulation failure, the unit should be
connected to ground.
All field wiring and components must be provided by a licensed electrician.
Use copper conductors only.
Use crimp-type terminals and tighten the terminal screws to the specified torques, otherwise,
abnormal overheating may be produced and possibly cause serious damage inside the unit.
Prepare the one that the load current can be thrown enough in the capacity of the power supply.
