1. Safety precautions 1.3. Before electric work Caution: • Be sure to install circuit breakers. If not installed, electric shock may result. • For the power lines, use standard cables of sufficient capacity. Otherwise, a short circuit, overheating, or fire may result. • When installing the power lines, do not apply tension to the cables. If the connections are loosened, the cables can snap or break and overheating or fire may result. • Be sure to ground the unit.
