Safety Precautions
This equipment is designed to comply with ASME A17.1, National Electrical Code, CE, and
CAN/CSA-B44.1/ASME-A17.5 and must be installed by a qualified contractor. It is the
responsibility of the contractor to make sure that the final installation complies with all
local codes and is installed in a safe manner.
This equipment is suitable for use on a circuit capable of delivering not more than 10,000
rms symmetrical amperes, 600 volts maximum. The three-phase AC power supply to the
Drive Isolation Transformer used with this equipment must originate from a fused discon-
nect switch or circuit breaker sized in conformance to all applicable national, state, and local
electrical codes in order to provide the necessary motor branch circuit protection for the
Drive Unit and motor. Incorrect motor branch circuit protection will void the warranty and
may create a hazardous condition.
Proper grounding is vitally important to safe and successful operation. Bring your ground
wire to the system subplate. You must choose the proper conductor size and minimize the
