Safety Precautions
Danger
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 sym-
metrical amperes, 600 volts maximum. The three-phase AC power supply to the Drive Isolation
Transformer used with this equipment must originate from a fused disconnect 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 resistance to ground
by using the shortest possible routing. See National Electrical Code Article 250-95 or the applicable
local electrical code.
Before applying power to the controller, physically check all the power resistors and other compo-
