WARNING
Read and understand this manual before installing, operating, or servicing this VFD. All warnings, cautions,
and instructions must be followed. All activity must be performed by qualified personnel. The VFD must be
installed according to this manual and local codes.
Do not touch any circuitry components while the main AC power is on. In addition, you must wait until the red
“CHARGE” LED is out before performing any service on that unit. (As you look at the face of the circuitry, the
“CHARGE” LED is located inside the left side of the VFD.) It may take as long as ten minutes for the charge on
the main DC bus capacitors to drop to a safe level.
Do not check signals during operation.
Do not connect the main output terminals (U/T1, V/T2, W/T3) to the incoming, three-phase AC source.
Before executing Auto-Tuning, ensure that the motor is disconnected from the drive train, and the electric
brake is set (locked) closed to ensure the load does not move. If the electric brake cannot be released, you
must ensure that the brake is disengaged for the entire tuning process.
Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while
the power is on.
Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the
power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50VDC.
To prevent electric shock, wait at least ten minutes after all indicators are OFF and measure DC bus voltage
level to confirm safe level.
Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may
be damaged by high voltage.
The VFD is suitable for circuits capable of delivering not more than 30,000 RMS symmetrical Amperes,
240VAC maximum (230V Class) and 480VAC maximum (460V Class). Install adequate branch circuit short
circuit protection per applicable codes. Failure to do so may result in equipment damage and/or personal injury.
Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection
devices to the output of the VFD. These devices may generate peak currents that exceed the VFD
specifications.
