1 Introduction
WARNING
Do not touch any circuitry components while the main AC power is on. In addition, wait until the red “CHARGE”
LED is out before performing any service on that unit. It may take as long as 5 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 a rotational Auto-Tuning, ensure that the motor is disconnected from the drive train and the
electric brake is released. If the electric brake cannot be released, you must ensure that the brake is
disengaged for the entire tuning process.
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 connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while
the power is on. Do not remove or insert the keypad while 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 50 VDC.
To prevent electric shock, wait at least five minutes after all indicators are OFF and measure DC bus voltage 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 100,000 RMS symmetrical Amperes. 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 VFD specifications.
