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 drive. All
warnings, cautions, and instructions must be followed. All activity must be performed by qualified
personnel. The drive 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 digital operator 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 drive 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 drive. These devices may generate peak currents that
exceed drive specifications.
