OPERATING PRECAUTIONS
(1) Handling and installation
- The SG-series drive can be heavy. Lift according to the weight of the product. Use a hoist or a crane to
move and install the SG-series drive if necessary. Failure to do so may result in personal injury or damage
to the drive.
- Do not place heavy items on the drive. Do not stack the drive boxes higher than the number
recommended.
- Install the drive according to instructions specified in this manual.
- Check that the drive mounting orientation is correct.
- Do not drop the drive or subject it to hard impacts.
- Verify that the ground impedance is 100 ohms or less for 230 V Class drives and 10 ohms or less for 460V
class drives.
- Take protective measures against ESD (Electrostatic Discharge) before touching the PC boards during
inspection, installation, or repair.

(2) Wiring
- Do not connect power factor correction capacitors, surge suppressors, or a RFI filter to the output of the
drive.
- The connection orientation of the motor output cables U, V, W will affect the direction of rotation of the
motor. Verify correct wiring before starting drive.
- Incorrect terminal wiring could result in drive and/or equipment damage.
- Reversing the polarity (+/-) of the Px and N terminals could damage the drive.
- Only authorized personnel familiar with Benshaw drives should perform wiring and inspections.
(3) Trial run
- Check all parameters during operation. Parameter values might require adjustment depending on the
application.
- Always apply voltage within the permissible range of each terminal as indicated in this manual. Otherwise,
drive damage may result.
