iv
WARNING
Do not remove the cover while power is applied or the unit is in operation.
Do not operate the drive with the front cover removed. Electric shock can occur due to
the exposed terminals and bus bars.
Do not remove the cover except for periodic inspections or wiring, even if the input
power is not applied. The capacitor bank may remain charged for some time even when
power is not applied.
Wiring and periodic inspections should be performed at least 10 minutes after
disconnecting the input power and after checking that the DC link voltage is discharged
with a meter (below 30VDC).
CAUTION
Install the drive on a non-flammable surface. Do not place flammable materials nearby.
Disconnect the input power if the drive has been damaged. Do not apply power to a
damaged drive or to a drive with parts missing.
Do not connect a resistance directly between the DC Bus terminals (P1 (or P2)) and N.
Doing so can result in overheating and damaging the resistor.
After shutting down or disconnecting the drive, the drive may be hot to the touch.
Verify that the power-up restart feature is off during servicing to prevent any
unexpected operation.
Do not allow lint, paper, wood chips, dust, metallic chips or other foreign material into
the drive.

v
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.
- The drive is designed for use under the following environmental conditions:
Environment
Ambient temp. - 10 ~ 40 C (14F ~ 104F)
Relative
humidity 90% Relative Humidity or less (non-condensing)
Storage temp. - 20 ~ 65 C (-4F ~ 149F)
Location Protected from corrosive gas, combustible gas, oil mist or
dust. (Pollution Class 2 environment)
Altitude,
Vibration
Max. 3300 ft. (1000m) above sea level
Max. 5.9m/sec2(0.6G) or less
Atmospheric
pressure 10~15 PSI (70 ~ 106 kPa, 20.67 in Hg ~ 31.3 in Hg)
(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.

vi
(4) Operation precautions
- When the Auto restart function is selected the drive will restart after a fault has occurred.
- The Stop key on the keypad is always active regardless of drive control (start/stop) methods set in
parameters DRV-03 and DRV-91.
- If Restart after Fault Reset (AFN-21) is set to “yes”, and a fault reset is made with the run command and/or
reference signal present, a sudden start will occur. Verify correct setting of this parameter and check that
the run command and/or reference signal is turned off in advance of resetting any faults.
- Do not modify the drive.
- Depending on the motor specifications and user ETH overload settings, the motor may not be protected by
electronic thermal function of drive.
- The operation of the drive is intended to be controlled by either keypad command or control input signals.
Do not use a magnetic contactor or any other device that routinely disconnects the drive and reconnects the
drive to the input supply power for the purpose of starting and stopping the motor.
- A noise filter may be installed to reduce the effect of electromagnetic interference. Consult factory for
more information.
- In cases withinput voltage unbalances, install an AC input reactor.
- Power Factor capacitors and generators may become overheated and damaged due to harmonics created by
the drive.
- Use an inverter duty rated motor or take measures to suppress the surge voltage at the motor with a dV/dT
filter or equivalent. A surge voltage attributable to wiring constant is generated at the motor terminals and
may deteriorate mtoor insulation.
- The drive can be set to operate a motor at high-speeds. Verify the speed capability of motor and machinery
prior to operating drive.
- Holding torque is not produced when using the DC-Brake function. Install separate equipment when
holding torque is required.
(5) Fault prevention precautions
- If required, provide a safety backup such as an emergency mechanical brake to prevent any hazardous
conditions if the drive fails during operation.
(6) Maintenance, inspection and parts replacement
- Do not Meggar (hi-pot or insulation resistance) test the power or control circuits of the drive.
- Refer to Chapter 7 for periodic inspection and parts replacement details.
(7) General instructions
Many of the diagrams and drawings in this instruction manual may show the drive covers removed. Prior to
operating the unit, be sure to restore covers and circuit protection according to specifications.
