SAFETY INSTRUCTIONS

To prevent injury and property damage, follow these instructions during the

installation and operation of the drive.

Incorrect operation due to ignoring these instructions may cause harm or

damage. The following symbols are used throughout the manual to highlight

important information.

DANGER

WARNING

CAUTION

This symbol indicates the possibility of

death or serious in

This symbol indicates the possibility of

damage to the drive or other components.

This symbol indicates death or serious injury

can occur if you do not follow instructions.

■The meaning of each symbol in this manual and on your equipment is as

follows.

This is the safety alert symbol.

Read and follow instructions carefully to avoid a dangerous situation.

This symbol alerts the user to the presence of “dangerous voltage” inside the

roduct that might cause bodily harm or electric shock.

■This manual should be placed in a location where it can be accessed by users.

■This manual should be given to the person who actually uses the drive and is

responsible for its maintenance.

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.

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.

(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.
