GS20 AC Drives Installation Instructions

Sensorless Vector Control Variable Frequency Micro-drive

• Please read this instruction sheet thoroughly before installation and retain for later

reference.

• To ensure the safety of operators and equipment, only qualified personnel familiar

with AC drives should install, wire, program, and operate the GS20 drive. Always read this instruction sheet

thoroughly before using the GS20 drive, especially the WARNING, DANGER and CAUTION notes. If you have any

questions, please contact AutomationDirect.

PLEASE READ PRIOR TO INSTALLATION FOR SAFETY

• The ground terminal of the GS20 drive must be grounded correctly. The grounding method

must comply with the laws of the country where the GS20 drive is to be installed.

• After power has been turned off, the capacitors in the GS20 drive may retain a charge for

several minutes. To prevent personal injury, visually verify that the "CHARGE" LED has

turned off. Then measure to confirm that the DC bus voltage level between terminals (+1)

and (-) is less than 25VDC before touching any terminals. (Capacitor discharge will take at

least 5 minutes for most GS20 models)

• The CMOS ICs on the internal circuit boards of the GS20 drive are sensitive to static

electricity. Please DO NOT touch the circuit boards with your bare hands before taking

anti-static measures. Never disassemble the internal components or circuits.

DANGER

• If wiring changes must be made, turn off power to the GS20 drive before making those

changes. Allow the internal DC bus capacitors in the GS20 drive sufficient time to discharge

prior to making changes in power or control wiring. Failure to do so may result in short

circuit and fire. To ensure personal safety, allow DC bus voltage to discharge to a safe level

before making wiring changes to the GS20 drive.

• DO NOT install the GS20 drive in locations subject to high temperature, direct sunlight, or

flammable materials.

• Never apply power to the output terminals U/T1, V/T2, W/T3 of the GS20 drive. If a fault

occurs during operation of the GS20 drive, refer to the fault code descriptions and corrective

actions to reset the fault before attempting to operate the GS20 drive.

• DO NOT use Hi-pot test for internal components. The semi-conductors in the GS20 drive are

WARNING

easily damaged by high voltage.

• Long motor lead lengths may result in reflective wave due to impedance mismatch between

the motor cable and the motor. Reflective wave may damage the insulation of the motor.

To avoid the possibility of reflective wave damage, use an inverter-rated motor with an

insulation rating of 1600 volts. A load reactor installed between the GS20 drive and motor

will help to mitigate reflective wave.

• Nominal supply voltage to the GS20 drive should be less than or equal to 120/240/480 volts

AC depending on GS20 model.

• Nominal supply current capacity should be less than or equal to 100kA for all GS20 models.

• The GS20 drive must be installed in a clean, well-ventilated and dry location, free from

corrosive gases or liquids.

CAUTION

• The GS20 drive must be stored within an ambient temperature range from –40°C to +85°C,

and relative humidity range of 0% to 90% without condensation.

• Do not apply AC power to the GS20 drive with the front cover removed. Following a fault of

the GS20 drive, wait 5 seconds before pressing the RESET key.

• To improve power factor, install a line reactor ahead of the GS20 drive. Do not install power

correction capacitors in the main AC supply circuit to the GS20 drive to prevent drive faults

due to over-current.

Minimum Wiring

• AC input power to R/L1, S/L2, T/L3 (for single-phase input, use two of the terminals) (For applicability of 1-phase

input power, please refer to Chapter 1 of the DURApulse GS20 AC Drives User Manual at AutomationDirect.com.)

• Ground from the power supply

• Drive power to the motor (U, V, W on T1, T2, T3) (For use with 3-phase motors only!)

• Ground to the motor

• STO1 and STO2 (both must be wired through appropriate N.C. safety-rated contacts to DCM or the

factory-installed jumpers must be left in place)

With this minimal wiring, the drive can be operated via the keypad to test the motor and drive installation.

See the "Parameter Set Up"

(page

4) section to configure the drive for keypad operation.

Recommended Safety Wiring

We strongly recommend that customers use the STO safety feature.

The Safe Torque Off (STO) function turns off the power supplied to the motor through the hardware, so

that the motor cannot produce torque. This method of removing power from the motor is considered an

emergency stop, also known as "coast to stop."

To use this feature, disconnect the appropriate factory-installed jumpers and wire a safety relay or safety PLC

as shown. The E-Stop pushbutton should be wired through a Safety Relay or PLC to meet Category 3 safety

requirements. See User Manual Appendix E for wiring the GS20 with STO.

Wiring Diagrams

RFI Jumper Removal

If the power distribution system supplying the GS20 AC drive is a floating (IT) or an

asymmetric ground system (including most 120V inputs), the RFI jumper must be

removed.

Removing the RFI jumper uncouples the internal RFI capacitor (filter capacitor)

between the GS20 drive frame and circuitry to avoid damaging those circuits and

(according to IEC 61800-3) to reduce ground leakage current.

When a fault occurs, the MC contactor

switches to OFF to shut off the drive input

power and protect the power system.

R1C and R1 are the relay output terminals.
