GS4 AC Drives Installation Instructions
Sensorless Vector Control Variable Frequency Drive
• Please read this instruction sheet thoroughly before installation and keep this instruction sheet.
• To ensure the safety of operators and equipment, only qualified personnel familiar with AC drives should
install, wire, program, and operate the GS4 drive. Always read this instruction sheet thoroughly before using
the GS4 drive, especially the WARNING, DANGER and CAUTION notes. If you have any questions, please contact
AutomationDirect.
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY
DANGER
• The ground terminal of the GS4 drive must be grounded correctly. The grounding method
must comply with the laws of the country where the GS4 drive is to be installed.
• After power has been turned off, the capacitors in the GS4 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. (Will take at least 5 minutes for
most GS4 models; 10 minutes for GS4 models ≥40hp.)
• The CMOS ICs on the internal circuit boards of the GS4 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.
• If wiring changes must be made, turn off power to the GS4 drive before making those
changes. Allow the internal DC bus capacitors in the GS4 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 GS4 drive.
• DO NOT install the GS4 drive in locations subject to high temperature, direct sunlight, or
flammable materials.
WARNING
• Never apply power to the output terminals U/T1, V/T2, W/T3 of the GS4 drive. If a fault
occurs during operation of the GS4 drive, refer to the fault code descriptions and corrective
actions to reset the fault before attempting to operate the GS4 drive.
• DO NOT use Hi-pot test for internal components. The semi-conductors in the GS4 drive are
easily damaged by high voltage.
CAUTION
• 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 GS4 drive and motor
will help to mitigate reflective wave.
• Nominal supply voltage to the GS4 drive should be less than or equal to 240 volts AC for
GS4-2xxx models, and less than or equal to 480 volts AC for GS4-4 models.
• Nominal supply current capacity should be less than or equal to 5kA RMS for GS4 models of
40hp or less, and less than or equal to 10kA RMS for GS4 models of 40hp and larger.
• The GS4 drive must be installed in a clean, well-ventilated and dry location, free from
corrosive gases or liquids.
• The GS4 drive must be stored within an ambient temperature range from –25°C to +75°C,
and relative humidity range of 0% to 90% without condensation.
• Do not apply AC power to the GS4 drive with the front cover removed. Following a fault of
the GS4 drive, wait 5 seconds before pressing the RESET key.
• To improve power factor, install a line reactor ahead of the GS4 drive. Do not install power
correction capacitors in the main AC supply circuit to the GS4 drive to prevent drive faults
due to over-current.
Minimum Wiring
• AC input power to L1, L2, 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 GS4 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 SCM1 and SCM2)
With this minimal wiring, the drive can be operated via the keypad to test the motor and drive installation.
See the “Parameter Quick-Start Set Up” (page 3) 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, safety PLC,
or E-Stop pushbutton as shown. See “GS4 with Sinking Digital Inputs” (page 1) for wiring using the GS4
internal power supply, or Appendix E of the GS4 user manual for wiring using an external power supply.
Wiring Diagrams
RFI Jumper Removal
If the power distribution system supplying the GS4 AC drive is a floating (IT) or an asymmetric
ground system, the RFI jumper must be removed.
Removing the RFI jumper uncouples the internal RFI capacitor (filter capacitor) between the GS4
drive frame and circuitry to avoid damaging those circuits and (according to IEC 61800-3) to reduce
ground leakage current.

DURApulse GS4 AC Drive Quick-Start Guide – 1st Ed, Rev.C 07/02/2021
DURApulse GS4 AC Drive Quick-Start Guide
GS4_QSP_1edRevC 07/02/2021
Quick-Start Introduction – How To Get Started
Automationdirect.com would like to thank you for your purchase of the Durapulse GS4 AC drive. The GS4 drive
is a state-of-the-art, full-featured AC drive. The Quick-Start Guide below will introduce you to many of the GS4
drive features and help you configure the GS4 drive in a minimum amount of time.
STO (Safe Torque Off) / Emergency Stop
The GS4 drive offers Safe Torque Off (STO) functionality, instead of a standard Emergency Stop circuit. STO
provides the ability to immediately turn off the output of the GS4 drive in the event of an emergency, without
the need for an emergency stop contactor between the drive and motor.
Please see P6.71 (STO Alarm Latch) in Quick-Start “Protection” Menu #4 (page 4).
Please see the Control-Circuit Wiring diagrams (page 1) for how to wire the STO circuit. From the factory,
the GS4 STO terminals are jumpered and the STO circuitry of the drive is bypassed. STO is recommended for
personnel safety.
After wiring the drive (but before applying power), the first thing you should do is press the E-stop button (or
otherwise break the safety circuit) and verify that the circuit between the STO1/STO2 terminals and the STO
+24V terminal is not connected. If these circuits are open, the STO feature will stop all power from going to the
motor and there will be no danger of unexpected movement when you power up the drive.
Powering Up the GS4 Drive
Apply AC line power to the GS4 drive, but don’t engage the safety circuit yet (keep the E-stop PB pushed in).
Starting, Stopping, and Controlling the Speed of the GS4 Drive
The GS4 drive keypad includes both LOCAL and REMOTE control modes. Out of the box, both LOCAL and
REMOTE modes of operation (selected by the buttons on the keypad) are set to use the keypad buttons to RUN
and STOP the drive and vary the drive speed. The drive can also be configured to run from potentiometers,
external pushbuttons, Ethernet communication, etc.
Do not attempt to run the motor yet. Certain parameters (especially the motor protection parameters) must
be set first.
Configure the Drive / Quick-Start Menus
The Quick-Start Menus below (press MENU on the keypad, then scroll to “Quick Start”) will guide you through
those parameters typically used in most applications. You can also navigate to any of these parameters
through the “Param Setup” menu. (Refer to page 2for information and instructions for using the Digital
Keypad.)
All applications need to configure the parameters in the “Basic Configuration” quick start menu. At minimum,
you MUST configure these motor parameters in the “Basic Configuration” menu before operating the drive:
• P0.00 Motor1 Max Output Voltage (this will typically be either 230V or 460V)
• P0.01 Motor1 Rated Amps (depends on the motor)
• P0.04 Motor1 Max Output Frequency (this will typically be 50Hz or 60Hz)
Your application will dictate which parameters need to be configured. It is NOT necessary to configure every
parameter in a Quick-Start Menu or go through each Quick-Start Menu. Use only those you need.
Menu Descriptions:
12) Basic Configuration (page 3)
Parameters in this menu are necessary to configure and protect the motor, and to define the basic control
modes of the GS4 drive. All applications should set these parameters.
13) Control I/O (page 3)
Parameters in this menu define which analog inputs and multi-speed digital inputs will control the GS4 drive.
These parameters work in conjunction with P3.00, P3.01, P4.00, P4.01 from Menu #1.
14) Enhancements (page 4)
Parameters in this menu include those parameters used to enhance or refine the operation of the GS4 drive
with features such as S-Curve, Jog Speed, Skip Frequencies, DC Injection, etc.
15) Protection (page 4)
Parameters in this menu include advanced GS4 drive protection parameters. These parameters define how
the GS4 drive will respond to certain fault conditions and whether the GS4 drive will attempt to automatically
recover.
16) PID (page 4)
Parameters in this menu are for PID control and configuration of the GS4 keypad in engineering units. More
detailed information can be found in Parameter Groups 7 and 8.
After configuring the minimum settings, you can now engage the safety circuit. The RUN and STOP buttons
should Start and Stop the drive. To adjust the output frequency, use the arrows keys to cursor to the “F”
(Frequency) setting. Press ENTER to adjust the drive’s Frequency setpoint (Up/Down arrows increase/
decrease; Left/Right arrows change the cursor position).
Parameter Quick-Start Set Up
DURApulse GS4 AC Drives offer a “Quick-Start” parameter setup from the keypad for some of the most
common drives applications. Choose “Quick-Start” from the menu, and then select one of the five menus
described in the following table. Then set the applicable parameters for that application as shown.
Please refer to the user manual if you need more detailed information about the parameters.

• External Flow Rate is across the heat sink.
• Internal Flow Rate is through the chassis.
• Published flow rates are the result of active cooling using fans, factory
installed in the drive.
• Unpublished flow rates ( - ) are the result of passive cooling in drives
without factory installed fans.
• The required airflow shown in the chart is for installing a single GS4 drive
in a confined space.
• When installing multiple GS4 drives, the required air volume would be
the required air volume for a single GS4 drive multiplied by the number
of GS4 drives.
• When calculating power
dissipation (Watt Loss), use the
Total value if the drive is foot
mounted, or the Internal value
if the drive is flange mounted.
Where only a total value is
published, these models cannot be
flange mounted. Heat dissipation
shown in the chart is for installing
a single GS4 drive in a confined
space.
• When installing multiple drives,
the volume of heat/power
dissipation should be the heat/
power dissipated by a single GS4
drive multiplied by the number of
GS4 drives.
• Heat dissipation for each model
is calculated by rated voltage,
current and default carrier
frequency.
Environment for Operation, Storage, and Transportation
DO NOT expose the GS4 drive to environments that contain dust, direct sunlight, corrosive/inflammable gases,
high humidity, liquids, or high vibration. The salt in the air must be less than 0.01 mg/cm2throughout the
year.

(inflow air temperature)
It is suggested to install a barrier
between the drives. Adjust
the size of the barrier until the
temperature of the fan on the
inflow side is lower than the
operation temperature. This barrier
is to prevent the lower drives’ hot
exhaust from going straight into
the upper drives’ intake.
(Refer to the right figure)
Operation temperature is the
temperature measured 50mm away
from the inflow side of the fan.

Note:
• The mounting clearances shown in figure to the left are NOT for installing the
GS4 drive in a confined space (such as cabinet or electric box). When installed in
a confined space, in addition to the minimum mounting clearances, ventilation
equipment or air conditioning should be installed to keep the surrounding
temperature lower than the operation temperature.
• The following table shows heat dissipation and required air volume when installing
a single GS4 drive in a confined space. When installing multiple drives, the required
air volume shall be multiplied by the number of GS4 drives.
• Refer to the chart (Air flow rate for cooling) for ventilation equipment design and
selection.
• Refer to the chart (Power Dissipation) for air conditioner design and selection.
• If GS4 drives in frames sizes A thru D are installed with clearance dimensions less
than specified, the cooling fans in these models may not adequately cool the drive.
