Description of Display LEDs
Display LED Description
LED is ON when display is showing RPM. This selection of display function
is based on function code 01 or operation of PRG key while drive is running
LED is ON when display is showing Frequency. This selection of display
function is based on function code 01 or operation of PRG key while drive is
running
LED is ON when display is showing drive output current. This selection of
display function is based on function code 01 or operation of PRG key while
drive is running
LED is ON when display is showing DC bus voltage of the drive. This
selection of display function is based on function code 01 or operation of
PRG key while drive is running
If user enter Programming mode by pressing PRG key, PRG LED is ON.
This is to indicate to the user that drive is in Programming mode and cannot
be starting by giving a start command. User can exit from programming
mode by pressing key. Once drive comes out of programming
mode, PRG LED is OFF.
FORWARD LED
LED starts blinking when the motor accelerates/ decelerates in Forward
direction. When motor reaches set speed, LED stops blinking and glows
continuously.
REVERSE LED
LED starts blinking when the motor accelerates/ decelerates in Reverse
direction. When motor reaches set speed, LED stops blinking and glows
continuously.
• Pressing PRG again in programming mode, user can modify the data. In this situation
Forward and reverse LEDs will be ON along with PRG LED.
• For detailed description on programming refer to “ Description of parameters and
programming”
• Forward OR Reverse direction of the motor rotation depends on phase sequence of
motor connection and on operation of FOR/REV TB inputs.

7. INSTALLATION AND COMMISSIONING
Please follow instructions mentioned below for safe and trouble free installation of Inverter modules.
1 After receipt of the drive controller, inspection of the module is necessary as per the procedure
mentioned in “Inspection of the Module” chapter.
2 Module is designed for vertical mounting inside a panel. Always fix the module with vertical
alignment.
3 Ensure that the Mounting hole dimensions on the Panel U-sheet is as per the dimensional details
given in this manual
WARNING
• Please follow the instructions in the manual before installation and
commissioning
• Ensure to disconnect all power lines to the drive before handling or
commissioning
• Input power cable must be connected tightly and the equipment must be
grounded securely using proper grounding techniques
• When the inverter is not running, the motor terminals U,V,W will have
dangerous voltages.
• UVW terminals are for motor connections. Do not connect Power supply to
these terminals.
• Operation of the module is by authorized, trained personnel experienced in
handling high voltage electrical equipments and fixtures.
CAUTION
• When handling the inverter, please lift as a whole unit. Otherwise may
cause the main unit to fall off resulting in personal injury or damage to the
unit.
• Install the inverter on a metal base.
• Air temperature around the inverter cabinet should be maintained below
50Deg C. For this purpose use fans for air circulation inside the panel.
• Refer to Technical Specifications for environment conditions in which this
product can be operated.
• Do not install the inverter in any place exposed to dust, direct sunlight,
corrosive gas, inflammable gas or oil

4 Installation of the inverter should be done with following spacing/ clearance from panel doors/walls
or other modules. This is required to maintain enough air circulation and ease of identification and
wiring.

6 Prepare control and power cables as per the recommendations and ratings mentioned in “
Recommended cable type and terminations”. Grommets are provided to prevent entry of dust into
the module inner space.
7 Before connecting input power supply or motor to the drive module, ensure that motor shaft is free
to rotate and check for motor winding short circuit or Grounding faults.
8 Use proper lugs, ensure connectivity of the cables to the input, and output terminals on the drive
module.
9 Check proper operation of the control logic by referring to description of “ Control circuit interface”.
10 Switch ON input 415V mains voltage and measure 3-Phase input supply at INPUT terminals on the
drive module Power TBs using a multimeter in AC voltage mode.
11 On start-up, drive module displays rated input voltage and module rating on LED display
indicating input rated supply voltage selection is for 3-Ph, 415V +10% -15%,50-60Hz input
Followed by module rating in kW
Example: r7.5 indicates 7.5kW Module, r22.0 indicates 22.0kW module
If input voltage is sufficiently high and if there are no faults, drive enters Ready To Run mode.
12 Refer to “Description of Parameters and programming” to configure drive for the application
requirement.
13 Close FOR/ REV TB input to start drive controller and run the motor. If start command as per Para
02 is from Display unit, press RUN/SET key to run the motor. Drive enters RUN mode and motor
starts rotating in FOR/REV direction.
14 Refer to “Maintenance and Troubleshooting” for any problem related to controller performance and
fault condition.

WARNING
• Before switching on the input power supply ensure that there is no cable
short circuit at the input/ output terminals
Shorting of cables between U, V, W terminals and OR shorting U, V, W
terminals to ground due to cable/ connection faults will result in IGBT
failure and damage to the drive controller.

• R, Y and B are input power terminals for 415V-15%, +10%, 3-Phase supply. The connection is not
phase sensitive. The connection can be done with any phase sequence.
• U, V, W are output terminals to the motor. The motor direction is dictated by the motor winding
pattern and phase sequence. To change the direction of rotation of the motor, change the
connection sequence to the motor or the direction (FOR/REV) command to the inverter. It is
recommended to use a 3 core armored cable or cable inside an earthed metallic conduit for motor
connection to reduce the electromagnetic emission and interference.
• POS, BR are connections for optional dynamic braking resistor
• If DC Reactor is not used, NEG, -VE terminals are shorted with a suitable cable rated for the
inverter rating. If DC reactor is used, disconnect this wiring and connect DC reactor here.
CAUTION
• When using the inverter for application where the direction of rotation is
critical, check the motor direction by running it with the load disconnected.
