WATT-TRONIC S3 / H3 SERIES
Thank you for purchasing this WATT-Inverter variable frequency AC motor drive. When properly
installed, operated and maintained, the S3 / H3 series will provide a lifetime of reliable operation. It is
mandatory that the person who operates, inspects, and maintains this equipment thoroughly reads and
understands this manual.
This instruction manual has been designed to serve as self-supporting guide for the proper installation.
Feel free to contact either your local supplier or WATT drive, should you need any assistance.
PLEASE READ AND UNDERSTAND THIS MANUAL BEFORE
OPERATING THE WATT-INVERTER
This will ensure safe and reliable operation of the Inverter.
PRECAUTIONS
1. Make sure input power is in accordance with WATT-tronic series.
2. AC mains power connection L1, L2 and L3 (L1 & L2 for 240 volt single phase input) Motor
connections T1, T2 and T3.
3. DO NOT touch any circuit components while AC main power is on or immediately after the
mains AC power is disconnected from the unit. You must wait until the LED on the control
board to extinguish.
4. DO NOT make any interconnection or investigation to the circuit before Inverter is disconnected
from AC power line. Failure to adhere to this warning could result in serious or lethal injury.
IT IS STRONGLY RECOMMENDED THIS MANUAL IS READ AND UNDERSTOOD TO
OBTAIN OPTIMUM OPERATION FROM YOUR WATT-tronic S3 / H3 series.

1. SELECTION INTRODUCTION
1.1 General
S3 / H3 series are high performance general purpose inverters that incorporate a high efficiency
Pulse Width Modulated (PWM) design and IGBT technology. The output closely approximates
a sinusoidal current wave form to allow variable speed control of any conventional squirrel cage induction
motor.
1.2 Receiving
This unit has been put through demanding tests at the factory prior to shipment.
Before unpacking please check the following:
1. Identify the description of the product found on the label with your
purchase order.
2. Inspect for transport damage (serious damage of carton may lead to unit damage)
Please check the followings after unpacking:
a. Check if the specifications (current & voltage) on the front cover match your
application requirement.
b. Check all the electrical connections and screws.
c. Verify there is no visible damage to any of the components.
If any part of the Inverter is damaged or lost, please notify the carrier and WATT-drive immediately.

2. SELECTION INSTALLATION
2.1 Location
Proper location of the WATT-Inverter is imperative to achieve specified performance & normal operation
lifetime. The Inverter should always be installed in areas where the following conditions exist.
* Ambient operating temperature:
Enclosed type: -10°to 40 °C (14°to 104 °F)
* IP rating : IP 20 for all models.
* Protected from rain & moisture.
* Shielded from direct sunshine.
* Free from metallic particles and corrosive gas.
* Free from excessive vibration. (below 0.5G)
2.2 Positioning
For effective ventilation and maintenance purposes, sufficient clearance (as shown in figure 2.1) around
the WATT-tronic is necessary . The Inverter must be installed with heat sink ribs oriented vertically.

2.3 Changing PC boards
1. Set Fn_95 to 1111
2. Set Fn_00 to match the specified model (Refer to Fn_00)
3. Set Fn-95 to 1111
4. Detect the P-N DC voltage and input the value into Fn_96. ( P is on TM1, N
is the test pin on main board)

SETTING RANGE:
The setting of accel. / decel. time and frequency are only 4 digits when set by keypad (for example: 3599
sec / 399.9 Hz), but 5 digits (for example: 3599.9 sec or 399.99 Hz) when controlled by programmable
controller (PLC) or computer communication mode.

Fn_01 : Acceleration time 1 = 0.1 - 3,600 sec.
Fn_02 : Deceleration time 1 = 0.1 - 3,600 sec.
Fn_49 : Acceleration time 2 = 0.1 - 3,600 sec.
Fn_50 : Deceleration time 2 = 0.1 - 3,600 sec.
Fn_80 : S curve time 1 in the period of Accel./decel. time 1 = 0 - 4 sec.
Fn_81 : S curve time 2 in the period of Accel./decel. time 1 = 0 - 4 sec.
1. Formula for calculating accel./decel. time
Preset frequency
Accel. time = Fn_01(or Fn_49) X ;
60Hz
Preset frequency
Decel. time = Fn_02 (or Fn_50) X
60Hz
2. Accel. time 1 or 2\ Decel time 1 or 2\ S curve 1 or 2 can be controlled by on/off signal of
external input terminal as long as Fn_56, Fn_57 or Fn_58 is set to 4.
3. S curve will be disabled, which means linear acceleration and deceleration, when Fn_80/
Fn_81 is set to 0.
4. Acceleration and Deceleration curve will be as indicated below if time of S curve
(Fn_80\Fn_81) is greater than 0.

FREQUENCY
5. Actual accel.\decel. time = preset accel.\decel time + S curve time if ignoring stall situation.
Fn-03 : Remote Operation Select = xx00 : FWD/STOP, REV/STOP

x0xx : REV command enable
x1xx : REV command disable
0xxx : During Fn_11=3 ( TM2 up/down control), the
setting frequency will remain at the last operation
frequency when stop.
1xxx : During Fn_11=3 ( TM2 up/down control), the
setting frequency will be back to 0 when stop
Remark 1 : Fn_03 will be enabled only when Fn_10 = 1(Remote control).
Remark 2 : “STOP” key on digital operator can be used for emergency stop ( Refer to
Fn_48), when Fn_10=1
