If the product is installed in the cabinet, make sure there are good
ventilation in the cabinet. Two products can be installed vertically
or horizontally. Horizontal layout shows in Figure 3-3. Vertical
layout shows in Figure 3-4. User can adopt any of them.
Note: If the vertical layout is adopted (especial in fan air cooling mode),
clapboard should be installed between them to avoid the upper
starter is affected by heat generated by the lower starter.

4 Operating Principle
4 Operating Principle
There are three pairs of anti-parallel thyristors connected to the stator of
motor. Using the electric switch feature of the thyristors, the voltage of the
motor can be controlled by changing the triggering angel of the thyristors.
The triggering angel of the thyristors is controlled by microprocessor. So
the motor can be started softer and smooth. After the equipment is up to
full voltage, it outputs a bypass signal. User can use this signal to control
the bypass contactor to supply the motor. See figure4-1.
