The line voltage must be compatible with the rated voltage
of the Soft-Starter.
For installation use the cable cross sections and the fuses
recommended in Table 3.1, 3.2, 3.3, 3.4. Maximum torque as
indicated in table 3.5.
Power factor correction capacitors must never be installed
on the Soft-Starter output.
The Soft-Starters must be grounded. For this purpose use a
cable with a cross section as indicated in Tables 3.2, 3.3, 3.4.
Connect it to a specific grounding bar or to the general
grounding point (resistance 10 ohms).
Do not share the grounding wiring with other equipment
which operate at high currents (for instance, high voltage
motors, welding machines, etc.).
If several Soft-Starters are used together, see Figure 3.6.

The Soft-Starter is fitted with electronic protection against
motor overloads. This protection must be set according to the
specific motor.
When several motors are connected to the same Soft-Starter,
use individual overload relays for each motor.
If a isolating switch or a contactor is inserted in the motor
supply, do not operate them with running motor or when the
Soft-Starter is enabled.
