INSTALLATION<br />

The line voltage must be compatible with the rated voltage<br />

of the Soft-Starter.<br />

For installation use the cable cross sections and the fuses<br />

recommended in Table 3.1, 3.2, 3.3, 3.4. Maximum torque as<br />

indicated in table 3.5.<br />

Power factor correction capacitors must never be installed<br />

on the Soft-Starter output.<br />

The Soft-Starters must be grounded. For this purpose use a<br />

cable with a cross section as indicated in Tables 3.2, 3.3, 3.4.<br />

Connect it to a specific grounding bar or to the general<br />

grounding point (resistance 10 ohms).<br />

Do not share the grounding wiring with other equipment<br />

which operate at high currents (for instance, high voltage<br />

motors, welding machines, etc.).<br />

If several Soft-Starters are used together, see Figure 3.6.<br />

Soft-Starter<br />

Do not use the neutral conductor for grounding purpose.<br />

The Soft-Starter is fitted with electronic protection against<br />

motor overloads. This protection must be set according to the<br />

specific motor.<br />

When several motors are connected to the same Soft-Starter,<br />

use individual overload relays for each motor.<br />

If a isolating switch or a contactor is inserted in the motor<br />

supply, do not operate them with running motor or when the<br />

Soft-Starter is enabled.<br />
