INSTALLATION<br />
When installing the signal and control wiring, please note<br />
the following:<br />
Cable cross-section: 0.5...1.5mm 2 ;<br />
Relays, contactors, solenoid valves or breaking coils<br />
installed near to Soft-Starters can generate interferences in<br />
the control circuit. To eliminate this, you must install RC<br />
supressors connected in parallel with the coils of these device,<br />
when fed by alternate current and free wheel diodes when<br />
fed by direct current.<br />
When an extern HMI is used, the connection cable to the<br />
Soft-Starter should be passed through the slot at the bottom<br />
of the Soft-Starter.This cable must be laid separate from the<br />
other cables existing in the installation, maintaining a<br />
distance of 100mm (3.94in) each other.<br />
Max. recommended torque in the terminals X2 and X1:<br />
Maximum 0.5 Nm or 4.5lb.in.<br />
The control wiring (X2:1...9) must be laid separate from<br />
the power wiring.<br />
3.2.4 - FAN<br />
CONNECTIONS<br />
The fans connections must be done through X7:1 and X7:2<br />
connector, according to the voltage defined by the Soft-Starter<br />
code:<br />
Ex.: SSW-03. 205/220-440/<br />
- PL<br />
Electronic / fan voltage:<br />
1 = 110Vac<br />
2 = 220Vac<br />
