CHAPTER 3 - INSTALLATION AND CONNECTION

Table 3.11
- Wiring separation distances
If the crossing of these cables is unavoidable, install them perpendicu-
lar, maintaining a minimum separation distance of 5cm (2 in) at the
crossing point.
Connect the shield as shown below:
6)
For wiring distances longer than 50m (150ft), it is necessary to use
galvanic isolators for the X1B:3...17signals.
7)
Relays, contactors, solenoids or electromagnetic braking coils
installed near Soft-Starters can generate interference in the control
circuit. In order to eliminate this interference, connect RC suppressors
in parallel with the coils of AC relays. Connect a free - wheeling diode
in case of DC relays/coils.
8)
When an external keypad (HMI) is used (Refer to Chapter 8),
separate the cable that connects the keypad to the Soft-Starter
SSW-06 from other cables, maintaining a minimum distance of 4 in
(10 cm) between them.

NOTE!
1)
The auxiliary electronic power supply of the SSW-06 Soft-Starter of
+24Vdc shall only be used for the supply of the digital inputs.
2)
The SSW-06 Soft-Starter factory default is with the pins 8 and 10 of
the X1B connector switched on (wire bridge).
3)
Cable cross section (0,5 to 1,5) mm
2;
4)
Maximum torque: 0.50 N.m (4.50 ibf.in).
5)
X1B wiring must be connected with shielded cables and installed
separately from other wiring (power, control at 110V/220V, etc.),
according to Table 3.11.
