SSW7000 | 5-32
Installation and Connection
The analog inputs and outputs are programmed to operate in the 0 to 10 V range as the factory setting, and
they can be changed through the S1 DIP switches, according to the table 5.24.
Table 5.24: Configuration of the DIP-switches for the analog input and output signal type selection
AI1 No function S1.4
OFF: 0 to 10 V (factory setting)
ON: 4 to 20 mA / 0 to 20 mA
OFF
AI2 No function S1.3
OFF: 0 to ±10 V (factory setting)
ON: 4 to 20 mA / 0 to 20 mA
OFF
AO1 No function S1.1
OFF: 4 to 20 mA / 0 to 20 mA
ON: 0 to 10 V (factory setting)
ON
AO2 No function S1.2
OFF: 4 to 20 mA / 0 to 20 mA
ON: 0 to 10 V (factory setting)
ON
The parameters related to AI1, AI2, AO1 and AO2 must also be adjusted according to the DIP switch selection
and the desired values
Wire gauge: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
Maximum tightening torque: 0.5 N.m (4.50 Ibf.in).
The wiring at XC1 must be made with shielded cables and laid separately from other wirings (power, 110 V /
220 V commands, etc.), according to the table 5.25.
Table 5.25: Separation distances between wirings
Minimum Separatin Distance
30 m (100 ft) 10 mm (3.94 in)
> 30 m (100 ft) 25 mm (9.84 in)
The figure 5.38 shows the cable shield connection. Refer to the shield connection example showed in the
figure 5.39.

Relays, contactors and solenoids installed inside the SSW7000 cabinet may generate interferences in the
control circuit. In order to eliminate this effect, RC suppressors must be installed in parallel with the coils in
case of AC power supply, and freewheeling diodes in case of DC power supply.
When the HMI is installed outside the SSW7000 cabinet, its cable must be laid separately from the other
installation cables, distant at least 100 mm (3.94 in) from those cables.
