1Open the 2 spring slides on the lower
part of the CPU, clip the upper part of
the module to the rail;
2Rotate the module downwards, then
close the 2 spring slides;
3Switch OFF the Power Supply
Lower the spring slide by inserting a
flat-blade screwdriver as indicated;
4Turn and lift the module upwards to
remove the CPU from the DIN rail.
Dimensions (mm)
Mounting the module
- Mount the module vertically;

Serial Communications Ports
- Connector X10: to connect an
RS232/485 terminal (also for setup
purposes). Through this port, using
the Modbus protocol (master/slave)
or serial ASCII the PLC can connect
a fieldbus network;
- The RS232 cable must be shorter
than 15 m;
- Connector X11: RS485 port to
connect a fieldbus network using
the Modbus protocol (master/
slave) or serial ASCII;
- These two ports can be configured
using the DIP switches on the
right of the X10 connector;
- Isolation from other electronics:
1600 V.

ADespite the fact that the instrument has been designed to work in an
harsh and noisy environment, it is strongly recommended to follow
the following suggestions.
All the wiring must comply with the local regulations.
The supply wiring should be routed away from the power cables. Avoid to use
electromagnetic contactors, power relays and high power motors nearby.
Avoid power units nearby, especially if controlled in phase angle. Keep the low
level sensor input wires away from the power lines and the output cables.
Power lines and output cables must also be at 100 mm (min.) away from the CPU.
If this is not achievable, use shielded cables on the sensor input, with the shield
connected to earth.
AWarning!
Whenever a failure or a malfunction of the device may cause dan-
gerous situations for persons, things or animals, please remember
that the plant must be equipped with additional devices which will
guarantee safety.
