Technical data:
- The green terminals are male connectors (pitch 3.5 or 5 mm), the correspond-
ent female connectors have screw or spring terminals for connecting the wires;
- Made with self extinguishing material as required by UL94 V0 standard;
- Overvoltage cathegory/pollution degree II/2;
- Max. load current/section 8A/2.5mm² at 65°C;
- Test pulse voltage: 4 kVp.
m
Make sure that the overall current absorption (modules and field devices)
matches the power supply.
m
In order to avoid excessive voltage drops, install the most power consum-
ing modules closer to the power supply.

Despite 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.
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 power lines and 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 inputs, with the shield
connected to earth at only one side.

Warning!
Whenever a failure or a malfunction of the device may cause dangerous
situations for persons, things or animals, please remember that the plant
must be equipped with additional devices which will guarantee safety.

Mounting position
- Mount the CPU in a 75 x 130 mm
hole;
- In order to help the air ventilation
flow, respect the distances between
the CPUs and walls or other CPUs.

Disposal
The appliance (or the
product) must be
disposed of separately in
compliance with the local
standards in force on
waste disposal.
Mount and remove the CPU
1
Open a 75 x 130 mm hole in the
mounting panel;
2
Insert the CPU into the hole until the
frame rests on the panel;
3
Mount the two red blocks and slide
them until they are in contact with
the panel and hold the CPU in place;
4
To remove the CPU, sconnect the ter-
minals, then remove the red blocks
and invert the mounting sequence.
