1 MEASUREMENTS AND INSTALLATION | Measurements in mm (in)
1.1 Models for panel mounting
To be fitted to a panel, with elastic holding flaps.
N.B.
- the thickness of a metal panel must be between 0.8 and 1.5 mm (1/32 and 1/16
in), while that for a plastic panel must be between 0.8 and 3.4 mm (1/32 and
1/8 in)
- the measurements of drilling template must be 107.6 x 72.6 mm (3 15/16 x 2
7/8 in), with rounded corners R 3.0 mm (1/8 in).
1.2 Models for wall mounting
Wall mounting (with bolts and fastening screws) or in the most common flush mounting boxes
(with fastening screws).
1. Unhook the back shell from the front through a screwdriver and the proper seat.
2.1 In case of wall mounting:
2.1.1 Lean the back shell against the wall in a position suitable to get the connecting
cable to pass through the proper opening.
2.1.2 Use the slots of the back shell as template to drill 4 holes having a diameter
suitable to the bolt.
5.0 mm (3/16 in) diameter bolts are suggested.
2.1.3 Insert the bolts in the holes drilled in the wall.
2.1.4 Fasten the back shell at the wall with 4 screws.
Countersunk head screws are suggested.
2.2 In case of flush mounting box, fasten the back shell at the box with 4 screws.
Countersunk head screws are suggested.
3. Make the electrical connection as shown in the section ELECTRICAL CONNECTION with-
out powering up the device.
4. Fasten the front of the device at the back shell.
Remote user interfaces (with INTRABUS or RS-485 port)
1.3 Models for wall mounting with back-slot for in-wall box
Wall mounting in the most common flush mounting boxes (with fastening screws).
1. Unhook the back shell from the front through a screwdriver and the proper seat.
2. Fasten the back shell at the box with 4 screws.
Countersunk head screws are suggested.
3. Make the electrical connection as shown in the section ELECTRICAL CONNECTION with-
out powering up the device.
4. Fasten the front of the device at the back shell.

In compliance with safety regulations, the device must be installed properly to ensure
-
adequate protection from contact with electrical parts. All protective parts must be
fixed in such a way as to need the aid of a tool to remove them.
2 ELECTRICAL CONNECTION
N.B.
- Use cables of an adequate section for the current running through them
- To reduce any electromagnetic interference connect the power cables as far away
as possible from the signal cables and connect to an INTRABUS network by using a
twisted pair.
