Installation

Intended use
The in/output module is operated on the FDnet/C-NET. It
has two inputs/outputs. These can be wired as follows:
– Collective detector lines
– Control lines
– Contact input
An optional housing is available to protect against
environmental influences such as wet or damp.
Installing the in/output module
The in/output module can be installed as follows:
– In the housing FDCH221 (Fig. 5)
– On a top hat rail (Fig. 1)
– On an even surface (Fig. 2)
Installation in housing
NOTICE
Module use in a damp, wet or dusty
environment
Damage to module from dust or jet of water
In damp, wet or dusty environments, fit the

module in a housing FDCH221.
1. Open the housing (Fig. 5).
2. Determine the cable entries in the housing and break
these open.
3. Use two screws to fit the housing on a plane surface
(Fig. 3).
4. Secure the M20 x 1.5 cable glands on the housing and
guide in the cables (Fig. 4).
5. Use two M3 x 12 screws to fit the module in the housing
(Fig. 2).
6. Close the housing with the screws provided (Fig. 5).
Procedure with installation on a top hat rail
NOTICE

environment
Module overheating and damage
A minimum clearance of 1 cm must be

observed between two modules or between
the module and any other boundary.
1. Place two mounting feet in the in/output module.
2. Press the in/output module with the mounting feet
against the top hat rail until it engages (Fig. 1).

A minimum clearance of 1 cm must be

observed between two modules or between
the module and any other boundary.
1. Fix the in/output module with two screws on an even
surface (Fig. 2).

Electric connection

1. Connect the cables to the terminals according to the
connection diagram (Fig. 11). Connect only one wire
per terminal.
2. Every control line must be protected with a separate
fuse, with a rating of max. 1.5 or 2 AT.
3. Connect the monitoring resistors or line terminators
(EOL). These must be connected to the end of the line
(Fig. 6 ... 10).
4. Connect the cables to the module with cable ties (max.
width 2.6 mm).
