1. Safety instructions

This description is part of the device. It contains texts and drawings
concerning the correct correct handling of the device and must be
read before installation or use.

Observe the operating instructions. Non-observance of the notes, operation
which is not in accordance with use as prescribed below, wrong installation or
handling can result in serious harm concerning the safety of persons and plant.

These instructions are intended for ”authorised” persons according to EMC and
the low-voltage directives. The device may only be installed, connected and put
into operation by a qualified electrician.

Disconnect the device externally before handling it. If necessary, also disconnect
any independently supplied output load circuits.

If the device is not supplied by the mobile on-bord system (12/24 V battery oper­ation), it must be ensured that the external voltage is generated and supplied ac­cording to the criteria for safety extra-low voltage (SELV) as this voltage is sup­plied without further measures to supply the connected controller, the sensors
and the actuators.

The wiring of all signals in connection with the SELV circuit of the device must al­so comply with the SELV criteria (safety extra-low voltage, safe electrical separa­tion from other electric circuits).
If the supplied SELV voltage has an external connection to ground (SELV becomes
PELV), the responsibility lies with the user and the respective national regulations
for installation must be complied with. All statements in these operating instruc­tions refer to the device the SELV voltage of which is not grounded.

The connection terminals may only be supplied with the signals indicated in the
technical data and/or on the device label and only the approved accessories of
ifm electronic gmbh may be connected.

The device can be operated within a wide temperature range according to the
technical specification indicated below. Due to the additional internal heating the
housing walls can have high perceptible temperatures when touched in hot envi­ronments.

In case of malfunctions or uncertainties please contact the manufacturer. Tamper­ing with the device can lead to serious risks for the safety of persons and plant. It
is not permitted and leads to the exclusion of liability and warranty claims.

Attention

This is a class A installation. It can cause radio interference in domestic areas. In
this case the operator is requested to take appropriate measures.

2. Functions and features

The freely programmable controllers of the ”CabinetController” series are rated
for use under difficult conditions (e.g. extended temperature range, strong vibra­tion, intensive EMC interference). They are suitable for direct installation in mo­bile vehicles.

By means of the application software, the inputs and outputs can be configured
to adapt to the respective application.

The controllers can be used as CANopen master or intelligent I/O module.

The user is responsible for the safe function of the application programs
which he created himself. If necessary, he must additionally carry out an ap­proval test by corresponding supervisory and test organisations according
to the national regulations.

The controller is not approved for safety tasks in the field of safety of per­sons.

3. Mounting

3.1 Mounting location

The controller is to be mounted in a dry and enclosed environment (e.g. control
panel of the driver’s cab, separate control boxes, etc.).

The housing must not be exposed to any torsion forces or mechanical
stress.

3.2 Fixing

Insert the enclosed tubular rivets from the back of the module in the 4 fixing
holes.

Fix the module using 4 washers and screws.
Tighten the screws alternately crosswise.

Torque: 1.5 Nm
Mounting position: any
Hole dimensions: see back of the controller or Technical data, page 9

3.3 Cooling

As the internal heating of the electronics is conducted away via the housing, en­sure sufficient heat dissipation.
