2 Safety instructions
2.1 General
These instructions are part of the device� They contain texts and figures
concerning the correct handling of the device and must be read before
installation or use�
Observe the operating instructions� Non-observance of the instructions,
operation which is not in accordance with use as prescribed below,
wrong installation or incorrect handling can seriously affect the safety of
operators and machinery�
2.2 Target group
These instructions are intended for authorised persons according to
the EMC and low-voltage directives� The device must only be installed,
connected and put into operation by a qualified electrician�
2.3 Electrical connection
Disconnect the unit externally before handling it� If necessary, also
disconnect any independently supplied output load circuits�
If the device is not supplied by the mobile on-board 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 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 isolation from other electric circuits)�
If the supplied SELV voltage is externally grounded (SELV becomes
PELV), the responsibility lies with the user and the respective national

5
UK
installation regulations must be complied with� All statements in this
document 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 may be connected�
2.4 Tampering with the device
In case of malfunctions or uncertainties please contact the manufacturer�
Any tampering with the device can seriously affect the safety of operators
and machinery� This is not permitted and leads to the exclusion of any
liability and warranty claims�

3 Functions and features
The camera serves for monitoring of areas outside of the field of view in
mobile machines and utility vehicles� The connection and the visualisation
of the images are made via dialogue modules with graphics capabilities�
The camera works with a nested PAL25 fps 720H x 576V (active
720 x 480) video signal and permanently provides images to the
connected dialogue module�
Applications are for example:
• Rear area or blind spot monitoring for municipal vehicles
• Machine monitoring in construction machinery
• Rear view camera on vehicles

4 Installation
4.1 Mounting accessory
►The unit is supplied with an E2M210 universal mounting clamp�
Other mounting accessories are available as alternative
�
You can find more information about the available accessories at:
www.ifm.com→Newsearch→O2M200→Accessories
or directly
www.ifm.com→Newsearch→e.g.E2M210
4.2 Mounting dimensions

max� tightening torque of 0�8���1 Nm�
6� Provide for a borehole of d = 19 mm for the cable entry in the cabin / termi-
nal chamber� Insert the camera cable and seal the cable entry with the freely
positionable rubber grommet (1)�
The minimum bending radius of the camera cable of 50 mm must be
observed�

►To avoid adverse effects on the image detection, avoid installation
in heavily polluting areas of the machine (e�g� splashing water, tyre
abrasion, etc�)�

►Avoid installation in niches, observe the angle of aperture of the lens�
►Avoid back light�
►Do not position lighting elements directly facing the camera lens�
►Mount the device in such a way that the cables / connectors are
connected from below�
►The connected cables must be provided with a strain relief�
►Observe the minimum bending radius of 50 mm of the camera cable�
