2. Safety and operating instructions
Intended use
The encoder is a precision measuring device that is used to record positions and speeds. It provides
measuring values as electronic output signals for the subsequently connected device. It must not be used
for any other purpose. Unless this product is specially labeled, it may not be used for operation in
potentially explosive environments.
Make sure by appropriate safety measures, that in case of error or failure of the encoder, no danger to
persons or damage to the system or operating facilities occurs.
Personnel qualification
Installation and assembly of this product may be performed only by a person qualified in electronics and
precision mechanics.
Maintenance
The encoder is maintenance-free and must not be opened up nor mechanically or electronically modified.
Opening up the encoder can lead to injury.
Disposal
The encoder contains electronic components. At its disposal, local environmental guidelines must be
followed.
Mounting
Solid shaft: Do not connect encoder shaft and drive shaft rigidly. Connect drive and encoder shaft with a
suitable coupling.
Hollow shaft: Open clamping ring completely before mounting the encoder. Foreign objects must be kept
at a sufficient distance from the stator coupling. The stator coupling is not allowed to have any contact to
the encoder or the machine except at the mounting points.
Electrical commissioning
Do not proceed any electrical modifications at the encoder.
Do not proceed any wiring work while encoder is live.
Do not remove or plug on connector whilst under power supply.
Ensure that the entire system is installed in line with EMC/EMI requirements. Operating environment and
wiring have an impact on the electromagnetic compatibility of the encoder. Install encoder and supply
cables separately or far away from sources with high emitted interference (frequency converters,
contactors, etc.).
When working with consumers with high emitted interference provide separate encoder supply voltage.
Completely shield encoder housing and connecting cables.
Connect encoder to protective earth (PE) using shielded cables. The braided shield must be connected to
the cable gland or connector. Ideally, aim at dual connection to protective earth (PE), i.e. housing by
mechanical assembly and cable shield by the downstream devices.
Supplementary information
The present manual is intended as a supplement to already existing documentation (e.g. catalogues, data
sheets or mounting instructions).

3. Commissioning
3.1. Mechanical mounting
Shaft encoders
Mount the encoder using the mounting holes in the encoder flange and fitting screws. Observe thread
diameter and depth.
There is an alternative mounting option in any angular position by eccentric fixings available as an
accessory.
Connect drive shaft and encoder shaft by using an appropriate coupling. The shaft ends must not touch
each other. The coupling must compensate temperature and mechanical tolerances. Observe the
maximum permitted axial or radial shaft load. For appropriate couplings please refer to accessories.
Tighten the mounting screws firmly.
Hollow shaft encoders
Mounting by clamping ring
Prior to mounting the encoder open the clamping ring completely. Push encoder onto the drive shaft and
tighten the clamping ring firmly.
Adjusting element with rubber buffer
Push the encoder onto the drive shaft and insert the cylindrical pin into the adjusting element (customer-
mounted) and the rubber buffer.
Spring washer
Fasten the spring washer at the mounting holes of the encoder housing using screws. Push the encoder
onto the drive shaft and mount the spring washer to the contact surface.
3.2. Electrical connection
3.2.1. Cabling
EtherNet/IP utilizes Fast Ethernet cables (100 Mbit/s, Cat. 5).

Baumer_EAx_EtherNetIP_EN_MNL 9/81 www.baumer.com
02.20
3.2.2. Connecting
The encoder provides three M12 flange connectors.
Two M12 flange connectors (D-coding, according IEC 61076-2-101) named “Port 1” and “Port 2” (see below)
serve for the connection.
For voltage supply use an A-coded M12 connector only.
The D-coded M12 connector “Port 1” and “Port 2“ may only be used to connect the encoder to the
EtherNet/IP network.
Seal up any unused M12 connector using a screw cap (included in the delivery).

Preset/Reset button
The encoder may have a screw cap located where M12 connectors and LEDs are located as well. After
removing the screw cap the preset/reset button is visible.
The preset/reset button works in two modes:
Reset Mode: effective in the first 60 seconds after power-on
Pressing the button results in a “Type 1 Reset”. The encoder is reset to factory defaults. For details see
chapter Class Services of the Identity Object.
Caution: Even communication parameters (e.g. IP address) are reset to factory defaults.
Preset Mode: effective after more than 60 seconds after power-on
Pressing the button activates a preset with a value defined in Instance Attribute 107 - Preset Request Value
of the Position Sensor Object (value is 0 by default). The contained position value will be interpreted as
absolute value.
In order to perform a preset/reset the push button must be pressed for a duration of at least three seconds
(LEDs blinking red) and longest five seconds. The button has to be released when the LEDs change from
red blinking to green blinking.
