If you disengage plug connections while the equipment is under power, this may result in fatal accidents or severe personal injury.
• Do not engage or disengage any connecting elements while the product is under power.
WARNING: Risk of injury from damaged or worn components!
Safety functions can fail if damaged or worn components are installed, which can result in death or serious injury.
• Do not use any damaged or worn components.
• In case of replacement, use new screws, spring pins and nuts.
WARNING: Risk of injury due to improper assembly work!
Safety functions can fail if assembly is performed incorrectly, which can result in death or serious injury.
• Further assembly requirements must be defined by the machine manufacturer.
• Note the machine manufacturer’s assembly requirements.
• After assembly, perform an acceptance test according to the machine manufacturer’s requirements.
WARNING: Moving machine parts!
There is a risk of injury due to moving machine parts depending on the installation location and application.
• Observe all of the machine manufacturer’s notes on working on the machine, e.g., always disconnect the machine from the power supply.
WARNING: Hot surface due to high operating temperatures!
Serious burns and skin injuries can be caused by touching the surface of the encoder.
• Never touch the encoder, unless it has cooled down completely.

How do I mount the HEIDENHAIN ERN 1023 variant without a permanently attached cable?
1. Ensure the setscrews do not protrude into the hole.
2. Tighten the setscrews (2x M3).
3. Place the encoder on the machine shaft.
4. Tighten the four screws (4x M3) and the four washers with the specified torque of Md = 1 Nm ± 0.1 Nm to fasten the stator coupling.
5. Tighten the setscrews of the shaft (2x Ø1.5) with the specified torque of Md = 0.6 Nm ± 0.1 Nm.
6. NOTICE: Tensile forces on the wires of the cable assembly can cause damage. Use the provided mounting aid and set it on the connector.
7. Insert the connector.
