4 Installation and commisioning

4.2 Connect the brake chopper

CAUTION

EMC: Interference and risk of injury from electromagnetic alternating fields!

Current-carrying cables – particularly around supply cables – produce electromagnetic
alternating fields.

These can interfere with the product and other devices and lead to uncontrolled behavior and
injuries.

►

Connect the product to earth over a short distance using the PE conductor.

►

Perform a risk assessment for the entire machine/system to identify possible risks due to

electromagnetic interference and initiate suitable protection measures if necessary.

NOTICE

Damage to the product!

Changing the wiring during operation may damage the connectors.

►

Only change the wiring in a de-energized state. After switching off, wait until the capacitors

have discharged.

Connect the brake chopper in parallel to the power supply, as shown in the following figure.
