Wiring the terminal strip in compliance with EMC
● If you use shielded cables, then you must connect the shield to the mounting plate of the
control cabinet or with the shield support of the inverter through a good electrical
connection and a large surface area.
Further information about EMC-compliant wiring is available on the Internet:

Monitoring the temperature of the braking resistor

Danger to life due to fire spreading because of an unsuitable or improperly installed braking
resistor
Using an unsuitable or improperly installed braking resistor can cause fires and smoke to
develop. Fire and smoke development can cause severe personal injury or material
damage.
• Only use braking resistors that are approved for the inverter.
• Install the braking resistor in accordance with regulations.
• Monitor the temperature of the braking resistor.
