Frequency inverters have been developed for operation in industrial environments. It may be
necessary to implement an optional mains choke if required by the system and/or the application.
These chokes must be matched to the power range of the frequency inverter and the mains supply.
Benefits
Using an optional choke will
• Minimise mains feedback and mains current surges
• Significantly reduce the current harmonics
• Restrict start-up and peak current
• Reduce the apparent power and charge currents in the link circuit
• Improve cosφ
Application
The mains choke is implemented upstream of the frequency inverter and limits the input current to
approximately the output current level of the SK 5xxP. These mains chokes are UL certified and
should always be installed in the control cabinet due to their protection class (IP00). Optional
connection occurs with a connection cable to be supplied and with screw terminals at the mains choke
and at the frequency inverter.

DANGER!
Danger of electric shock
The frequency inverter continues to carry hazardous voltages for up to 5 minutes after it was switched
off.
• Work must not be carried out unless the device has been disconnected from the voltage and at
least 5 minutes have elapsed since the mains was switched off!

CAUTION
Danger of burns
The module and all other metal components can heat up to temperatures above 70 °C.
• Sufficient cooling time must be allowed for when working on the components in order to avoid
injuries (local burns) to parts of the body coming into contact with the components.
• In order to avoid damage to neighbouring objects, sufficient clearance must be maintained during
installation.

It only is allowed for qualified electricians to install and commission the module. An electrician is a
person who, because of their technical training and experience, has sufficient knowledge relating to
• switching on, switching off, isolating, earthing and marking power circuits and devices,
• proper maintenance and use of protective devices in accordance with defined safety standards.

The mains choke is mounted directly on the mounting surface (rear wall) of a control cabinet.
Appropriate mounting holes are provided for this purpose.
Information
The mains choke is intended for installation in electrical systems or machines. To protect the mains
choke from overheating, it requires sufficient ventilation.
When mounting chokes, heed the information in sections "Installation position" and "Clearances".
