Usage area

Link circuit choke to im prove mains quality. Due to its principle of oper ation, distortions of the mains
voltage caused by the fr equency inverter are c onsiderably reduced b y the use of a link circuit chok e.
The harmonic com ponent of the current is reduced to approx. 40% and the power factor (lam bda) is
increased. The module is installed in the immediate vicinity of the frequency inverter.

Installation

DANGER!

Do not work on live components (observe the 5 safety rules!)
Failure to comply with this will result in serious or fatal injuries in case of contact.

Electric shock

5 safety rules:

• Disconnect

• Secure against switching on

• Check for no voltage

• Earth and short circuit

• Cover or guard adjacent live components

CAUTION

When in operation, the surface temperature of the device may reach temperatures of approx. 105 °C. To avoid
protective devices must be provided.

Danger of burns

Installation l ocation Inside a control cabinet near to the frequency inerter. Note the load bearing

capacity of the mounting plate!

example, be by use of the enclosed shrink tube.
