B.1.5 Line reactor
The line reactors get hot during operation. Do not touch. Provide adequate clearance and
ventilation.
When operating the larger line reactors in an environment with a surrounding air
temperature in excess of 40° C, the wiring of the terminal connections must be
accomplished using 75° C copper wire only.
Risk of equipment damage and electric shocks
Some of the line reactors in the table below have pin crimps for the connection to the
converter's mains terminals.
Use of these pin crimps can cause damage to the equipment and even electric shocks.
For safety reasons, replace the pin crimps using UL/cUL-certified fork crimps or stranded
cables.
The line reactors have a protection rating of IP20 in accordance with EN 60529 and are
designed to be mounted inside a cabinet.
Functionality
The line reactors are used to smooth voltage peaks or to bridge commutating dips. They also
can reduce the effects of harmonics on the converter and the line supply.
The larger line reactors for the 230 V variants of converters have side mounting brackets to
allow side-by-side mounting (see diagram below).
