Combi filters listed in Table 3-23 Combi filter selection on page 39 are equipped with an internal thermal switch to prevent the EMC filter
inductor from overheating. The thermal switch must be configured to open the main supply contactor in the event of a thermal overload.
Regen inverter output current derating must be applied where necessary based on Regen inductor and combi filter capability.
Models affected are denoted with * in Table 3-23 Combi filter selection on page 39. Combi filters listed in Table 3-23 are suitable for use in
systems with less than 2 % THD
v
on the grid.
