Table 10-46 Optional external EMC Filter terminal data
10.5.2 Varistors
AC line voltage transients can typically be caused by the switching of large items of plant, or by lightening strikes on another part of the supply
network. If these transients are not suppressed, they can cause damage to the insulation of the Regen inductors, or to the Regen drive electronics.
Varistors should be fitted after the supply fuses and before the EMC filter as shown in the following.
Table 10-47 Varistors
Suitable DIN rail mounted surge protectors are also available from CITEL (DS40 series).
10.6 Combined Regen input filters (combi filter)
Table 10-48 Combi filter selection
* Output current derating must be applied based on Regen inductor and combi filter capability.
