Circuit proposal for controlling the auxiliary contactor from within the drive
The following circuit, for example, can be used if the auxiliary contactor is to be controlled
from within the drive. The "Operation" message is then no longer available for other
purposes.

Note
Additional protective conductor
If 115 V AC is applied to the relay outputs, the customer terminal module must also be
grounded via a #14 AWG (2.5 mm²) ground conductor.

Line filter monitoring (option L40)
Description
The line filter monitoring option is used for monitoring the filter in the Active Interface Module
for effectiveness against harmonic effects on the system.
By measuring the current and voltage in the Active Interface Module, the capacitance of the
filter capacitors of the integrated filter is continuously calculated and compared with the
installed nominal capacitance.
Alarm A06250 is triggered if the calculated capacitance is higher than the set comparison
threshold.
