How to increase the electromagnetic immunity
For maximum immunity to disturbance use FIL00014 fil-
ter. Install it between the outlet and the power supply,
closest to 24 V power supply.
A good ground connection is required between the filter
case and the earth.
In addition a FIL00013 clamp filter could be placed on the
analogue inputs, outputs and communication cables posi-
tioned close to the device and winding a cable loop in the
clamp filter as illustrated.
