7.2.3 Attaching surge killers to control equipment
If communication errors happen in synch with the on/off signals from certain control equipment (referred to
as "load" hereafter) such as no fuse breakers, electromagnetic contactors, relays, solenoid valves, and
induction motors, surge noise interference is suspected.
If this problem happens, keep the ground cable and communication cable away from the load.
If that is not possible, an installation of a surge killer will help reduce noise interference.
Place the surge killer as close to the load as possible.
