Installation recommendations

•The instruments must be powered from a dedicated

instrumentation power supply.

•It is strongly recommended to apply RC'S FILTERS (noise

suppressor) to contactor coils, solenoids, etc.

•To improve measurement stability, immunity and safety, it is

recommended to use system grounding.
