Use with a contactor
Ameasurement instrument is normally continually supplied.
For a non-continuous supply (load switching), we recommend that you place the
breaking device downstream from the measurement instrument to limit disturbances
on the module inputs.
These disturbances, particularly on inductive loads, may result in early ageing of the
device.
You must also place the measurement instrument at a distance from the breaking
device to limit the risk of disturbance.
