Application with current transformer
CAUTION
Possible danger to life:
In case a current transformer is used for current measuring, the phase potential will be
on its secondary winding. This results in a hazardous voltage at the transformer.
•
Take care for an appropriate protection device (e.g. covering).
•
In case further measuring devices shall be placed within the current measuring circuit
the relevant standards must be regarded.
CAUTION
Hazardous Voltage on open circuit path!
•
Never use a transformer in no load condition.
•
Always connect the transformer with the power measurement module before you start
to operate the transformer.
•
Never unlock the connector frame of the module during operation with a transformer.
