power sensors for the first time.
Risk of injury due to disregarding safety information
Observe the information on appropriate operating conditions provided in the data sheet
to prevent personal injury or damage to the power sensor. Read and observe the basic
safety instructions provided with the power sensor, in addition to the safety instructions
in the following sections. In particular, do not open the casing of the power sensor.
Risk of electrostatic discharge
Protect the work area against electrostatic discharge to avoid damage to electronic
components in the modules. For details, refer to the general safety instructions.
Risk of instrument damage due to inappropriate operating conditions
An unsuitable operating site or test setup can damage the power sensor and to con-
nected devices. Before switching on the power sensor, observe the information on
appropriate operating conditions provided in the data sheet. In particular, ensure the
following:
●
The power sensor is dry and shows no sign of condensation.
●
The power sensor is connected as described in the following sections.
●
The ambient temperature does not exceed the range specified in the data sheet.
●
Signal levels at the input connectors are all within the specified ranges.
●
Signal outputs are correctly connected and are not overloaded.
4.1 EMI Suppression
Electromagnetic interference (EMI) can affect the measurement results.
To suppress generated electromagnetic interference:
●
Use suitable shielded cables of high quality. For example, use double-shielded RF
cables.
●
Always terminate open cable ends.
●
Note the EMC classification in the data sheet.
