Turn off and lock out all power supplying this device before working on this device.
Note
The following tasks are partly carried out when hazardous voltage is present. For this
reason, they must only be carried out by qualified personnel who are familiar with and follow
the safety regulations and cautionary measures.
Wear the prescribed protective clothing. Observe the general equipment regulations and
safety regulations for working with high-voltage installations (e.g. DIN VDE, NFPA 70E as
well as national or international regulations).
The limits given in the technical data must not be exceeded even at startup or when testing
the device.
The secondary connections of intermediate current transducers must be short-circuited at
the transducers before the current lines to the device are interrupted.
The polarity and phase assignment of the measuring transducer must be tested.
Before connecting the device, you must check that the system voltage agrees with the
voltage specified on the type plate.
Check that all connections are correctly made before startup.
Ensure the polarity is correct when connecting a DC supply voltage.
Before power is applied to the device for the first time, it must have been located in the
operating area for at least two hours in order to reach temperature balance and avoid
humidity and condensation.
Condensation on the device is not permissible during operation.
