42 Equipment Manual, 12/2019, L1V30415167B-03
Voltage input conductors may be damaged.
The fuses in the voltage measuring inputs are only used for cable protection. Selection of
the fuse depends on the supply cable dimensioning. All commercially available fuses and
automatic circuit breakers up to 16 A (C) or 20 A (B) can be used. The relevant applicable
regulations must be complied with in selecting the fuse.
Voltage input conductors must be protected.
Take the maximum possible ambient temperature into account when selecting the
connecting cables.
The cables must be suitable for operation at a temperature that is 20 °C higher than the
maximum ambient temperature.
Note
Only qualified personnel are allowed to install, commission or service this device.
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 during commissioning
or testing of the device.
The secondary connections of intermediate current transformers must be short-circuited
at the transformers before the current feeder cables to the device are interrupted.
Check the polarity and the phase assignment of the instrument transformers.
Before connecting the device, make sure that the line voltage matches the specifications
on the rating plate.
Before you start commissioning the device, check that all connections are correct.
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.
