SAFETY
This device was built and tested in accordance with the enclosed EU certifi cate of conformity
and left the factory in a condition fullfi lling all requisite safety regulations. To ensure that this
condition is maintained and to ensure hazard-free operation, the user must observe all in-
structions, warnings and warning notes.

Attention Earthing!
1. The device is only allowed to be operated in the operational status and in systems as
stated by the manufacturer (attention is to be paid to adequate ventilation). The following
applies: IP protection class 2X, degree of soiling 2, overvoltage category 2, only for use
indoors, operation at up to 2000 m above sea level.
Outdoor use is only permissible if the
Outdoor use is only permissible if the
measuring instrument is protected from rain and humidity.
measuring instrument is protected from rain and humidity. The device is only allowed to be
operated on supply grids that are protected with fuses with a maximum rating of 16 A. If
not otherwise stated in the data sheet, a tolerance of ± 10 % applies to the nominal mains
voltage and a tolerance of ± 5 % to the nominal mains frequency.
2. In case of measurements in circuits with voltages Ueff > 30 V, precautions must be taken
using suitable measures to ensure that any hazard is excluded (e.g. suitable measuring
equipment, fuse protection, current limiting, isolation, insulation, etc.).
3. If a device is installed in a fi xed position, the connection between the on-site earth con-
ductor connection and the device‘s earth conductor is to be made before any other con-
nections are made. Installation and connection should only be performed by trained elec-
tricians.
4. If devices in a fi xed installation do not have a fuse, circuit breaker or similar protective de-
vice, the supply circuit must be fused so that device and user are adequately protected.
