Warning – Working with high voltage is potentially lethal. Persons subjected to high voltage may suffer cardiac arrest, burn injuries, or other severe injuries. To avoid such injuries, make sure to disconnect the power supply before you start the installation. Electrical equipment should only be installed, accessed, serviced and maintained by qualified electrical personnel.
Warning – For safety reasons it is recommended that the equipment is
installed in a way that makes it impossible to reach or touch the terminal
blocks by accident.
The best way to make a safe installation is to install the unit in an
enclosure. Further, access to the equipment should be limited through use of
lock and key, controlled by qualified electrical personnel.
Warning – The meters must always be protected by fuses on the incoming side. In order to allow for maintenance of transformer rated meters, it is recommended that there should be a short circuiting device installed near the meter. Do not operate the equipment outside the specified technical data.
Installation Requirements
To comply with the protection requirements the meter must be mounted in protection class IP 51 enclosures, or better, according to IEC 60259.
Troubleshooting
If any of the following icons appear in the display after the installation has been completed and power has been connected to the meter, refer to the B21/B23/B24 User Manual for detailed information
Service and Maintenance
The meter contains no parts that can be repaired or exchanged. A broken meter must be replaced. If the meter needs to be cleaned, use a lightly moistened cloth and a mild detergent to wipe i
Caution – Be careful that no liquid gets into the meter since it may damage the equipment.
