sons 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 instal-
lation.

Electrical equipment should only be installed, accessed, ser-
viced and maintained by qualified electrical personnel.
E 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 lim-
ited through use of lock and key, controlled by qualified electri-
cal personnel.
W 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.
Meters with wireless communication should not be installed closer
than 20 cm from people.
Troubleshooting
If any of the following icons W VCappear in the display after the
installation has been completed and power has been connected to the
meter, refer to the B23/B24 User Manual for detailed information.

Configuration
To configure the meter and change the default settings, follow the in-
structions in the Configuration Guide at the end of this manual.
Default Settings
The following table lists the default settings of the meter that normally
needs to be changed. Check the settings to see if any of them needs to
be changed.
N Note – For all other settings, including communication default
settings, refer to the B23/B24 User Manual.
Service and Maintenance
The meter contains no parts that can be repaired or exchanged. A bro-
ken meter must be replaced.
If the meter needs to be cleaned, use a lightly moistened cloth and a
mild detergent to wipe it.
C Caution – Be careful that no liquid gets into the meter since it
may damage the equipment.
