Installation

For information about how to mount and install the equipment, follow

the instructions in the Installation Guide at the end of this manual.

E Warning – Working with high voltage is potentially lethal. Per-

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.

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 VC appear in the display after the

installation has been completed and power has been connected to the

meter, refer to the B21 User Manual for detailed information.
