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.

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 A43/A44 User Manual.
