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.
