1.4 Designated use
The multifunction electrical energy meter is designed to record, display and transmit electrical
measured values in low-voltage systems with a maximum nominal voltage of 500 V L-L (289 V L/
N), power connection via low-voltage current transformer x/5A at a nominal frequency of
45 to 66 Hz. It is suitable for use in single-phase power systems, and in three-phase power systems
with three or four wires.
Among other values, the electrical energy meters measure the voltage, frequency, current, power,
power factor, total harmonic distortion (THD) as well as imported and exported active power and
reactive power..
• The manufacturer accepts no liability for damages resulting from incorrect use or use other than
that designated. It is not permitted to convert or modify the device in any way.

3 Installation
3.1 Incoming acceptance, transport, storage
Compliance with the permitted storage and transportation conditions is mandatory. Precise
specifications are provided in the "Technical data" section (® ä 30).
3.1.1 Incoming acceptance
On receipt of the goods, check the following points:
• Is the packaging or the content damaged?
• Is the delivery complete? Compare the scope of delivery against the information on your order
form.
3.1.2 Transport and storage
Please note the following:
Pack the device so that is protected against impact for storage and transport. The original packaging
provides optimum protection.
3.2 Installation conditions
Measuring devices must be mounted in a dry location at stable ambient temperatures that do not
exceed or drop below the range of –10 to 55 °C (14 to 131 °F). There should be minimum tension
from vibrations. If possible, the measuring device should be mounted in such a way that the contrast
of the display is not affected by direct sunlight or strong lighting. The LCD display is optimized for
vertical reading. If the display is read horizontally, lighting conditions can affect the readability of
the display. The measuring device can be installed in any panel cutout according to DIN 96 with a
maximum thickness of up to 5 mm (0.2 in). When mounting, make sure there is sufficient room to
connect cables and wires on all sides of the measuring device. The front of the measuring device is
suitable for use with IP52 protection.
