Installation Requirements
3.1
Installation site conditions
The installation site must meet the requirements of the meter’s
protection class (IP54) and the operating temperature range (-20 °C
... +70 °C). There must be no corrosive gases or dust on the
installation site.
3.2
Installation place
The E700 can be installed on the meter frames corresponding to the
DIN or ERMI specifications or directly to an unflammable wall.
The place must not be so narrow or closed that the cooling of the
meter is inhibited.
3.3
Voltage systems
3.3.1
Electricity network
Check that the voltage marked to the meter nameplate is the same
as the voltage used on site. Use the wires and cables designed for
the used voltage and current.
3.3.2
Outputs
There are two types of outputs. Check that the output corresponds
to the used voltage.
3.3.2.1
Pulse outputs (option card)
S0-connections are SELV-circuits (Safety Extra Low Voltage). The
measuring voltage that the E700 feeds to the S0-connections is 18 -
27 VDC. Low-voltage wires can be used. Do not connect pulse
outputs to ground.
When you connect the S0 outputs to other device’s inputs, make
sure that the inputs are filtered concerning high frequency
interference.
3.3.2.2
Semiconductor outputs (option card)
The relay outputs are high voltage connections: 230 V, 100 mA.
Use the wires and cables designed for the used voltage and current
