(max. 2,5 mm², which is the maximum size of the connector).
Note!
All relays must have the same supply voltage!
3.3.3
Inputs
There are two types of inputs. Make sure that the input corresponds
to the used voltage.
3.3.3.1
Pulse and status inputs 18–27 VDC (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.
3.3.3.2
Pulse and status inputs 230 V (option card)
These inputs are high-voltage connections: 230 V, 100 mA. Use the
wires and cables designed for the used voltage and current (max.
2,5 mm², which is the maximum size of the connector.
Note!
The 18 - 27 VDC is the maximum voltage for S0-inputs and
outputs. Do not use higher voltage.
Note!
During the installation, keep the low-voltage wires away from
the 230 V wires. If you do not use a pre-fabricated wire set,
bundle the different types of wires into separate groups starting
immediately from the terminal.
Note!
If an input device does not meet the SELV requirements (for
example, a transistor output that is not opto-insulated), all
circuits become immediately 230 V circuits. In such case, use
the 230 V wires.

Meter configuration
Use the E700UI software to configure the meter. Refer to the E700
Product Description and E700UI Manual for further information.
An E700 meter can also be configured at the Enermet factory. In
such case, check the meter’s date and time during the installation.
