Connection of current sensor
Direct the three phases leading from the main fuse to the consumer through the
n
current sensor.
Connect the 6-conductor control cable of the inverter according to the
n
connection plan. The control cable may have a wire cross-section of 0.75 mm² to
2.5 mm² and a maximum length of 20 m.
The length of stripped insulation is 8-9 mm.
Install the inverter cover and screw it tight (5 Nm).
n
Switch on fuses again.
n
Switch on the inverter.
n
Activate the current sensor in the inverter under the menu point
n
"Settings > Hardware settings > Current sensor position".
To this purpose, choose the corresponding mode.
0 - no current sensor installed
1 - current sensor position for measurement of building consumption (standard)
2 - current sensor position for measurement of grid feed-in
(possible with PIKO BA)
The current sensor is connected.

IMPORTANT INFORMATION
When carrying out the three phases through the current sensor, it
is imperative that the following points are observed:
n It must be ensured that the phase sequence (L1, L2, L3) through
the current sensor agrees with the phase sequence at the
inverter and the sensor connections.
