Connection of current sensor
The current sensor is installed on a top-hat rail in the meter box or the main
distributor.
To this purpose, carry out the following steps:
De-energise the home network and inverters
n
To this purpose, read the chapter "De-energise inverters" in the operating manual
of the inverter.
Mount the current sensor professionally on the top-hat rail of an electrical cabinet
n
or current distributor. Only the sensor approved for the inverter may be used.
Integrate the current sensor into the system depending upon the application
n
(mode) and connect professionally.
Open the inverter cover.
n
Properly lay the cable from the inverter into the electrical cabinet.

DANGER
RISK OF DEATH DUE TO ELECTRICAL SHOCK AND DISCHARGE!
De-energise the inverter, secure it against being restarted and wait
five minutes so that the capacitors can discharge.
