Connection of Power Sensor
Following tasks to start the Power Sensor
•
4.1 Disconnecting from voltage
•
4.2 Power Sensor mounting
•
4.3 Split core sensors installation
•
4.4 Connection to Power Storage DC
•
4.5 Connection to Power Storage AC
•
4.6 Initiation and App configuration
The Power Sensor may only be used with the supplied communication cable or another
Ethernet cable with the following properties (max. length: 30m, at least CAT 5 and at least
AWG 22).
Disconnecting Power Storage from voltage
Risk of death or serious injury due to electric shock!
When the inverter is connected to the utility grid (AC voltage source) and/or to a PV
array which is exposed to sunlight (DC voltage source), high voltage is present within
the inverter components which can cause fatal electric shocks.
•
Any work which involves wiring, connecting or opening the inverter or the
battery housing has to be performed by qualified personnel.
•
Make sure other persons keep away from cables and inner inverter parts.
Risk of death or serious injury due to electric arc!
When the inverter is connected to a PV array which is exposed to sunlight (DC
voltage source), high voltage is present within the cables and inverter components
which can cause electric arcs when DC plugs are disconnected under load.
Electric arcs can cause fatal electric shocks or burns.
Disconnection procedure:
Step
Description
1
Locate DC switch of inverter and turn to “0” position [only Power Storage DC].
2
Locate ON/OFF switch of Battery and switch to ”0” position.
3
Locate and switch off circuit breaker, main breaker or fuse for disconnecting inverter from utility grid.
4
Wait 10 minutes until capacitors have discharged and check the voltage.
