Important: (see chapter 4.14.1)
At the time of commissioning of batteries connected in parallel, first switch on the master battery.
1. Check whether the main relay of the master battery is switched on
-> Check via LED flashing speed (see section 5.1) or BMZ service tool (see section 5.2)
2. If the main relay of the master battery is closed, you can now switch on other slave batteries.
If the switch-on sequence for batteries connected in parallel is not followed, it may happen that none of
the batteries allow switching off the main relay.
Switch on the battery storage system using an external voltage source
Proceed as follows to start the battery storage system:
Step Description
1
The external voltage source can be used to switch on the system only if it was not switched off using the push
button (press the push button longer than 10 seconds at a stretch).
2
Connect an external voltage source greater than 36 VDC.
3
The battery detects the external voltage source automatically and switches the operating mode from inactive to
active.
4
If it is switched on in an unauthorised manner, the green LED flashes quickly (100 ms flash cycle)
You must now start the battery using a normal switch-on sequence (by pressing the push button longer than 1
second).
Switch off the battery storage system using a push button
Proceed as follows to switch off the battery storage system:
Step Description
1
Open the screws on the service flat using a PH2 screwdriver.
2
Keep the switch-on button pressed for at least 10 seconds.
3
After approximately 8 seconds, both LEDs start flashing quickly (100 ms flash cycle).
Keep the button pressed for 2 more seconds.
4
The LEDs switch off. The battery storage system is now switched off.
A clicking sound must be heard.
