Proceed as follows to start the battery storage system:
Step Description
1
Open the screws on the service flat using a PH2 screwdriver.
2
Check whether the NH isolator is equipped with correct (see section 4.5) NH fuses and put into operation
correctly.
3
Check the connections of the DC power cable (+, -) and the CAN communication cable of the battery inverter.
4
Actuate the push button through a short (longer than 1 second) push.
A clicking sound must be heard.
5
Check the LED status of the battery storage system.

The green LED flashes quickly (every 150 msec): The pre-charging path is activated and charges the
capacitors of the inverter. (The pre-charging time depends on the type and number of connected inverters.
The pre-charging time can take from 30 seconds to 2 minutes)

For slave batteries: The green LED flashes slowly (every 1 second): The battery is active and waits for the
switch-on signal of the master battery.

Both LEDs flashes slowly (every 1 second): The battery is active and waits for communication through the
inverter.
The battery switches off automatically after 20 minutes if there is no communication between the battery
and the inverter.
Additional information regarding the LED flashing patterns is given in the Pilot lamps section,
page 95.
