Or by connecting special I-LBA Low Battery Adaptor module:
The I-LBA module ensures min. 350ms voltage dip under following conditions:
Voltage before dip is 12V and after 350ms the voltage recovers to min. allowed voltage 5V.

The I-LBA enables controller operation from 5VDC (for 10 to 30 sec).
The wiring resistance from battery should be up to 0.1 Ohm for I-LBA proper functio

Do not connect binary outputs directly to DC relays without protection diodes, even if they are not
connected directly to controller outputs.
Grounding
To ensure proper function:
•
Use as short as possible cable to the grounding point on the switchboard
•
Use cable min. 2,5mm
