FAQ
Are the switchboards backed up with batteries?
No. Batteries are not part of the switchboard and no batteries can be ordered in our range.
Can I use 1 pc 12V battery in a backed up switchboard?
No. Our back-up switchboards include a 48 VDC back-up power supply that is used to power PoE powered switches.
How to connect 4pcs 12 VDC batteries to each other?
The back-up switchboards of the OH series with PBx power supplies require 4pcs of 12V batteries connected in series.
