F.A.Q. Technical

Frequent questions:

• Upon start-up, can the secure power supply be started up only with its battery?

No, it is essential to initialise it with the mains

• Can 2 power supplies be wired redundantly?

Yes via a redundancy unit.
No (forbidden) for the AES secure power supplies and SONaes (no longer compliant)

• How do I connect batteries with 2 redundant power supplies?

Do not connect the battery (+ and -) to a single charger. To have the same impedance on the circuit the cable must be the same length for each pole and the battery + must be connected to one charger and the battery – to the other charger

• How do I define my battery cable sections?
