4 Connections and settings
4.1 Connecting inputs
4.1.1 DC supply (battery)
The Plena Easy Line Mixer has a 24 VDC input
(terminal screw). This input can be used in mobile
applications, such as boats where 120 or 230 VAC is not
available or in applications that must continue to
operate in case of a power failure.
When a 24 VDC battery is connected (typically
consisting of two 12 VDC lead-acid batteries in series),
the unit will operate on the supplied DC voltage.
Caution
The connection cable must have an in-line fuse.
Use the type of fuse shown in the following
figure.
Caution
Make sure the unit is grounded.
Note
If the backup power system has to comply to the
EN54-4 standard or similar standards for
backup power and charging speeds, Bosch
recommends the PLN-24CH10. The PLN-
24CH10 is a dedicated battery charger and
power supply that is fully EN54-4 compliant.
