Fig. 23: Connecting voltage supply, e.g. to
an OTT PCU 12 power control unit. The OTT
PCU 12 is the OTT standard voltage supply.
Alternatively to PCU terminal 1 (load dis-
connect at a battery voltage of ≤ 7.5 V),
terminal 2 can also be used (load discon-
nect at a battery voltage of < 10.5 V).
Please note: A battery must always be con-
nected to the OTT PCU 12!
