Power Supply
The functional units described are supplied by a power supply (PS) with the adequate power in the different
voltage levels. Transient voltage dips may occur if the auxiliary voltage supply system becomes short-circuited.
Usually, they are bridged by a capacitor storage (see also the Section 4 Technical Data).
A buffer battery is located behind the lower front cover.
