5.5.10.4 Replacement of Power Supply Unit
DANGER
Power supply units should be replaced by authorized service personnel only.
The branch A or B which is to be repaired must be carefully defined.
The replacement instruction focuses on the unregulated power supply units SA16x (a.c.) and
SD150 (d.c.). However the principles are valid for power switch and distribution unit
replacement as well.
Replacing a power supply unit shall always be carried out with highest safety possible.
Basically this means that voltage supply should always be switched off during repair and
installation work. Special provision is made for a system including redundancy where
replacement is urgently needed in a live system.
Before replacing a primary power supply unit, break its mains switch S1 in the power switch
unit (for the actual mains A or B). When the power supply unit is pluggable, unplug the power
cord. Where the power supply installation is fixed also switch off a safety breaker or remove the
actual fuse in the buildings mains installation before working in the power supply circuitry.
