Chapter 15 Maintenance
If the status LED flashes red twice every 5 seconds, the power supply unit is faulty. Possible reasons for this
include a broken cable, short circuit or defective cells. In this case, the used power supply unit must be
replaced with a new one.
Note:
Rechargeable batteries are wear parts that lose capacity over time. The capacity is also reduced at high
or low ambient temperatures and under intensive use.
Note:
Ensure that power supply units, especially ones with integrated energy store (rechargeable
battery or battery), are disposed of in line with environmental requirements. Power supply units with
depleted rechargeable battery or battery can be returned to the manufacturer or handed in at suitable
collection points.
15.3 Power supply units with integrated energy store
While power supply units with integrated batteries (e.g. PSU713 BP ) are intended for single use and must be
disposed of accordingly after depletion, power supply units with integrated rechargeable batteries (e.g.
AP ) can be recharged and used again and again. However, the service life of rechargeable
batteries is not indefinite. In addition to regular servicing and maintenance, its service life is also dependent on
the frequency of use and the operating and storage conditions.
