PSB 9000 2.5 kW Series
3.12.3 Operation as battery charger (source mode)
A power supply (here: PSB 9000 in source mode) can be used as a battery charger, but with some restrictions,
because it misses a battery supervision and a physical separation from the load in form of a relay or contactor,
which is sometimes featured with real battery chargers as a protection.
Following has to be considered:
• No false polarity protection inside! Connecting a battery with false polarity will damage the power supply severely,
even if it isn’t powered.
4. Service and maintenance
4.1 Maintenance / cleaning
The device needs no recurring maintenance. Cleaning may be needed for the internal fans, the frequency of cleanse
is depending on the ambient conditions. The fans serve to cool the components which are heated by the inherent
powerloss.Heavilydirtlledfanscanleadtoinsu󰀩cientairowandthereforetheDCterminalwouldswitcho󰀨
too early due to overheating or possibly lead to defects.
In case there is requirement for such a maintenance, please contact us.
4.2 Fault nding / diagnosis / repair
If the equipment suddenly performs in an unexpected way, which indicates a fault, or it has an obvious defect, this
can’t and must not be repaired by the user. Contact the supplier in case of suspicion and elicit the steps to be taken.
It will then usually be necessary to return the device to the supplier (with or without guarantee). If a return for
checking or repair is to be carried out, ensure that:
• thesupplierhasbeencontactedandit’sclariedhowandwheretheequipmentshouldbesent.
• the device is in fully assembled state and in suitable transport packaging, ideally the original packaging.
• optional extras such as an interface module is included if this is in any way connected to the problem.
• a fault description in as much detail as possible is attached.
• if shipping destination is abroad, the necessary customs papers are attached.
4.2.1 Firmware updates
Firmwareupdatesshouldonlybeinstalledwhentheycaneliminateexistingbugsintherm-
