8. Maintenance
The power supply requires no specific maintenance; however, sealed lead acid batteries have a limited lifespan and
should be checked periodically in accordance with the manufacturer’s recommendations and replaced as recommended
below.
The only replaceable parts are the mains fuses and fuses on the dual power output board RPSM2 on KD25800 models.
Should a fuse fail, the fuse must only be replaced with fuses of the same type as originally fitted. Spare fuses
are supplied in the accessory pack. Care must be taken to select the correct one when replacing fuses.
These are as follows:
Mains Input fuse – F5A 250V TD 20mm. (Replace only with fuses of the same type).
KD25800 series RPSM2 fuses- FF very fast acting
12A.
(Replace only with fuses of the same type).
9. Standby batteries
Sealed lead acid batteries have an expected life of 3 to 5 years when operated at an ambient temperature of 20
o
C.
Batteries operating in temperatures higher than 20
o
C will have a significantly reduced life of approximately 50% for
every 10
o
C above 20
o
C.
This must be considered when determining the battery maintenance schedule and batteries consistently operating in
higher ambient temperatures should be replaced more frequently.
Batteries with a manufacturing date older than 6 months are not recommended for use with this equipment.
Sealed lead acid batteries can liberate hydrogen during normal use. The KD25800 and K25800 series of power
supplies have adequate ventilation to allow this hydrogen to disperse normally and safely therefore additional sealing
or mounting inside a sealed enclosure is prohibited.
Batteries contain hazardous substances and must be returned to the supplier or manufacturer for disposal.
Refer to battery manufacturers recommendations for further information.
