6. Maintenance, warranty and
service.
6.1. Basic maintenance guide.
The main guidelines for a correct maintenance are similar to the
ones that are applying our Service and Technical Support in the
Preventive maintenance modality (see section 6.5).
6.2. Battery maintenance.
•
Pay attention to the safety instructions regarding battery and
the stated in section 1.2.3.3.
•
The SPS from SOHO+ series only requires a minimum main-
tenance. The used battery in the standard models is lead
acid, sealed, VRLA and maintenance free. These models
require a minimum of reparations. The only requirement
is to charge the SPS regularly, in order to prolong the bat-
tery lifetime. Meanwhile, it is connected to the power supply,
never mind if the SPS is ON or OFF, it will keep the batteries
charged and will give protection against overcharging and
undercharging.
•
The SPS has to be charged once, every 4 or 6 months if it
has not been used for long time.
•
In hot areas, battery has to be charged every 2 months. The
charging time has to be 12 hours as minimum.
•
Under normal conditions, the battery lifetime is from 3 to 5
years 25º C. In case that the battery was not in good condi-
tions, it has to be replaced before. This replacement has to
be done by qualified staff.
•
Always replace them with the same quantity and type.
•
Do not replace one battery only. All batteries have to be re-
placed at the same time and following the instructions of the
manufacturer.
•
Usually, the batteries should be charged and discharged
every 4 or 6 months. The charging would be started after shut-
down the SPS due to a low battery (discharging). Charging
time for standard SPS should be 12 hours as minimum.
6.2.1. Notes for installing and replacing the
batteries.
•
If it is needed to replace the connection of any wire, purchase
original parts through authorised distributors or service cen-
tres in order to avoid overheating and sparks with fire risk
because the size is not enough.
•
Do not short the + and - poles of the batteries, there is risk of
fire or electrocution.
•
Be sure that there is no voltage before touching the batteries.
Battery circuit is not isolated from the input. Hazardous volt-
ages can be found between the battery and earth terminals
•
Although the input circuit breaker the switchgear panel is
turned off, the internal parts of the SPS are still connected to
the batteries, so there are hazardous voltages inside.
Therefore, before doing any reparation or maintenance task,
the internal battery fuses have to be removed and/or the in-
terlink connections between them and the SPS.
•
Batteries have hazardous voltages. The battery maintenance
and replacement have to be done by qualified personnel and
familiarised with them. Nobody else can manipulate them.
6.3. SPS troubleshooting guide.
