7.1. Battery
maintenance.
Ŗ
Pay attention to the safety instructions regarding battery and
the stated in section 1.2.3.3.
Ŗ
The UPSs from
SLC TWIN RT
series only requires a
minimum maintenance. 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 UPS regularly, in order to pro-
long the battery lifetime. Meanwhile, it is connected to the
power supply, never mind if the UPS is ON or OFF, it will
keep the batteries charged and will give protection against
overcharging and undercharging.
Ŗ
The UPS has to be charged once, every 4 or 6 months if it
has not been used for long time.
Ŗ
In hot areas, battery has to be charged every 2 months. The
charging time has to be 12 hours as minimum.
Ŗ
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.
Ŗ
Always replace them with the same quantity and type.
Ŗ
Do not replace one battery only. All batteries have to be re-
placed at the same time and following the instructions of the
manufacturer.
Ŗ
Usually, the batteries should be charged and discharged
every 4 or 6 months. The charging would be started after a
UPS shutdown due to a low battery (discharging). Charging
time for standard UPS should be 12 hours as minimum.
7.1.1. Notes for installing and replacing
the batteries.
Ŗ
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.
Ŗ
Do not short the + and - poles of the batteries, there is risk of
fire or electrocution.
Ŗ
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.
Ŗ
Although the input and bypass circuit breaker switches (the
last one in 4 to 10kVA models with the respective power
supply mains) are turned off, the internal parts of the UPS
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 UPS.
Ŗ
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.
7.2. UPS Trouble Shooting guide.
If the UPS doesn't work properly, check the information given
by the LCD of the control panel, according to the models and
power of the equipment. Try to solve the problem by means of

persists, consult with our Service and Technical Support S.T.S..
When it is needed to contact with our Service and Technical Sup-
port S.T.S. , provide the following information:
Ŗ
UPS model and serial number.
Ŗ
Date when the problem occurred.
Ŗ
Complete description of the problem, including the infor-
mation given by the led or LCD panel and the status of the
alarms.
Ŗ
Power supply condition, type of load and the level connected
to the UPS, ambient temperature, cooling conditions.
Ŗ
Information of the batteries (capacity and battery quantity), if
the equipment is (B0) or (B1) -with external batteries-.
Ŗ
