8. MAINTENANCE, WARRANTY AND SERVICE.
8.1. BATTERY MAINTENANCE.
•
Pay attention to any safety instructions stated in EK266*08
manual section 1.2.3 referred to batteries.
•
The useful lifetime of the batteries depends on the ambient
temperature and other factors like the quantity of charging
and discharging cycles and the deep discharges done.
Its design lifetime is between 3 and 5 years if the ambient
temperature is between 10 and 20 ºC. Under request, other
typology and/or design lifetime batteries can be supplied.
•
The UPS from
SLC TWIN PRO2
series only needs a min-
imum maintenance. The used batteries in standard models
are lead acid, sealed, VRLA and maintenance free. The only
requirement is to charge them regularly in order to extend
their lifetime.
Meanwhile, the UPS is connected to mains, started up or
not, it will keep the batteries charged and will guarantee a
protection against overcharge and over discharge.
8.1.1. Notes to replace and install the batteries.
•
In case of replacing any interlink wire, purchase original
parts through the authorised distributors or service centres
in order to avoid over heating or sparks due to the risk that
would entail the use of not enough size.
•
Do not short both battery poles + and -, exists risk of elec-
trocution or fire.
•
Make sure that there is not any voltage before handling the
batteries. The battery circuit is not isolated from the input,
so dangerous voltages between battery and earth can exist.
•
Although the input circuit breaker is turned off, the internal
parts of the UPS are still connected to the batteries, so dan-
gerous voltages are present.
So, before doing any maintenance or reparation, the in-
ternal battery fuse must be removed and/or the connectors
between them and the own UPS too.
As the battery circuit is not isolated from the input, so dan-
gerous voltages between battery and earth or ground (any
metallic part of the cabinet, supports and accessories in-
cluded) can exist.
•
Batteries have dangerous voltages. The maintenance and
battery replacement must be done by qualified personnel
and familiarized with them. No other persons must manipu-
late them.
8.2. UPS TROUBLE SHOOTING GUIDE.

•
Date of the problem.
•
Complete description of the problem, including the informa-
tion supplied by the LCD or leds or alarm status.
•
Power supply condition, type of load and load percentage,
ambient temperature, cooling conditions.

Symptom
Possible cause
Solution
Neither alarms nor indications in the LCD panel and
normal mains voltage.
The input cables are not connected properly.
Check if the input cables are firmly connecte to mains.
The
icon and
warning code blink in the
LCD panel and the acoustic alarm beep every second.
EPO function is activated.
Close the EPO circuit to deactivate it.
The
icon and
BATT FAULT
message blink
in the LCD panel and the acoustic alarm beep every
second.
The internal or external battery are not properly connected.
Check if all the batteries are properly connected.
The
and
icons blink in the LCD panel
and the acoustic alarm beep twice every second.
The UPS is overloaded.
Remove/shutdown the exceeding loads connected at
the UPS output.
The UPS is overloaded. The connected devices to the
UPS are directly supplied from mains through the internal
Bypass.
Remove/shutdown the exceeding loads connected at
the UPS output.
After several overloads, the UPS is blocked on Bypass
mode. The connected devices to the UPS are supplied
directly from mains.
First remove/shutdown the exceeding loads connected
at the UPS output. Then shutdown the UPS and reboot
it .
Code fault 43 is displayed. The
icon lights in the
LCD panel and the acoustic alarm beeps continuously.
The UPS has been overloaded for long time and their
equipment is blocked. The UPS is shutdown automatically.
Remove/shutdown the exceeding loads connected at
the UPS output and reboot it.
Code fault 14 is displayed, the acoustic alarm beeps
continously .
The UPS is automatically shutdown due a short-circuit at
its output.
Check the output wiring and/or connected devices to
its output are short-circuited.
