The
For best preventative maintenance, keep the area around the unit
clean and free of dust. If the environment is very dusty, clean the
exterior of the system with a vacuum cleaner.
8.2. BATTERY MAINTENANCE.
Pay attention to all of the safety instructions regarding the
batteries, indicated in the EK266*08 manual, section 1.2.3.
The service life of the batteries depends significantly on the
ambient temperature and other factors such as the number of
charges and discharges, as well as the depth of these.
Their design lifetime is between 3 and 5 years if the ambient
temperature to which they are subjected is between 10 and 20ºC.
On request, batteries of a different type and/or design lifetime can
be supplied.
The batteries used in standard models are sealed lead-acid, valve-
regulated and maintenance-free. The only requirement is to charge
the batteries regularly to extend their life expectancy.
As long as the UPS is connected to the supply network, whether
or not it is in operation, it will keep the batteries charged and will
also provide protection against overcharging and deep discharge.

series requires minimal maintenance.
8.2.1. Replacing the batteries.
If a connection cable must be replaced, purchase original materials
through our T.S.S. or authorised distributors. Using inappropriate
cables can lead to overheating in connections that carry a fire risk.
There are permanent dangerous voltages inside the unit,
even without mains supply present, due to its connection
with the batteries, and especially in UPS units where the electronics
and batteries share the same enclosure.
Also take into consideration that the battery circuit is not isolated
from the input voltage, so there is a risk of dangerous discharge
voltages between the battery terminals and the earth terminal,
which in turn is connected to the earth (any metal part of the unit).
DO NOT DISCONNECT
Battery mode.
Repair and/or maintenance work is reserved for the T.S.S.,
except for battery replacement, which can be carried out
by qualified personnel who are familiar with them. No other
person should handle them.
