11.2 Battery
If the UPS is NOT going to be used for a long period of time, ensure that the batteries are left fully charged. If the
UPS has not been used for more than three months, go through the procedure described in the chapter 7 “First
Start Up” before using it again.
Please keep in mind that the batteries must be recharged at least once a month. Take in mind that batteries are
recharged automatically (if the UPS is ON and working in Normal or in Bypass mode) for after
approximately 10
hours with AC Input line present.
Battery life strongly depends on the ambient temperature. There are also other factors like the number of charge-
discharge cycles, the discharge depth, humidity and altitude.
The recommended environmental specifications for a correct use of batteries are listed in the “Technical
Specifications” section.
Performing Battery Test can provide you with information about Battery condition (see “Battery Test” section for
more information on Battery Test).
Battery replacement must be performed exclusively by qualified technical personnel
authorized by TECNOWARE. TECNOWARE declines any responsibility if this warning is
disregarded.
When replacing batteries, replace with the same type and number.
To remove the batteries, firstly you have to turn off the UPS unit and disconnect the AC
Input Line, then turn off the Battery circuit breaker of the Battery Box unit, disconnect
the Battery cable and disconnect the Input cable for recharging batteries. Then remove
the front panel of the Battery Box unit; behind front panel there is a metal plate: remove
it. So you can access to 5 battery strings (each string has four batteries): disconnect each
string and take out the battery strings. Then disconnect batteries one to each other and
take them off from their housing one by one.
CAUTION - A battery can present a risk of electrical shock and high short circuit current.
The following precautions should be observed when working on batteries:
a) Remove watches, rings or other metal objects;
b) Use tools with insulated handles;
c) Wear rubber gloves and boots;
d) Do not lay tools or metal parts on top of batteries;
e) Disconnect the charging source prior to connecting or disconnecting battery
terminals;
f) Determine if battery is inadvertently grounded. If inadvertently grounded, remove
source from ground.
CAUTION - Do not dispose of batteries in a fire. The batteries may explode.
CAUTION - Do not open or mutilate batteries. Released electrolyte is harmful to the skin
and eyes. It may be toxic.
11.3 Operator Safety
Whenever the UPS is not responding anymore to original characteristics, the UPS must be made non-operative and
every usage not authorised must be avoided. After it will be necessary to refer to qualified technical personnel.
Original safety characteristics might not be if, for example, the UPS has visible damage or irregular operation.
