User Manual
SG Series 225 & 300 UL S2
9.1.4 Battery
We recommend a periodic
Manual Battery Test
, especially if the
Automatic Battery Test
is disabled, in
order to verify if the
Battery
can provide the expected backup time in case of
Utility Failure
.
We recommend this test be performed at least every
3 months
, especially if the
Battery
is not
sufficiently discharged during normal operation.
The discharge time you use should be at least half of the
Battery
runtime.
For
Automatic Battery Test
setting, a special code is required to enter user set-up parameters.
The start up technician has access to this code and can program this feature during start up.
Please consider that, if you did a full
Battery Test
to verify the full runtime of the
Battery
, the charger
needs at least
8 hours
to recharge the
Battery
up to 90% of its capacity.
9.1.5 Long shut-down periods of the UPS-system
To guarantee that the
Battery
is fully charged, the UPS system should be in operation for at least
12
hours every 3 months
.
If not the
Battery
may be permanently damaged.
9.1.6 UPS room conditions and temperature
The UPS room and the
Battery Room
have to be maintained clean and free from dust.
A high temperature of the UPS room and of the
Battery Room
affect the lifetime of several components
inside the equipment.
The
Battery
is very sensitive to room temperatures above
77°F
(25°C).
9.1.7 Long shut-down periods of the UPS-system
a) Cleaning, a visual inspection and a mechanical inspection of the UPS modules.
b) Replacement of defective parts or the preventive replacement of parts with a defined lifetime
c) “Updating” of the equipment (technical improvements subsequent to the delivery).
d) Check the calibration of
DC voltage
and
Inverter Output Voltage
and
Frequency
.
e) Check of the settings of the electronic regulation, the control and the alarm circuits of the
Rectifier(s)
and
Inverter(s)
.
f) Functional checks on
Thyristors
,
Diodes
,
Transformers
,
Filter Components
, e.g. to ensure that they
are operating within the specified design parameters.
g) Overall performance test including a
Utility Failure
simulation with and without the
Load
.
h) Monitoring
Battery
operation in discharge and recharge mode including any boost charge duties.
