(standby-

hould be applied.
b.) Buffer operation
With
buffer
operation
the
battery
charger
is
not
able
to
supply
the
maximum
load
current
at
all
times.
The
load
current
intermittently
exceeds
the
nominal
current
of
the
battery
charger.
During
this
period
the
battery
supplies
power.
This results in the battery not fully charged at all
times.
Therefore,
depending
on
the
load
the
charge voltage must be set
a
c
c. to table 4
. This
has
to
be
carried
out
in
accordance
with
the
manufacturers instructions.
c.) Switch-mode operation
When charging, the battery is separated from the
load. The charge voltage of the battery must be
set
acc.
to
table
3
(
m
ax.
values).
The
charging
process must be monitored. If the charge current
reduces
to
less
than
1.5

,
the
mode switches to float charge acc. to item 2.3 or
it switches after reaching the voltage value acc.
to table 3.

d.)
Battery operation (charge-/discharge
operation)
The
load
is
only
supplied
by
the
battery.
The
charging
process
depends
on
the
application
and must be carried out in accordance with the
recommendations of the battery-manufacturer.
2.3
Maintaining the full charge (float charge)
Devices complying with the stipulations under
DIN 41773 must be used. They are to be set so
that the average cell voltage is
a
c
c
. to
table 2
.
2.4
Equalizing charge
Because
it
is
possible
to
exceed
the
permitted
load
voltages,
appropriate
measures
must
be
taken,
e.g.
switch
off
the
load.
Equalizing
char-
ges
are
required
after
deep
discharges
and/or
inadequate
charges.
They
can
be
carried
out
with
2.40
Vpc
(A
500:
2.45
Vpc)
for
up
to
48
hours and with unlimited current.
The cells / bloc temperature must never exceed
45° C. If it does, stop charging or revert to float
charge to allow the temperature to drop.
2.5
Alternating currents
When recharging up to 2.40 Vpc under operation
modes 2.2 the actual value of the alternating cur-
rent is occasionally permitted to reach
10 A (RMS) / 100 Ah C
10
. In a fully charged state
during float charge or standby parallel operation
the
actual
value
of
the
alternating
current
must
not exceed 5 A (RMS) / 100 Ah C
10
.
2.6
Charging currents
The
charging
currents
are
not
limited
during
standby
parallel
operation
or
buffer
operation
without
recharging
stage.
The
charging
current
should range between the values given in
t
a
b
le 5
(guide values).
In
cycling
operation,
the
maximum
current
values
as
shown in t
a
ble
5
m
ust
not
be
excee-
ded.
2.7
T
e mperature
The recommended operation temperature range
for
lead
acid
batteries
is
10°
C
to
30°
C
(best:
nominal temperature ± 5K). Higher temperatures
will seriously reduce service life. Lower tempera-
tures reduce the available capacity.
The absolute maximum temperature is 55° C and
should not exceed 45° C in service.
All technical data refer to a nominal temperature
of 20° C and 25° C respectively.
2.8
T
e mperature related charge voltage
The
temperature
related
adjustment
has
to
be
carried out
a
cc. to the following figures 1 to 5
.
An adjustment of the charge voltage must not be
applied within
a specified temperature
range as
shown in
