Safety instructions

Target group:
For skilled electricians and trained personnel
in accordance with national legislation,
including the relevant standards and,
where applicable, in acc. with IEC 60079-17
on electrical apparatus for explosive
atmospheres.
The battery must not be operated in zone 0
or zone 20 hazardous areas!
2 General information about the
charging technology
The microcomputer controlled charging system
measures the charging and discharging current
and transmits it to a capacity meter. Five green
light emitting diodes indicate in 20%-steps
the actual charge state of the battery
Overcharging is prevented by means of this
charging control dependent on the capacity.
Only the energy drawn is recharged. The so-
called memory effect is thus also prevented.
For electrochemical reasons charging and
the capacity are influenced at temperatures
below -5°C and above +35°C. At temperatures
below -5°C and above +35°C charging will take
a longer time and full charging is not guaran-
teed.
3 Charging
3.1 Initial Charging
Battery charging starts when the power is
switched on. On the connection of a new
battery the indication of the charge state may
be delayed by a few minutes. The first green
LED might take a few minutes to start flashing.
After a charging period of 14 hours the battery
will have reached approx. 90% of its rated
capacity. As the capacity of the battery is over
specified, this 90% will be sufficient to provide
a rated discharge for both a 90 minute and
180 minute setting.
Initial charging at 0°C ambient temperature
might take double the time than at temperatu-
res of >10°C
After first mains connection an uninterrupted
charging time of 20 hours is recommended to
avoid early ageing due to power-on power-off
situatuions. The battery set is only partially
charged when supplied.
EATON's Crouse-Hinds Business
Multiple switching (on - off) of the mains
circuit should be avoided before a first initial
charge (recommended 20h, minimum 14h)
is achieved. Such interruptions can signifi-
cantly reduce the lifetime of the battery.
Recomendation: New batteries will reach the
full utilisable capacity after approx. 3 charging /
discharging cycles.
3.2 Charging during operation
The charging current is engineered in such a
way that a discharged battery will have within
14h approx. 90% and within 20h approx. 100%
of it´s capacity.
In emergency operation the battery voltage
is monitored via a deep discharge protection
which prevents a deep discharge of the cells.
The microprocessor controlls and re-charges
any reduction of capacity due to self-discharge
in normal operation.
It is recommended to have one or two fully
discharges per year. This increases the usable
life time of the battery.
Should this not be possible due to logistic and
safety reasons at least a partial discharge of a
minimum of 40 minutes or 2 hours depending
on the setting, is recommended.
3.3 Charging after storage
After a long storage of the batteries a full
uninterupted charge for 20 h should be applied
followed by a full discharge down to deep
discharge protection (emergency lamp off).
If the capacity indication does not show 5 green
LED´s fully lit after 14 h, the above process
should be repeated. For a storage period
> 6 months it is recommended to have
3 charging/discharging cycles.
