TECHNICAL INFORMATION
(*) Opportunity Prole Options
Operation: In opportunity charging mode, the user
can charge the battery during breaks, lunch, or
any available time during the work schedule. The
opportunity charge prole allows the battery to be
safely charged while it is kept in a partial state of
charge between 20% and 100% of C5 throughout the
work week. Sufcient time should be scheduled after
the weekly equalize charge to allow battery cooling
and to perform periodical electrolyte level checks.
Daily Charge:
This option can be set to add additional daily charging
time, if the work schedule allows. It should be
considered only when the daily work demand requires
additional capacity.
Equalization Charging
Equalization charging for lead-acid batteries,
performed after normal charging, balances the
electrolyte densities in the battery’s cells.
NOTE: The factory default is Daily Charge DISABLE,
6-8 hours Equalize, Sunday at 00 hour for ooded,
2-hour week/maintenance charge for NexSys
®
charging proles.
Block-Out Time
This function inhibits the charger from charging
the battery during the block-out time window. If a
charge cycle has started before the block-out window
it is stopped during the block-out window and will
automatically restart the charge cycle at the end of the
block-out window.
Refresh Charging
Refresh or maintenance charging enables the charger
to maintain the battery at maximum state of charge as
long as it is attached to the charger.

Safety Precautions
1.
WARNING
The shipping pallet must be
removed for proper and safe operations.
2. This manual contains important safety and
operating instructions. Before using the battery
charger, read all instructions, cautions and
warnings on the battery charger, the battery and
the product using the battery.
3. Read and understand all setup and operating
instructions before using the battery charger, to
prevent damage to the battery and to the charger.
4. Do not touch non-insulated parts of the output
connector or the battery terminals to prevent
electrical shock. Never open the equipment: High
voltage could be still present, even after turning
off the charger. Any adjustment, maintenance or
repairs to the equipment while it is open must
only be carried out by an appropriately skilled
person who is aware of the risks involved.
5. During charge, lead-acid batteries produce
hydrogen gas, which can be dangerous if
ignited. Never smoke, use an open ame or
create sparks in the vicinity of the battery. Take
all necessary precautions when the equipment
will be used in areas where there is the possible
risk of an accident occurring. Ensure appropriate
ventilation according to standard EN 62485-3 or
local regulations to allow any gases released to
escape. Never disconnect the battery while it is
being charged.
6. Unless charger is equipped with LMEB (Late
Make/Early Break) feature, do not connect or
disconnect the battery plug while the charger is
on. Doing so will cause arcing and burning of the
connector, resulting in charger damage or battery
explosion.
