damage the battery and generate explosive
gases from the battery during charging.
Always check settings before start charging.
•Do not charge non-rechargeable batteries,
damaged batteries or battery types not
intended for the charger.
•Do not disconnect the battery when the charg-
ing process is in progress. Sparks may occur
and cause hydrogen explosion when charging
lead-acid batteries. Arc flash may occur and
damage the connector pins. Always stop the
charging process before the battery is
disconnected.
No open flame. Fire, open ignition
source and smoking are prohibited
near battery.
•Explosive gases. Prevent flames and sparks.

Description
Sharp 20 are regulated battery chargers. Sharp
exists in different versions either for charging
flooded or valve regulated lead-acid batteries.
They can also be equipped with a charging curve
for Ni-Cad batteries or similar.
The battery charger is supplied with a pre-set
charging curve adapted to the type of battery
specified during ordering. Information about the
set charging curve can be read on the outside of
the battery charger.
The built-in microprocessor controls current and
voltage during the charging process. The status
of the charging process is displayed with an LED
on the front panel of the charger. The charging
time and temperature of the charger are moni-
tored throughout the charging process, charging
is limited in the event of defect cells or insufficient
cooling etc. During the charging process, the
charger continuously gathers data and performs
calculations in order to fully recharge the battery
with respect to amount of discharge, temperature,
age etc. The battery charger is cooled by means
of a temperature-regulated fan.
Receiving
On receipt, visually inspect the product for any
physical damage. If necessary, contact the
transport company.
Check the delivered parts against the delivery
note. Contact your supplier if something is
missing, see Contact information.
Installation
NOTE
Installation may only be performed by qualified
service partner.
The battery charger must be
installed in a dry and clean
environment.
1. Locate the battery charger so that there is free
circulation of air through the battery charger’s
ventilating openings.
2. If several battery charges are to be mounted
next to each other, they may not be located so
that cooling air from one battery charger blows
into the air intake of another battery charger.
3. Mount the battery charger as per figure Sharp
20 P4 - fig. 1a / Sharp 20 P4 - fig. 1b / Sharp
20 P6 - fig. 2. Dimensions for free space
around the battery charger shouldn´t fall below
those specified dimensions.
4. Install the battery charger so that the gasses
from the battery being charged do not get
sucked into the charger by its fan.
5. The battery charger can be used horizontally
on a table, suspended on a wall with an
accompanying bracket.
6. For installation on a wall or for internal
mounting, the battery charger should be
placed horizontally to prevent penetration of
moisture and dirt.
7. The battery charger is produced in different
mains voltage variations. Check that the
power supply at the site of the installation
complies with the rate voltage according to the
information on the battery charger’s rating
plate.
ENGLISH
5
8. The recommended mains fuse is specified on
the battery charger’s rating plate.
9. The battery charger is connected to the mains
voltage via a cable with a plug to an earthed
wall socket.
10.Connect the battery charger as per figure
Sharp 20 P4/P6 - fig. 3. The red cable is
connected to the battery’s positive pole and
the black or blue cable is connected to the
battery’s negative pole. Carefully check the
marking on the battery.
11. Upon request, the battery can be permanently
connected or detachable.

WARNING
In the case of danger, disconnect the mains
voltage by pulling out the plug from the wall
socket.
Connecting a battery
1. Check that the battery charger is turned off.
The switch on the panel should be in the 0-
position (applies to Sharp 20 P4). Battery
charger Sharp 20 P6 can be continuously to
the mains.
2. Check the wiring and adapter to ensure that
there is no visible damage.
3. Connect the battery to the battery charger.
4. Start the battery charger by setting the switch
on the panel to the 1-position (applies to
Sharp 20 P4). Battery charger Sharp 20 P6
automatically starts charging when the battery
is connected. Yellow LED lights. Charging time
will vary depending on the type of battery and
the degree of discharge.
5. Green LED is displayed when the battery is
fully charged. The battery charger change to
maintenance charging.
NOTE
The green LED will not light immediately if a fully
charged battery is connected. This time can vary
between 0 and 2 hours.
Disconnecting a battery
WARNING
The battery charger should be turned off when dis-
connecting the battery. If the battery is disconnect-
ed during an ongoing charge, the contacts in the
charging connector will be damaged and spark
formation can occur causing a hydrogen gas
explosion.
1. Turn off the battery charger. Set the switch on
the panel to the 0-position (applies to Sharp
20 P4). Press the Reset button (applies to
Sharp 20 P6).
2. Disconnect the battery from the battery charg-
er (applies to Sharp 20 P4). Disconnect the
battery immediately after the reset button is
pressed. Charging is resumed after 10
seconds if the battery is still connected
(applies to Sharp 20 P6).
Maintenance and
troubleshooting
The checks below are recommended to be car-
ried out during troubleshooting and maintenance.
WARNING
High voltage!
Only qualified personnel should install, use,
maintain and service this product.
Disconnect the battery and power supply before
maintenance, servicing or dismantling.
ENGLISH

WARNING
High voltage!
If there is evidence of damage to the battery
charger, cables or connectors, switch off the
mains power. Do not touch damaged parts.
Do not touch uninsulated battery terminals,
connectors, or other live electrical parts.
Contact service personnel.
Safety shut-off
Charging is terminated if:
•The recharged number of ampere hours
exceeds the preset value.
•The charging time for any of the charging
phases exceeds the preset value.
•Voltage and current exceed the maximum set
value.
•The battery is disconnected without the
battery charger being stopped.
Charging is temporarily stopped or reduced when:
•The battery charger temperature exceeds
charger limits.
Checking error messages
If the battery charger’s built-in self-testing function
detects a fault, this is indicated via the status
LED’s on the front panel. Red flashing LED
indicates a charging fault. Red fixed light
indicates a fault in the charger.
Please make a note of any faults and send for
authorised service personnel.
Checks
1. Check the cables and connectors for
damages.
2. Check that the battery is free from defects, in
good condition and is the correct type for the
battery charger.
3. Check that the battery is properly connected
and that the battery fuse, if any, is not broken.
4. Check that the mains voltage is right and that
there are no blown fuses.
Recycling
The battery charger is recycled as metal and
electronics scrap. Local regulations apply and
must be followed.
