that can cause personal injury.
•Disconnect the battery and power supply before maintenance, servicing or dismantling.
•Check that the power supply at the site of the installation complies with the rated voltage specified on the
battery charger’s data label.
•The battery charger may only be connected to a power outlet with protective earth.
•Do not operate the charger if there is any evidence of damage.
•If the supply cord or plug is damaged:
•The manufacturer, its service agent or similarly qualified persons must carry out any replacement of the
cord / plug in order to avoid a hazard.
•Appliances with specially prepared cords must be replaced by a special cord or assembly available from the
manufacturer or its service agent.
•Other appliances that have a supply cord that cannot be replaced, should be scrapped.
•If a stationary appliance is not fitted with a supply cord and a plug, or with other means for disconnection from
the supply mains, disconnection must be incorporated in the fixed wiring in accordance with the national wiring
rules.
WARNING, risk of electric shock. High output voltage. Do not touch uninsulated battery terminals, con-
nectors or other live electrical parts.
When installing or performing work on battery, charger and battery terminals – do not risk short circuits. A short
circuit may cause personal injury and permanently damage the battery. For all work on battery chargers, batteries
and BMS, suitable insulated tools must be used.

Description
Sharp 10 is a regulated battery charger, available in different designs, for charging either flooded or valve-regulated
lead-acid batteries.
The battery charger is supplied with a pre-set charging curve adapted for the battery type specified on
order. A set charging curve can be read off the battery charger's data label.
The regulated charger controls current and voltage throughout the charging process. Charging progress is
indicated by LEDs on the battery charger panel. Charging time and the temperature of the battery charger are
monitored and charging is limited in the event of faults with cells or inadequate cooling. Throughout the charging
process, the battery charger collects data and performs calculations in order to ensure the battery is fully charged
based on the level of discharge, temperature, age, etc.
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 is manufactured in different mains voltage versions. Check that the mains voltage in the
installation location matches the battery charger’s rated voltage as per the charger’s data label.
•The recommended mains fuse is specified on the battery charger’s data label.
•The battery charger should be installed on a metal base plate to ensure maximum cooling.
•The battery can have a permanent connection, or it can be connected as required.
•The battery charger is connected to the mains power using a cable with a plug inserted into an earthed wall
socket.
•Battery chargers bearing the symbol must be connected to an unearthed wall socket.
1. Install the battery charger as shown in figures P2 - fig. 1a / P3 - fig. 1b / P1 - fig. 1c.
2. Check the polarity of the battery connector and cable before connecting the battery. The charger is normally
delivered with a battery cable with the following polarity:
•Positive (+) = Red
•Negative (−) = Blue or Black
3. Connect the battery cables to the battery.
