Safety precautions
Read the instructions. The manual contains important safety and oper- ating instructions. Always keep this manual nearby the
product.
Read and understand this instruction, the battery instruction provided by your battery manufacturer, and your employer's safety
practice, before using, installing, or servicing the product.
Only qualified personnel should install, use or service this product.
Applies to the European market, EN standard: This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities, or lack of experience and knowledge if they have been given supervision
or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall not be made by children without supervision.
Applies to markets outside Europe, IEC standard: This appliance is not intended for use by persons (including children) with re-
duced physical, sens- ory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that
they do not play with the appliance.
CAUTION
Always connect the battery cables before connecting mains. Disconnect mains before disconnecting battery cables.
Intended use
The battery charger is intended for charging lithium-ion (Li-ion) batteries.
Battery charger and BMS adjustment
The charging process must be controlled by an external Battery Management System (BMS), connected and adjusted to the
battery.
The chargers covered in this manual do not have any internal integrated BMS system, which means that an external BMS system
must be used. The BMS can either communicate with the charger via serial data communication (CAN bus), by analog I/O
functions or both in combination.
When CAN bus is used, the charger and the charging process may be controlled by the BMS system and the battery charger uses
given values from the BMS system to charge the battery. While controlling the charger and charging process via CAN bus, the
BMS system must be able to disconnect the charger and load from the battery by external switches in case of emergency.
The charger can alternatively charge the battery through a pre-set charging algorithm adjusted to the actual battery. Also in this
charging mode, the charging process must be monitored and controlled by an external BMS system. The BMS system must mo-
nitor the charging process and the battery status and must stop the charging al- gorithm generated from the charger if needed.
The BMS unit can communicate with the charger via analog I/O functions but must then also be able to disconnect the charger
from the battery via external switches in case of emergency.
Before start charging
Proper installation of the battery charger and implementation of necessary safety devices and measures, including their mainte-
nance, is the responsibility of the operating company/customer. As a basic rule, a risk and hazard analysis must be prepared in
accordance with local require- ments and best practice.
CAUTION
Incorrect settings of the battery charger may dam- age the battery. Always check settings before start charging.
