SAFETY
The charger is designed for lead-acid batteries from 8–100Ah. However, the charger can
maintain batteries up to 250Ah. Do not use the charger for any other purpose
Use safety glasses and turn your head away when connecting or disconnecting a battery.
Battery acid is corrosive. Rinse immediately with water if acid comes into contact with skin or
eyes. Seek medical advice.
Make sure that the cable is not being pinched or in contact with warm surfaces or sharp
edges.
While charging, a battery can emit explosive gases, so it is important to avoid sparks in the
immediate area.
Always provide for proper ventilation during charging.
Avoid covering the charger.
Make sure that the electrical cable does not come into contact with water.
Never charge a frozen battery.
Never charge a damaged battery.
Do not place the charger on the battery while charging.
The electrical connection must fulfil the national heavy current requirements.
Check the cabling before use. Make sure there are no cracks in the cabling or in the protec-
tive covering. A charger with damaged cables may not be used.
Always check that the charger has gone over to maintenance charging mode before leaving
the charger unattended and connected for long periods. If the charger had not gone over
to maintenance charging within 3 days, this is an indication of a problem. In this case the
charger must be disconnected manually.
All batteries fail sooner or later. A battery that fails during charging is normally taken care of
by the chargers advanced control, but certain uncommon errors in the battery can still arise.
Don’t leave the battery charger unattended for a longer period of time.
Only mount the charger on a flat surface.
This equipment may not be used by children or by those who can not read and understand
the manual if they are not supervised by a responsible person who can guarantee that the

The following recommendations should, however, only be seen as guidelines. When in doubt,
always consult the battery manufacturer for further instructions.
Settings are made by pressing the “MODE-button” and stepping forward by pressing the button
one step at a time, releasing the button when the required mode is reached. After approx. 2
