• Use safety glasses and turn your head away when connecting or disconnecting a battery.

• Battery acid is corosive. Rinse immediately with water if acid comes into contact with skin or eyes. Seek medi-

cal 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.

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.

BATTERY TYPES AND SETTINGS

MULTI XS 3600 can easily be configured to charge many different types of 12V lead-acid batteries; wet batteries,

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.

Mode 14.4V/0.8A

This mode is normally used for <14Ah batteries.

Mode 14.4V/3.6A

Normal setting for wet batteries, MF and for most GEL batteries.

Mode 14.7V/3.6A

This setting is recommended for batteries at temperatures
below 5°C. It is also recommended for many AGM batteries.
This setting is not recommended for maintenance charging
when the temperature at times exceeds +5°C. In this case, the

14.4V/3.6A mode is recommended.

CHARGING

Charging batteries mounted in a vehicle:

1. The power cord should be disconnected before connecting or disconnecting the battery leads.

2. Identify the pole that is grounded (attached to the chassis). Ground is normally connected to the negative
terminal.

3. Charging a negatively grounded battery. Connect the red wire to the positive pole of the battery and the black
cable to the vehicle’s chassis. Be careful not to connect the black cable in the vicinity of a fuel pipe or the bat­tery.

4. Charging a positively grounded battery. Connect the black wire to the negative pole of the battery and the red
cable to the vehicle's chassis. Be careful not to connect the red cable in the vicinity of a fuel pipe or the battery.

Charging of a battery not connected to a vehicle:

1. The power cord should be disconnected before connecting or disconnecting the battery leads.

2. Connect the red wire to the positive pole of the battery and the black cable to the negative pole.
