CTEK MXS 3600 - Manual (Page 4)

Connecting the provided cables with eyelet terminals:
Make sure that the cable is not being pinched or in contact with warm surfaces or sharp edges. When the cable
is mounted on the battery, it should not be connected to the charger. Connect the eyelet terminals to the battery's
poles - the red cable to the positive pole and the black cable to the negative pole. After this, the quick contact can
be connected.
Reverse Polarity Protection
If the battery cables are connected incorrectly, the reverse polarity protection will make sure that the charger and
the battery are not damaged. In this case, the red warning lamp (0) will be lit.
Start charging
1. Set the proper charging mode for the battery by pushing the Mode button until the correct setting is lit. Choosing
settings for your battery is described under ”BATTERY TYPES AND SETTINGS”.
2. When you are sure the battery leads are correctly placed, connect the power cord to the power outlet to begin
charging. If the battery leads are wrongly connected, the pole-changing switch will ensure the battery and char-
ger are not damaged. The fault indicator will light. In which case start from the beginning again.
3. The charging lamp will now indicate charging or the maintenance lamp will indicate that the battery is
fully charged. If the voltage drops the charger sends a pulse to the battery. The length of the pulse depends on
how much the voltage has dropped. The charger can be connected for months.
4. If nothing happens: If the voltage indicator is lit but no other lamp is lit there could be a bad connection to the
battery or chassis or the battery could be faulty. Check the wall power outlet. If you experience problems: start
with the sensitive connection between the battery clamps and the charger.
5. Charging can be stopped at any time by disconnecting the supply cord or by setting the charger on Standby.
Always remove the power cord from the power outlet before disconnecting the battery leads from a battery in a
vehicle. When you stop charging a battery in a vehicle, remove the cable from the chassis before removing the
other cable.
6. If the charger lamp and the maintenance-charger lamp are flashing alternately, the reason for this is due to:
• An interruption during charging, due to a loose connection or because the battery has ceased to work.
• The battery has become sulphated. If the lamps flash for more than 30 minutes, this indicates that the battery is
dead and needs to be replaced.
• If there is an interval of more than 10 seconds between the flashes, this indicates that the battery has a high
self-discharge rate and may need to be replaced.
