INTRODUCTION
Congratulations on purchasing your new CTEK professional switch mode battery charger. This charger is part of a range of
professional battery chargers from CTEK SWEDEN AB. It represents the latest technology in battery charging with charging and
analysis in eight steps with temperature compensation. Read this User Manual and follow the instructions carefully before using
your new charger.
SAFETY
• The charger is designed for lead-acid batteries. 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 corosive. 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 full the national heavy current requirements.
• Check the cabling in the charger before use. Make sure there are no cracks in the cabling or in the protective 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 at 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 battery charger is being used in a safe manner. Store and use the battery charger
out of the reach of children. Make sure that children do not play with the battery charger.
• When using outdoors the charger has to be positioned horizontally with the long side or top side turned up.
CHARGING
Connecting the charger to a battery tted in a vehicle
1. The power cord should be disconnected when connecting or disconnecting the battery leads.
2. Identify the battery terminal that is grounded (connected to the chassis). The negative terminal is normally the grounded post.
3. Charging a negatively grounded battery. Connect the red cable to the positive terminal on the battery and the black cable to good
metal engine ground away from the battery. Ensure you do not connect the black cable to fuel lines or sheet-metal body parts.
4. Charging a positively grounded battery. Connect the black cable to the negative terminal on the battery and the red cable to good
metal engine ground away from the battery. Ensure you do not connect the black cable to fuel lines or sheet-metal body parts.
Connecting the charger to an out of vehicle battery:
1. The power cord should be disconnected when connecting or disconnecting the battery leads.
2. Connect the red cable to the positive terminal on the battery and the black cable to the negative terminal.
If the battery leads have been connected incorrectly, the reverse polarity protection system will ensure that neither the charger nor the
battery are damaged.
Start charging
1. Connect the charger´s AC cord to an AC Power Supply. The charger will indicate POWER, yellow indication lamp (B).
2. The lamp for completely discharged battery (1) will illuminate if the battery’s voltage is less than 12V.
3. Normal charging will be indicated by the following lights: completely discharged battery (1), bulk charging (2), absorption charging
(3) or maintenance charging (4). When the maintenance charging lamp illuminates the battery is fully charged. Charging will start if the
voltage drops. The charger can normally be connected for months. Reconditioning is indicated by the lamp (5) illuminating.
4. If the battery leads have been connected incorrectly, the reverse polarity protection system will ensure that neither the charger nor
the battery are damaged.
5. If nothing happens. If the lamp indicating the setting and the power lamp remain lit but no other lamp illuminates, the connection
to the battery or chassis may be poor or the battery may be faulty. Another cause may be a lack of voltage in the AC Power Supply.
Begin by improving the connection between the battery and charger.
6. Charging can be stopped at any time by disconnecting the charger’s AC cord. Always disconnect the AC cord before disconnecting
the battery leads. When you stop charging a battery installed in a vehicle you should always disconnect the battery lead from the
chassis before disconnecting the other battery lead.
