-
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water for at least 10 minutes and get medical attention immediately.
-
NEVER smoke or allow a spark or flame in the vicinity of the battery or engine.
-
Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or other electrical parts which may cause an explosion.
-
Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
-
ONLY POWER LEAD/ACID, AGM, EFB, GEL, and LITHIUM TYPE BATTERIES. OTHER TYPES OF BATTERIES MAY BURST CAUSING PERSONAL INJURY AND DAMAGE. It is not intended to supply power to a low-voltage electrical system other than in a starter-motor application. Do not use the power supply for charging dry-cell batteries that are commonly used with home appliances.
These batteries may burst and cause injury to persons and damage to property. -
NEVER power a frozen battery.
-
PREPARING TO CHARGE

GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS
The power supply must be grounded to reduce risk of electric shock. The power supply is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. DANGER – Never alter AC cord or plug provided – if it will not fit the power outlet, have proper outlet installed by a qualified electrician. Improper connection can result in a risk of an electric shock. -
This power supply is intended for use with a nominal 120-volt circuit, which has a grounding plug that looks like the plug illustrated in Figure A. Do not attempt to use an adapter or extension cord.
INSTALLATION
Connect the power supply in accordance with the wiring diagram. Find a
suitable place to install the power supply in a distance from the battery that
does not exceed the length of the enclosed 12V charging cable. If the cable is
extended or cut, the power supply will provide wrong voltage. If the 12V cable
is extended, a cable with a larger cross-section must be used. Connection to
the battery must always be made with the enclosed fuse. Use at least two or
more holes on the fastening bracket to install the power supply or use the
supplied cable ties. Make sure the power supply is not placed too close to hot
parts such as an exhaust manifold, turbo and so on. It must also be positioned
well clear of moving parts such as pulleys, cooling fans and steering rods.
To achieve voltage on both engine- and interior heater output the control
inlet signal (marked with a clock) on the power supply must be supplied with a
+12V signal. This is normally supplied via the DEFA control units yellow
cable. If a control unit is not mounted, this signal can be achieved using the
red cap that comes with the power supply. The relay will only be activated and
load voltage when both +12V control signal and 120V is connected to the power
supply.
- It is most important that the power supply is installed in accordance with the installation guide and that DEFA´s original connection equipment is used, see specific installation guide.
- Some vehicles have a battery monitoring system. Connect ground according to the vehicle manufacturer’s recommendation.
USE
The power supply has the following characteristics:
- 4A charging output.
- Power distribution and integrated relay for switching engine and interior heater on and off.
The power supply operates independently of the start timer for the car heating system. The power supply can also be used to advantage in the summer. Avoid powering batteries in an enclosed area, as there is a potential danger of explosion. The ambient temperature of the battery should not exceed +40ºC during powering. The power supply contains high voltage. In order to prevent potentially dangerous situations involving faulty batteries, the power supply requires a back voltage of approximately 2V to start operating. It can therefore not be used as a 12V battery eliminator.
