is handled by higher voltage. A low temperature heightens the output voltage, and hot
condition is handled by lower voltage.
Voltage compensation
Because of some voltage drop in the cables, the actual voltage at the clamps of the battery
can be lower than the charger output voltage. A special circuitry inside the unit will monitor
the true input voltage to the battery and adjust the output voltage of the unit accordingly.
This will maximize the charging efficiency.
Reverse-polarity protection
This unit offers reverse-polarity protection, the RED “REVERSE” LED will illuminate and the
charging process will not start. If this happens, unplug immediately from mains, connect the
red crocodile clip to positive (+) battery post, and black crocodile clip to negative (-) post,
then plug into the mains power and the charging process will start.
Short-circuit protection
Should you accidentally touch the crocodile clips together whilst the mains power is on, the
unit will not perform charging. Unplug from mains, disconnect and start the process again
being careful not to touch the clips together.
Cable connector
The DFC530N has two options for connecting the
unit to the battery. Via the intelligent cable
connector you can select witch connection you
want to use:
• Crocodile clamps for easy and flexible use.
• O-ring connectors for permanent fixation on your battery.
Other features
Anti Spark Protection
Battery and Charger Overheating Protection
Waterproof ABS Housing. Ingress Protection Rating IP65
PLEASE READ CAREFULLY BEFORE USING
Suitable for 6 & 12V Normal Lead Acid, Sealed, Leisure or Gel Batteries between 5-
120Ah.
1. Preparing the battery
Firstly remove the caps from each cell and check that the level of the liquid is sufficient in
each cell. If it is below the recommended level, top up with de-ionized or distilled water.
Note: Under no circumstances should tap water be used.
The cell caps should not be replaced until charging is complete. This allows any gases formed
during charging to escape. It is inevitable that some minor escape of acid will occur during
charging.
For permanently sealed battery, it is not necessary to carry out the above checks.
2. Connection
Connect the positive charging lead (red) to the positive terminal post of the battery (marked P
or +). Connect the negative charging lead (black) to the negative terminal post of the battery
