Before each use check the conditions of the rectifier, including the conditions of the power cord and the charging conductors.
Should any damage be detected, stop using the rectifier. Damaged cables and conductors must be replaced with new ones in a
professional workshop.
Before any maintenance of the rectifier is executed, make sure the plug of the power cord has been disconnected from power
supply socket.
The rectifier must be stored away from unauthorised persons, particularly children. Also during work make sure the rectifier is
placed outside the reach of unauthorised persons, particularly children.
Before connecting the terminals of the rectifier, make sure the terminals of the accumulator are clean and free from corrosion.
Provide the best possible electric contact between the terminal of the accumulator and the terminal of the rectifier.
Do not ever charge a frozen accumulator. Before you commence charging, move the accumulator to a place in which the electro-
lyte may totally defrost. Do not heat accumulators in order to accelerate defrosting.
Preclude any leakage from accumulators. Any leakage from the accumulator on the rectifier may cause a short-circuit and thus an
electric shock, which may be dangerous for health and life.
OPERATION OF THE RECTIFIER
Preparation of the accumulator for charging
Get acquainted with the charging instructions provided along with the accumulator and observe them. In the case of the so called
„wet" acid-lead accumulators" it is necessary to check the level of electrolyte and, if required, replenish it with distilled water to
the level indicated in the documentation of the accumulator. While replenishing the level of electrolyte, observe strictly the recom-
mendations indicated in the documentation of the accumulator.
Using the switch marked as „12V/24V", select the adequate nominal voltage of the accumulator to be charged.
Using the switch marked with as „MIN/BOOST", select the charging rate. The „MIN" setting provides a lower current sent to the ter-
minals of the rectifier, and it is recommended for deeply discharged accumulators, for example those which have been stored for
a long time without charging or those whose voltage on the terminals is lower than 9 V for 12 V accumulators. This setting should
be used as a regular setting of the rectifier during work. The „BOOST" setting provides a high charging current, and it should be
used solely for the purpose of charging up of an accumulator, which is not deeply discharged. Make sure a higher charging current
does not cause any damage to the accumulator. In case the temperature of the accumulator being charged rises excessively, the
switch should be placed at „MIN" or the charging should be stopped.
The cable with a terminal marked as „+" must be fixed with a rectifier clamp handwheel. Make sure the chosen terminal corre-
sponds to the nominal voltage of the battery.
Using the switch marked as „1/2", select the adequate charging current in the „MIN" mode, in accordance with the table below.

In case the switch is at the „BOOST" position, the position of the „1/ 2" switch does not matter. The „BOOST" function permits to
obtain a higher current than the nominal current of the rectifier, but for a short period. In case the current is applied in the „BOOST"
mode for too long, the temperature limit fuse of the rectifier will be activated and it will cut off the charging current until the rectifier
has cooled down. Once the rectifier has cooled down, the charging process will be automatically reinitiated.
Connect the terminals of the rectifier to the terminals of the accumulator, make sure the terminal of the rectifier marked with a „+"
is connected to the terminal of the accumulator marked with a „+" and the terminal of the rectifier marked with a „-" is connected
to the terminal of the accumulator marked with a „-".
Connect the plug of the power cord to the power supply socket.
During the process of charging, the value of the current sent to the terminals of the accumulator may be observed on the indicator
in the housing of the rectifier.
Once the process of charging has concluded, disconnect the plug of the power cord from the power supply socket, and then
disconnect the accumulator from the rectifier.
MAINTENANCE OF THE DEVICE
The device does not require any special maintenance. A dirty housing should be cleaned with a soft cloth or with a compressed
air jet, whose pressure must not exceed 0.3 MPa.
Check the conditions of the terminals of the conductors before and after each use. Remove any signs of corrosion, which might
disturb the flow of the electric current. Avoid contamination of the terminals with the electrolyte from the accumulator, since it would
accelerate the process of corrosion.
The device should be stored in a dry place, away from unauthorised persons, particularly children. Make sure the cables and
conductors are not damaged during storage.
