The present Operating Manual (OM) is applicable to automatic battery charger of CH-

105 model (hereinafter referred to as ABC).

The Operating Manual is to be used for study of design, principles of operation and
operating rules of ABC while operating it as per its intended use and during maintenance. The
Operating Manual can also be used for obtaining information on battery chargers for developing
the appropriate sections of operating documentation for the equipment in which ABC can be used
as a component.

1. Purpose

The automatic battery charger CH-105 is to be used on marine and river vessels in dry
service spaces of bridge, superstructures or lower decks and it charges accumulator batteries of
various ship equipment (electronic cartography devices, automatic system, radio communication
devices, etc.), as well as other industrial, transport equipment and communication system
equipment.

4. Principle of operation of battery charger

Battery charger CH-105 allows to charge automatically the accumulator batteries
connected to it (maximum charging current and voltage are set by the user). The battery is
charged by combined method (operation in current stabilization mode in the phase of main
charge with switching to voltage stabilization mode in terminal phase). The example of charging
current and voltage curves of ABC is given on the graphs below (refer to Figure 1):

5. Installation and connection of battery charger

5.1 Installation

ABC is installed in the following sequence:

1. Select and prepare the place for installation of the device so as to ensure free access,

input of cables and termination of their ends. Vertical bulkhead inside the vessel is a convenient
place for installation.

CAUTION! When selecting the place for installation of the device ensure safe
distance to the port-hole so that the water splashes do not penetrate the device when the
port-hole is opened.

ABC shall be installed at a distance at least 1 m away from magnetic compass.

When ABC is installed in the panel or utility room, take into account the
requirements of Para 7.

2. Properly secure the case of battery charger on the vertical bulkhead with the help of bolts or
self-tapping screws. By the effort of hand check for reliability of its fastening. The information on
installation and overall dimensions of ABC are specified in installation diagram of this OM (refer to

Figure 2);

3. Bring the cables of connected devices to ABC. Use the cable of КМПВ (Э) brand or its
substitutes with the appropriate cross-section of cores. When selecting the cable use information on
diameters of cable leads (Table 2) and maximum dimensions of cross-sections of ABC terminals (Table

3).

CAUTION! Before laying and connecting the cables to ABC decide if there is a

requirement to use ABC function on protection of AB from deep discharge and select the
appropriate method of load connection to accumulator battery (refer to Para 5.2.4).
