CHARGEMASTER 12/15-2
Product description and application
The ChargeMaster 12/15-2 is a battery charger for
charging and maintaining the charged condition of
lead batteries and supplying users connected to a
battery in permanent installations. The charger is
provided with two separate DC-outlets, which supply
a total maximum of 15 Amps. The voltage drop over
the DC-wires is automatically compensated.
Installation and instructions for use
1. Due to possible moisture accumulation and
optimal heat discharge, the ChargeMaster
battery charger must be installed in a well-
ventilated room as close as possible to the
batteries. We advise to mount the unit on a flat
metal surface with the connecting cables
downward.
2. See figure 2. Use the cables provided to
connect the charger to the battery set. Connect
the black wire between the charger's negative
output (6) and the minus pole (–) of the battery.
Connect the red wire between the charger's
positive output (7) and the plus pole (+) of the
battery. The plus pole of an optional second
battery set (e.g. a starter battery) should be
connected to the second positive output (8). Be
sure to fix all screws tightly
3. Plug the AC mains cable into the wall socket.
The battery charger will now commence the
charging cycle.
Indications
The charger is equipped with a green LED indicator
(2) that flashes when the unit is charging. The
indicator remains lit continuously to indicate that a
charging cycle has been completed (float). If the
indicator is off while the plug of the AC-cable is
connected to the mains, contact your supplier.
Settings
See figure 1. There are 3 jumpers (3, 4, 5) on the
side of the mains and battery cables for specific
applications of the charger. If necessary, the
jumpers can be removed with small tongs or
tweezers.
In case a battery isolator (diode) is used to
charge several batteries, the output voltage will
be increased (0,6V) to compensate the voltage
drop if jumper (3) is removed
The charger is suitable for charging gel /
AGMbatteries (high float), if jumper (4) is
removed.
The charger only functions as a drop charger
(force float), if jumper (5) is removed.
Via plug (1) various settings can be adjusted in
terms of software to your specific wishes (control
software and interface not included). This plug
can also be used for external warning systems.
Check the Internet site www.mastervolt.com for
applications. Please mind that this plug is not
intended for connecting a battery temperature
sensor.
