Connection; Disconnecting; Select Charging Mode - PowerTech MB3912 Instruction Manual

CONNECTION:

• Before starting the charging or discharging procedure on a permanently
installed battery in a vehicle, first disconnect the minus pole connecting
cable (black) of the vehicle from the minus pole of the battery. The
minus pole of the battery is usually connected to the car body.
• Then disconnect the plus pole connecting cable (red) of the vehicle
from the plus pole of the battery.
• First attach the "+" quick-release clamp (red) of the battery charger to
the "+" terminal of the battery.
• Attach the "–" quick-release clamp (black) of the battery charger to the
"–" terminal of the battery.
• Connect the mains lead of the battery charger to an electrical power
outlet socket.

DISCONNECTING:

• Disconnect the appliance from the power supply.
• Detach the "–" quick-release clamp (black) from the "–" terminal of
the battery.
• Detach the "+" quick-release clamp (red) from the "+" terminal of
the battery.
• Reconnect the plus pole connecting cable of the vehicle to the plus
pole of the battery.
• Reconnect the minus pole connecting cable of the vehicle to the
minus pole of the battery.

SELECT CHARGING MODE:

You can select different charging modes for charging different batteries at
different ambient temperatures. In comparison with conventional battery
charging stations, this appliance has a special function for reusing an empty
battery or rechargeable battery. Safe charging is ensured by means of a
protection against incorrect connection and short circuiting. Due to the
installed electronics, the charging station does not begin operation directly
after connecting the battery, but only starts after a charging mode has been
selected.
This avoids sparking, which often occurs when connecting. The battery
charger is controlled by an internal MCU (Micro-Computer Unit).
NOTE: It is important to understand the differences and purpose of each
charge mode. Do not operate the charger until you confirm the appropriate
charge mode for your battery.
