Handling Of The Cage Tension Spring Clamps; Connection - Truma BC 416 IU Mode D'emploi

The device is designed for operation in an ambient tempera-
ture of up to 35 °C. If the temperature inside the device in-
creases due to a lack of circulating air or due to the fact that
the ambient temperature is too high, the charging current is
automatically reduced gradually.
Handling of the cage tension spring
clamps
Prepare the connection cables. The cable end to be connected
to terminal B+ (small caged spring terminal) must be stripped
over a length of 8 – 9 mm. The cable ends for the battery con-
nections (large cage tension spring clamps) must be stripped
11 – 12 mm. Cable end sleeves are not required.
The spring terminal can be opened up with the aid of a suit-
able slit screwdriver.
Insert the tip of the screwdriver into the upper, square open-
ing, and push on the spring terminal. The spring terminal in
the lower, round opening opens up.
Insert the cable into the spring terminal as far as the insula-
tion (lower, round opening) and remove the screwdriver. The
tension spring clamp closes again and the cable is securely
clamped.
Repeat the procedure for all connections:
B+ Battery sense, + Battery, - Battery.
Make sure that the cable ends sit firmly in the cage tension
spring clamps!

Battery connection
Connect the charger to the battery as shown in the diagram
(fig. 4). Pay attention to the cable cross-sections and ensure
correct polarity.
– Connect the negative charger cable (blue 6 mm²) to the
negative terminal of the charger and the negative terminal
of the battery.
– Connect the positive charger cable (red 6 mm²) to the posi-
tive terminal of the charger for the battery and the positive
terminal of the battery. For cable lengths of over 1 m, this
cable must be equipped with a 30 A fuse near the positive
pole of the battery!
– Connect the measuring cable (red 0.75 mm²) to the B+ input
