Handling Of The Cage Tension Spring Clamps; Connection - Truma BC 616 IU Mode D'emploi

Ensure that the ventilation slits remain free! There
should be a minimum clearance of 100 mm all round!
Inadequate ventilation can cause the device to overheat!
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 this procedure for all connections:
B+Battery sense, + Battery I, + Battery II,
- Battery I, - Battery II.

Ensure that the cable ends are securely clamped into the cage
tension spring clamps!

Connection

Disconnect the power cables from the battery and from
the mains before connecting or disconnecting any ca-
bles! Only use the specified cross-sections and fuses with the
correct rated current!
Positive charger cable red
Cable cross section 6 mm²
Negative charger cable blue
Cable cross section 6 mm²
B+ measuring line red
Cable cross section 0.75 mm²
Connecting the batteries
Connect the charger to the supply battery (battery II) as shown
in the diagram (fig. 3). Check that the correct cable cross-sec-
tions are used and that the terminals are connected correctly!
– Connect the negative charger cable for the battery II (blue
6 mm²) to the negative terminal of the charger and the
negative terminal of the battery II.
– Connect the positive charger cable for the battery II (red
6 mm²) to the positive terminal of the battery II on the
charger and the positive terminal for the battery II. For cable
lengths of over 1 m, this cable must be equipped with a
30 A fuse near the positive pole of the battery II!
– Connect the measuring cable (red 0.75 mm²) to the B+ in-
put on the device and the positive terminal of the battery II.
For cable lengths of over 1 m, this cable must be equipped
with a 2 A fuse near the positive pole of the battery II!
