Electrical connection

The connection scenario in the vehicle must be known before the booster is
integrated into it. A distinction between the following scenarios is required:
Vehicles with Schaudt EBL ..., for which the ground cables to both
F
batteries on the EBL ... are accessible individually. Refer also to Sec-
tion 7.2.
The connection shown in Section 7.2 is the preferred scenario for best
Y
possible distribution of currents.
Vehicles with Schaudt EBL ..., for which the ground connection bet-
F
ween the two batteries is in the vehicle itself, and only a single ground
cable is connected to the EBL ....: This single ground cable is usually
connected at an inaccessible place at the vehicle-side ground connec-
tion of the two batteries. Refer for this to Section 7.2 below.
Vehicles with Schaudt EBL ... with SDTBUS. Refer also to Section
F
7.3.
Vehicles with power supplies from other manufacturers. Here the boo-
F
ster is connected directly to the batteries and a D+ signal. Refer also
to Section 7.4.
DANGER!
Y
The different connection scenarios have a direct bearing on the maximum
currents possible, and so the fusing required. The fusing values specified
may never be exceeded.
DANGER!
Y
Every fuse must be connected in the direct vicinity of the voltage source
(so the respective battery or terminal D+ on the generator).
The temperature sensor also shown in the figures is available an an op-
Y
tion. When this sensor is connected, charging of the leisure area battery
connected is controlled depending on the temperature of the leisure area
battery.
Procedure
The main procedure is essentially the same for all three connection variants:
Fully disconnect both batteries (remove all cables from both terminals).
"
Establish all cable connections as in Figure 6, 7 or 8. Ensure the cables
"
have the cross sections required and that the fuses are installed cor-
rectly. Do not yet insert the fuses into the sockets.
ATTENTION!
Y
Ensure the plug connectors (not included) are readied properly for connec-
ting the batteries to the booster.
Connect the battery temperature sensor (if available) for the two batteries
"
to the negative terminal of the respective battery.
Reconnect the battery terminals of both batteries.
"
Finish off as described in Section 7.7.
"
Set the battery type (see Section 8.4).
