Setup, Installation and Fuses
2.1
Position of Plug Connections
The ES5372.1-B has various plug connectors for internal and external connec-
tions. The positions of the plug connectors are shown in Fig. 2-3.
The ES5372.1-B and plugged-in boards are supplied with voltage via the back-
plane of the ES5300.1-A Housing or the ES5300.1-B Housing. The electrical con-
nection is done via plug connector CO402 (see "Backplane Connector CO402"
on page 31).
CO201 is used to connect the ES4455.2 or the ES4456.2 with the ES5372.1-B.
All signals and load channels are connected to X1. In particular, X1 is used for
connection to the following:
• External loads
• ECU
• ES5340.2-ICE for calibrating the injection signals (I_Dig_outx)
• Oscilloscope to the analog output for the online probe
If combined with ES4456.2, the load channels are connected to X2.
The pin assignment of the plug connections is located in "Connections and Plug
Connections" on page 31.
2.2
Fuses
The voltages of the backplane of the ES5300.1-A Housing or the ES5300.1-B
Housing are protected by four fuses on the ES5372.1-B. Two additional fuses
FU100 can be installed for protecting external battery voltages (reference
ground - VBAT).
Fig. 2-5 on page 24 shows the position of the fuses. Tab. 2-1 on page 24 lists
the fuses with specification.
In case of a fuse defect, we recommend sending the board to ETAS for further
testing. For this purpose, you should send the device to ETAS (see "ETAS Contact
Addresses" on page 43).
If a fuse trips multiple times, the device must be sent to ETAS.
.
WARNING!
Fire hazard!
Use only fuses that meet the specification in Tab. 2-1 on page 24!
Never bridge defective fuses!
Failure to observe the fuse specification can lead to excess currents,
short circuits and fires.
CAUTION!
Replace fuses only with ES5372.1 Carrier Board removed!
Observe "Installation / Removal of the ES5300.1-B into / from the
ES5300.1-A Housing and ES5300.1-B Housing" on page 27 for this
purpose.
