Technical Description 11
3.3 Connectors CON-L (2) and CON-S (2)
KPTC22-55 type connectors from ITT Cannon are used for signals up to 15 A.
The mating connector has a bayonet catch. Safe contact is only ensured after
the bayonet has been locked.
3.4 Jumpers
Different jumpers – 2 mm and 4 mm contacts – are employed depending on
the current specification of the signals. The 2 mm system is used for signals up
to 3 A while the 4 mm system is used for signals exceeding 3 A.
In both systems, the jumpers include center tabs that enable the user to short-
circuit signals via cable jumpers or to connect external measuring systems.
3.4.1 Signal Channel Labels
As the ES4602 Breakout panel is designed for use in combination with the
ES4500 Component Rack, the standard labels of the individual signal channels
are based on the layout of the ES4500 backplane. The signal channels relevant
to the control unit start at channel #67. The labels of the individual signal
channels are located below the associated jumper (see Figure "Location of the
Channel Label" on page 11).
Fig. 3-3 Location of the Channel Label
A customized front panel can be mounted if the user prefers different labels.
Depending on the particular type, lab jacks that are not in use can be masked.
The panel is made of 1 mm thick anodized aluminum. The labels are printed.
The panel is mounted using the existing screws.
note
The connectors CON-L (load/signal box side connectors) and CON-S (ECU side
connectors) are not protected against erroneous insertion (wrong side, etc.). The
user has to take care to insert the connectors on the correct sides.
