3.3 System Bus
3.3.1 Electrical Connection of the Modules
Every module of the ES800 system is equipped with a system connector on both
the top and bottom. When stacked, the system connectors of the modules are
directly connected to one another.
When stacking the modules, all electrical connections between the modules
(power supply and bus systems) are established without cables.
3.3.2 Protection of System Connectors
The system connectors are located at the rear end of the module housing at the
top and bottom in each case. If the upper part of the system connector of a module
is not used, it is protected by a flap.
Only transport and store the product with the protective flap closed and the pro-
tective cap attached.
3.4 Power Supply
The modules of the ES800 system are supplied with operating voltage by an ES800
Base Module jointly via the system connector of the modules. The ES800 Base
Module is installed on the underside of an individual module or on the underside of
a module stack. The connection to the power supply is established via the system
connector on the underside of the lowest module.
NOTE
Hints for positioning the module types in the module stack can be found in chap-
ter 13.3 on page 114.
NOTE
The connection of the modules to the vehicle battery or the lab power supply
may only be performed with a module approved for the power supply to the
ES800 modules (e.g. ES801.1). A direct connection to the power supply without
ES800 Base Module is not permitted.
NOTE
The ES800 Base Module (e.g. ES801.1) must be physically disconnected from all
operating voltages so that the ES800 system does not take on any current.
NOTE
Observe the notes on the power supply of the ES800 system in chapter 16.9.1
on page 149.
