7.7.2 Connection to the control panel
Attention!
Note that the BUS connection now
corresponds with the BUS-2 pin allo-
cation.
If you replace a previous version of the
EU with this terminal allocation,
resolder the BUS connections.
7.6 Installation guidelines
The BUS connection lead be a shielded must
line and the core in accordance with the
diagram.
The corresponding conductor cross-sectins can
be found in the
of the installation manual
intrusion detection central unit. We would also
like to point out that the shield terminal should be
kept as short as possible, as there is otherwise a
risk of an uninentional short circuit.
Note: Do not attach a terminal resistor with connection technology. BUS
