INSTALLATION
Figure 1 shows the connection outline of the device:
Figure 1
Schematic diagram.
Z70 v2 is connected to the KNX bus through the built-in terminal (7). An external
DC
power
supply
(24V / 29V) which delivers at least 200 mA of current is also required. The KNX power
and the external power must be provided by separate supplies, in order to avoid interference to
the KNX bus. This external power must be supplied to the device through the corresponding
terminal (4) provided within the original packaging.
Note
:
although the device will not turn functional until it is powered with the external supply, the
KNX bus power should be enough to perform downloads from ETS (application program, group
addresses, etc.)
.
A short press on the
Prog./Test button
(5) will make the device enter the programming mode.
The
Prog./Test LED
(6) will then light in red. On the contrary, if this button is held while the
device gets connected to the bus, Z70 v2 will enter the
safe mode
. In such case, the
programming LED will blink in red colour.
Firmware updates (see section 2.1.9) can be performed through the Micro-USB (8) connector.
It is important to take into account that USB memories must be formatted in FAT32.
