6. Other applications
6.1 Series connection
It is possible to connect multiple units of the same
type to a series connection if these rules are follo-
wed:
• No master-slave operation
• The grounds of the analog interfaces MUST NOT
be connected to each other. This also applies for
any other signal on the analog interfaces. If remote
control is required, it can be done using galvanic
isolation amplifiers and by controlling all units in
parallel.
• Any load current leading conductor must be
dimensioned for the maximum output current of
the unit with the highest nominal output current.
• No negative DC output pole of any device may
have a potential >300V against earth (PE).
6.2 Parallel operation
The parallel connection and operation of multiple
identical units is basically possible, but not explici-
tely supported. Due to the overvoltage protection
level that follows the adjusted output voltage, it is
not possible to use the analog interface to create a
master-slave-like system or to use the Share Bus
for load current distribution.
