7.1.3 VARAN Wiring Guidelines
Since the components are supplied with power through VARAN, the maximum cable length
(without new 24 V supply is highly dependent on the cross section of the VARAN cable and
the number of connected modules.
The voltage can be supplied (switchable via the software) to the following
modules over the RJ45 connector of the VARAN Out port.
This does NOT comply with the VARAN specification.
The supply voltage of the VARAN Out port to the SV 142 can only then be
turned on when the respective port is connected to a VARAN module that is
suited of a 24 V supply (e.g.: PVDM 08x, PVAI 011, VEB 02x,...).
CAUTION!
VARAN modules, which are not suitable for the supply over VARAN, can be
damaged when connected to modules with an active power supply.
