3. Installation
Connection example (type 03)
The following diagram shows the connection of
a common 24 V supply for pins 1 and 2. Please
note that:
•
the outputs/valves must be protected against
short circuit/overload with an external 10 A
fuse
•
the supply to the electronic components and
inputs should be fused externally with 3.15 A
against short circuit/overload (recommenda-
tion)
•
the common tolerance of DC 24 V ± 10 %
must be observed
•
equalizing currents must be avoided when
both earth cables are connected, e.g. by
means of cables with appropriate cross
section as a potential compensation.
