4.3 Electrical diagrams
4.3.1 Wiring code
• The main circuits are not shown in the wiring diagrams
for transparency. The control circuit is presented as a
typical circuit diagram and is a combination of numbered
basic diagrams for drives, trips and indicators.
• Using the key numbers of the basic plan, you can derive
the number of the complete diagram.
• WARNING: Some non standard electrical circuits do not
comply with the diagrams in this instruction. Such circuits
are coded with unique numbers i.e 36/0033. In such a
case an appendix to this instruction is delivered, which
contains relevant electrical diagrams.

1) These relays are part of internal closing stop circuit.
It is a 24 V DC closed circuit, through all PCBs in the box,
except SEL. Serial connection of all relays is realized
through connections ( :5/:6) in each PCB. This circuit
provides priority of a tripping signal over a closing signal.
Additionally it prevents from closing the internal supply
24 V DC lost at UVR PCB or NEKO PCB.
