3.5 Electrical circuit diagram
Grounding according to local regulations
Before commissioning check whether the nominal motor
current matches the motor protection relay. Check all ter-
minal points for proper connection and that all contact
screws are tight.
Before commissioning, check all wiring and controls for
proper function. Do not permit commissioning from the
unauthorised side.
These plans were generated on a CAD system. To keep
plans to the current state, we ask that you request Nuss-
baum to make the changes.
These circuit diagrams are intellectual property. They may
not be given to third parties or reproduced without our
permission!
Rights to make changes are retained.
Circuit diagram and switch documents
Circuit diagrams were made to the best of our knowledge.
No guarantee is made for the accuracy of enclosed circuit
diagrams and switch plans contained in this document.
This is particularly relevant for switches that were complet-
ed by us according to third party plans. This was done by
us from purchaser provided manufacturer documentation.
Functional test of switch systems
Circuit diagrams are not standard documents. When
checking the control cabinet at the factory, field devices
such as sensors, thermostats and motors cannot be includ-
ed. For this reason, even with careful inspection, function-
al and switch errors cannot always be prevented.
Deficiencies are removed within the scope of guarantee
during commissioning. During commissioning, if our ser-
vices are not used, then no deficiency liability is accept-
ed. Rework, including informing of circuit diagrams of
switch systems not commissioned by us are therefore only
done to an invoice according to our service terms and
conditions. Costs for rework by third parties cannot be
honoured.

Safety inspection and safety measures
The control cabinet has been produced, set up and inspect-
ed according to recognised technology rules according
to VDE0113/VDE0100/0600 and accident prevention
regulation DGUV A3 (electrical systems and equipment)
The following tests were done:
• Voltage test and/or insulation test of the control cabinet
• Inspection of effectiveness of the safety measures used
for indirect contact
• Functional test and part test
Implemented safety measures:
Protection against direct and indirect contact
