•
Lay signal lines separately from the load resistance lines because of
the occurrence of interference.
•
Transmit analog signals (e.g. command values, actual values) via
shielded lines.
•
Do not connect mains, DC bus or power leads to low voltages or allow
them to come into contact with these.
•
When carrying out a high voltage test or an applied-overvoltage
withstand test on the machine’s electrical equipment, disconnect all
connections to the devices. This protects the electronic components
(allowed in accordance with EN 60204-1). During their routine testing,
Rexroth drive components are tested for high voltage and insulation in
accordance with EN 50178.
CAUTION
Risk of damage to the drive controller by
connecting and disconnecting live connections!
⇒
Do not connect and disconnect live connections.
