Instructions for Use
Sizing of Enclosure and Control Cabinet
• 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.
Risk of damage to the drive controller by
connecting and disconnecting live connections!
Do not connect and disconnect live connections.

CAUTION
Control Cabinet with Multiple-Line Structure
Note:
Particular attention should be paid to the maximum allowed air
intake temperature of components when they are arranged in
multiple lines in the control cabinet. Where necessary, cooling
air guides are to be provided with blowers specially used for
this purpose.
