Instructions for Use
5.3.2
Sizing of Enclosure and Control Cabinet
Multiple-Line Design of the Control Cabinet
●
The human body (ground connection by touching a conductive, groun‐
ded object)
●
Parts and tools (place them on a conductive support)
Endangered components may only be stored or dispatched in conductive
packaging.
Rexroth connection diagrams are only to be used for producing
installation circuit diagrams! The machine manufacturer's installa‐
tion circuit diagrams must be used for wiring the installation!
●
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 shiel‐
ded lines.
●
Do not connect mains, DC bus or power cores to low voltages or allow
them to come into contact with these.
●
When carrying out a high voltage test or an applied-overvoltage with‐
stand test on the machine's electrical equipment, disconnect all connec‐
tions 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 (in accordance with EN
61800-5-1:2007, section 5.2.3.2) and insulation (in accordance with EN
60204-1:2006, section 18.3).
NOTICE
Do not connect and disconnect live connections.
Arrangement of the devices, air guides/drip protections, fans
Pay particular attention to the maximum allowed air intake tem‐
perature of devices when they are arranged in multiple lines in the
control cabinet.
If possible, place devices with a high degree of power dissipation
(e.g. supply units with braking resistors, DC bus resistor units)
●
in the top line and
●
near the outlet air aperture to the cooling unit
Mount air guides between the lines to
●
protect the devices in the upper lines against the warm outlet
air of the devices beneath and
●
protect the devices beneath against penetration of liquids
(e.g. dripping condensation water or leaking cooling liquid)
Additional fans convey the outlet air to the cooling unit and cool‐
ing air to the upper lines.
At the installed control cabinet, check the air intake temperature
of all devices.
