8 Installation and Maintenance
8.1 Mechanical Installation of the IndraControl L40
Mount the IndraControl L40 to a mounting rail (standard top-hat rail)
according to DIN EN 50022 (35 mm x 7.5 mm).
Note: Ensure that the top-hat rail is attached such that it provides
appropriate rigidity.
In addition to its holding function, this top-hat rail also
assumes the function of ground connection and heat removal.
For that reason, the top-hat rail must be connected to a functional earth
ground. In connection with the metal bottom frame of the IndraControl
L40, the top-hat rail is furthermore provided as heat sink.
Note: Ensure a well heat-dissipating connection to the rear panel of
the switch cabinet.
Install the IndraControl L40 horizontally in a switch cabinet or an
appropriate housing.
If permitted by ambient conditions, the IndraControl L40 can also be
mounted directly to the system.
CAUTION
Do not mount controls, modules or connectors
while the unit is live!
⇒
Before mounting or dismounting components of the
station, de-energize the entire station.
Connect the voltage only after you have set up the
entire station. Any non-observance of this
requirement may cause destruction of components.
Mounting the IndraControl L40
Mount the IndraControl L40 by hanging it onto the top-hat rail from above
and then exerting slight pressure to engage the control in the lower
section of the housing.
If necessary, mount Rexroth Inline modules in series with the control. For
more detailed information, please refer to the Section "Mechanical
Installation of Rexroth Inline Modules" on page 8-3.
The end plate must form the mechanical termination to the right of the
station, irrespective of whether you have mounted Rexroth Inline modules
in series or not. The end plate does not have any electrical function. It is
intended to protect the station from ESD pulses and the user from
dangerous contact voltages. The end plate is included in the scope of
delivery of the IndraControl L40. It is, therefore, not necessary to order the
end plate separately.
Thereafter, place the function modules onto the top-hat rail as necessary
to the left of the IndraControl L40. Slide the function modules along the
top-hat rail all the way to the left side of the IndraControl L40, until you
have established a secure connection via the PCI
PLUS
bus.
