8 Installation and Maintenance
8.1
Mechanical Installation of IndraControl L45/L65/L85
8.1.1 General Information
Mount the IndraControl L45/L65/L85 to a mounting rail (standard top-hat rail)
according to DIN EN 50022 (3.5 mm x 7.5 mm).
Ensure that the top-hat rail is attached such that it provides appro‐
priate 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.
Furthermore, the top-hat rail is provided as heat sink in connection with the
metal bottom frame of the IndraControl L45/L65/L85
.
Ensure a well heat-dissipating connection to the rear panel of the
control cabinet.
Mount the IndraControl L45/L65/L85
horizontally in a control cabinet or an ap‐
propriate housing.
If the ambient conditions are sufficient, the IndraControl L45/L65/L85 can be
directly installed on the plant (see chapter 4.3 "Ambient Conditions" on page
20).
Destruction of the components due to mount‐
ing
the control, module, Inline terminals, or
connectors under voltage!
NOTICE
● Before mounting or dismounting components of the station, de-energize
the entire station.
● Connect the voltage only after the entire station has been set up.
8.1.2 Mounting IndraControl L45/L65/L85
Mounting
the IndraControl L45/L65/
L85 on the Top-Hat Rail
Mount the IndraControl L45/L65/L85 by hanging it onto the top-hat rail from
above and then exerting slight pressure to engage the control in the lower sec‐
tion of the housing. Observe the minimum clearances for cooling the control,
see chapter 5.4 "Installation Notes" on page 27.
Rexroth Inline terminals added in
series
If necessary, mount Rexroth Inline terminals in series. For further information,
please refer to chapter 8.2 "Mechanical Installation of Rexroth Inline Termi‐
nals" on page 51.
End plate
The end plate must form the mechanical termination to the right of the station,
irrespective of whether Rexroth Inline terminals have been mounted in series
or not. The end plate does not have any electrical function. The end plate in‐
tended 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 In‐
draControl L45/L65/L85. Therefore it is not necessary to order the end plate
separately.
Mounting function modules
Thereafter, place the function modules onto the top-hat rail to the left of the
IndraControl L45/L65/L85, if necessary. Slide the function modules along the
