7.9 Installing the DC link connection
If you would like to connect the SD6 drive controllers in the DC link group, you must first mount
the Quick DC-Link modules of type DL6A and then build the appropriate drive controllers over
them.
Information
Note that you cannot combine DL6A Quick DC-Link modules and RB 5000 rear section braking
resistors within a group.
DANGER!
Electrical voltage! Risk of fatal injury due to electric shock!
▪ Always switch off all power supply voltage before working on the devices!
▪ Note the discharge time of the DC link capacitors in the general technical data. You can
only determine the absence of voltage after this time period.
Tools and material
You will need:
§ 2 copper rails with a cross-section of 5 x 12mm in the correct length; see the chapter
Length of copper rails [}44]
§ The M5 threaded bolts included with the DL6A Quick DC-Link modules and the
accompanying screw and washer assemblies (screws with flat and spring washers)
§ An 8 mm hexagonal socket wrench
§ The insulation connection pieces and quick fastening clips included with the DL6A Quick
DC-Link modules
§ The insulation end sections for the left and right termination of the group that are available
separately
Requirements and installation
Perform the following steps in the specified order.
ü
In accordance with the drilling diagram, taking into consideration the various device
dimensions, you have made threaded holes for the threaded bolts on the mounting plate at
the mounting position.
ü
The mounting plate has been cleaned (free of oil, grease and swarf).
