6.7 Installing the DC link connection
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. You can only determine the absence of
voltage after this time period.
Tool and material
You will need:
§ 3 copper rails with sufficient length and a cross-section of 5 x 12mm, see the chapter
Length of copper rails [
}27]
§ The nut and washer assemblies (M5) as well as the holding clamps included with the DL6B
Quick DC-Link modules
§ The insulation end sections for the left and right termination of the group that are available
separately
§ Fastening screws and tool for tightening the fastening screws
Requirements and installation
Perform the following steps in the specified order.
ü
You have tapped holes for fastening screws on the mounting plate at the installation
location in accordance with the drilling diagram and taking into consideration the different
device dimensions.
ü
The mounting plate has been cleaned (free of oil, grease and swarf).
ü
The copper rails must be straight, smooth, free of burrs and cleaned (free of oil and
grease).
1. Fasten the Quick DC-Link modules onto the mounting plate with the fastening screws.
2. Apply an insulation end section at the left edge of the first module and at the right edge of
the last module. Ensure correct alignment of the end section using the marking on the
outside and the insertion aids for the copper rails on the inside.
3. Shorten the copper rails to the correct length.
4. Clean the copper rails, especially at the contact points.
5. Insert the three copper rails one after the other and fasten them in place with two holding
clamps per rail and Quick DC-Link module. Make certain the contact points of the copper
rails do not become contaminated.
ð You have installed the Quick DC-Link. In the next step, build over the Quick DC-Link
modules with the appropriate drive controllers.
