NOTICE
Damage to the device due to improper transport
Improper transport can cause mechanical loads on the housing or busbars which can result
in damage to the device.
• Use a lifting harness with vertical ropes or chains during transport.
• Do not use the busbars as handles or for fastening a lifting harness.
• Only tighten the crane lifting lugs by hand. Remove the crane lifting lugs after the
Screw coupling points for mechanical support
Since the Active Line Modules are housed in a very slim enclosure, they need to be
mechanically supported against lateral movement and vibration if they are installed in a
control cabinet. Screw coupling points are provided on the top and bottom of the units for this
purpose.
If several modules are mounted adjacent to one another, they can be interconnected via the
screw coupling points. When a single module is installed, lateral support can be provided by
means of reinforcing plates inserted between the module and the cabinet.
Protection guard
A protection guard is mounted on the bottom of the Active Line Module ("1" in the diagram
below) for use during transportation. The Active Line Module can be rested on this protection
guard while it is removed from the packaging and during transportation.
Before the module is installed at its final location, this guard must be removed. To do this,
remove the four screws ("2" in the diagram) and remove the guard.
Risk of injury due to toppling when placing down on the protection guard
A module placed down on the protection guard can topple over therefore causing injury.
• When the module is placed down on the production guard, ensure that it cannot topple
