Other information
Along with any of the above selected circuit diagrams, Appendix B, ‘Circuit diagram 1’
must always be used when connecting the suction trolley return unit.
Get a good idea of how the electrical system is designed by identifying the integral
electrical components in Appendix A, Cable connections overview where the cables are
identified by the designations W1–W16.
It is assumed that the connection boxes C_BOX_1 and C_BOX_2 and Drive unit are
fitted, and that disconnection arrow SLX1 has been positioned at the desired location in
consultation with the customer.
Bus bar SLX3 must be aligned so that the driving slot’s current collector has good
contact with the bottom of the bus bar and that the current collectors run without
resistance along the bus bar.
Check that the magnetic sensor SL2 is fitted about 0.7 metres in front of the disconnection
arrow SLX1.
WARNING!
Risk of electric shock!
The power supply must be disconnected from the drive unit. If the power supply cable is
already installed to the drive unit then the power supply must be disconnected from the
drive unit. Switch off the working switch and lock the knob with a padlock, and mark
this with the sign “Work in progress”.
Cable W2

Route the cable W1 into connection box 1 and connect in accordance with Appendix
B, ‘Circuit diagram 2’.
2.
Route the cable over the extraction channel.
3.
Drill a 4.5 mm hole in the top of the channel, press in a fastener and affix the cable.
4.
Route the cable through the fitting on the drive unit.
5.
Adapt the length of the cable so that the drive unit can be loosened and placed on top
of extraction channel during service.
6.
