5. All light curtains must be connected directly with an
equipotential bonding strip from the grounding screw
via a grounding cable.
The rail is ideally fastened to the light grid portal.
A grounding cable is laid from the equipotential bonding
strip to the ground of the control cabinet.
6. Rout the grounding cable from the ground terminal
on the "Quattro" control section to the equipotential
bonding strip.
7. As the portal pro les are made of anodized aluminum,
grounding via sliding blocks is insu cient.
Connect all pro les with each other via short grounding
cables and then with the equipotential bonding strip.
8. Connect the shield of the Pro bus cable on the "Quattro"
control section to pin 3 of the green plug.
9. Additional information:
To keep the gap in the sensing eld at the feed slot as
small as possible, turn the fastening brackets of the
upper light curtains inwards.
