Remove mains plug before working on the electrical system of the working platform.
Discontinue operation immediately if faults occur that endanger operational safety!
Check the following if there are faults:
-
Mains supply plugged in?
-
Fuses in the building site main cabinet? (16 A, slow-to-blow)
-
Correct extension cable?
-
Cable cross section for extension cable at least 3x2.5 mm
2
with alternating current or at least 5x2.5
mm
2
with three-phase current
-
Is the EMERGENCY STOP button unlocked?
-
Has the rope stop engaged?
-
Automatic safety features in the switch box of the central control.
-
Is the overload switch pressed down? (red indicator light(s) on the control cabinet)
