5.3 Establishing equipotential bonding
The equipotential bonding consists of an electrically-conductive connection from the suction cup via
the operator handle, lift tube, rotary connection, vacuum supply hose, dust filter, ejector, compressed
air hose, and crane system to the customer-supplied connection point for equipotential bonding.
Additional grounding wires should be installed on all moving parts.
5.3.1 Grounding points
Provide all connection points for grounding wires with a low resistance grounding. The connection
points are labeled.
Ensure that any original accessory installed subsequently (see chapter 2.15) is provided with a low
resistance grounding.
WARNING
