Dissipation of electrical charges between vehicle support frames (vehicle mass) and a
ground potential (ESD protection) is permitted.
Grounding mobile MOVITRANS
®
systems in zones with a protective grounding meas-
ure does not cause an increased risk potential and is consequently permitted.
The insulation capacity of the equipment and the effectiveness of the equipotential
bonding are to be confirmed within the context of the cyclic system checks at mobile
parts and at the complete system for operations at IT networks.
Rule out possible potential transfers on the mobile parts, for example on individual ve-
hicles, by external equipment when planning and operating the systems.
ESD protection
In order to ensure optimal protection against electrostatic discharge (ESD), measures
must be taken for all places where non-conductive surfaces rub against one another to
ensure that charges are dissipated.
This is particularly important for mobile systems such as lifting gears, floor conveyor
vehicles, floor conveyor systems, etc.
You can dissipate charges as follows:
• Via conductive component parts, such as:
– Combs
– Brushes
– Springs
– Sliders
• With conductive track rollers or wheels
• With conductive floor coverings or work areas
The following figure shows the potential methods for ESD protection:
