Contactless energy transfer
The following preventive measures protect mobile systems with MOVITRANS
®
con-
tactless energy transfer systems against electrical hazards:
• Protective separation
• ESD protection
Protective separation
Compliance with "preventive separation" in line with VDE 0100 part 410 nominal volt-
age ≤ 500 V is ensured by the following measures.
All electrical equipment on the mobile part, such as on a vehicle, must be equipoten-
tially bonded to each other.
Comply with the following rules:
• Use the vehicle support frame (vehicle GND) for the equipotential bonding.
• Use only gray or black cables for equipotential bonding.
This cable is for equipotential bonding and is not a PE connection. Therefore, you
should not use the yellow/green lead for the equipotential bonding cable as this color
is reserved for PE.

transfer with MOVITRANS

If it is required in certain production steps, temporary grounding of the vehicle support
frame is permitted.
All cables must have double basic insulation. Double insulation is also required for the
incoming cable of the pick-up. These requirements are always met when using
MOVITRANS

components.
