Please avoid differences in potential (e.g. due to different supply levels)
between the converters and the CC-Link master:
♦ Use equipotential bonding cables:
• 16 mm

Cu for equipotential bonding cables up to 200 m
• 25 mm
2
Cu for equipotential bonding cables over 200 m
♦ Lay the equipotential bonding cables so that there is the smallest
possible surface area between the equipotential bonding cable and
signal cables.
♦ Connect equipotential bonding conductors to the earth/protective
conductor through the largest possible surface area.
Please comply with the following instructions when laying cables:
♦ Do not lay bus cables (signal cables) directly parallel to power
cables.
♦ Lay signal cables and the associated equipotential bonding cables
with the lowest possible distance between them and on the shortest
routes.
♦ Lay power cables and signal cables in separate cable ducts.
