6.5 Installation of Cables
6.5.1 Additional Instructions for Cable Installation
• Before starting, make sure that none of the components of the AC drive is live. Read carefully the warnings in Safety section.
• Make sure that the motor cables are sufficiently far from other cables.
• The motor cables must go across other cables at an angle of 90°.
• If it is possible, do not put the motor cables in long parallel lines with other cables.
• If the motor cables are in parallel with other cables, obey the minimum distances (see table 15).
• The distances are also valid between the motor cables and the signal cables of other systems.
• The maximum lengths of shielded motor cables are 100 m/328 ft (for MR4), 150 m/492 ft (for MR5 and MR6), and 200 m/656 ft (for
MR7, MR8, and MR9).
• If the cable insulation checks are necessary, see
8.3 Measuring the Cable and Motor Insulation.
