Procedure
1. Check the requirements related to lengths, distances, and positioning of the cables according to instructions in
6.5.1 Additional
Instructions for Cable Installation .
2. Follow the installation instructions of the correct enclosure size. To check the enclosure size of the AC drive, see 3.5 Enclosure
Sizes .

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 11 ).
• The distances are also valid between the motor cables and the signal cables of other systems.
• The maximum lengths of shielded motor cables are 300 m (984 ft) (AC drives with power greater than 1.5 kW or 2 hp), and 100 m
(328 ft) (AC drives with power from 0.75 kW to 1.5 kW or 1–2 hp). If the used motor cables are longer, speak to the factory to get
more information.
Each parallel cable adds to the total length.
NOTICE
If long motor cables are used (maximum 100 m or 328 ft) together with small drives (≤1.5 kW or ≤2.01 hp), the capacitive
current in the motor cable can increase the measured motor current compared to the actual motor current. Consider it
when setting up the motor stall protection functions.
• If the cable insulation checks are necessary, see 9.3 Measuring the Cable and Motor Insulation .
