Cable installation
•
Before starting, check that none of the components of the AC drive is live. Read carefully the
warnings in chapter 1.
•
Place the motor cables sufficiently far from other cables.
•
Avoid placing the motor cables in long parallel lines with other cables.
•
If the motor cables run in parallel with other cables note the minimum distances between
the motor cables and other cables given in table below.
•
The given distances also apply between the motor cables and signal cables of other systems.
•
The
maximum lengths of motor cables
(shielded) are 100 m (MM4) and 150 m (MM5 and
MM6).
•
The motor cables should cross other cables at an angle of 90 degrees.
•
If cable insulation checks are needed, see chapter Cable and motor insulation checks.
Start the cable installation according to the instructions below:
