Vacon 100 - Preparing for the Cable Installation; Cable Installation; Frames MR4 to MR7

NOTE!
The frames MR7, MR8, and MR9 have the brake chopper, only if their type
designation code has the code +DBIN. The frames MR4, MR5, and MR6 have the
brake chopper as standard.
NOTE!
The Vacon
®
100 FLOW and HVAC software do not have the dynamic braking or the
brake resistor functions.
5.5 PREPARING FOR THE CABLE INSTALLATION
•
Before you start, make sure that none of the components of the AC drive is live. Read
carefully the warnings in chapter 2 Safety.
•
Make sure that the motor cables are sufficiently far from other cables.
•
The motor cables must cross 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 20 The minimum distances between cables).
•
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 chapter 7.4 Measuring the cable and
motor insulation for instructions.
