KEB COMBIVERT F6 Instructions For Use Manual - 5 Electrical Installation
5 electrical Installation
5.1 General information
This chapter contains the information which must be observed when selecting the ca-
bles, the protective measures, as well as the cable routing in the control cabinet.
ATTENTION
The applicable laws and local regulations must always be observed
when planning and executing the installation. KEB assumes no liability
for installations when laws, local and / or other regulations have not
been complied. If the recommendations provided by KEB have been
ignored, there can be problems when using the drive converter which
are not covered by the warranty.
The indicated conductor cross sections in chapter „Technical Data“ are recommenda-
tions for the dimensioning and serve as standard values for multicore copper power
cables. They are valid for a maximum ambient temperature of 40°C and open laying
cables. This must be taken into account accordingly in case of deviating ambient condi-
tions and local regulations.
5.2 Laying the cables
• Lay cables being susceptible to interference or sources of interference at the high-
est possible distance from each other (min. 200 mm).
• If the distance is not complied with, additional shielding measures shall be provided.
• Cables must be placed as close as possible to grounded housing parts, mounting
plates or cabinet frames. This reduces noise emissions and noise injection.
• Crossings of cables with signals of different classes must be avoided.
• If another cable laying is not possible, cross the cables in a right angle, especially if
it concerns to sensitive and interfering signals.
• Cores of signal and data cables which are not used must be grounded at both ends.
• Avoid long cables and interference sources in order to prevent additional coupling
points in the cabinet system.
• Not used cables must be grounded on one side in the control cabinet.
• Make ground connections with the largest possible cross-section to further control
cabinets, system components and decentralized devices.
• Avoid larger cable loops.
