Attention!
If local regulations require the installation of a residual current operated protective device, the following applies:
In case of a fault the drive controller is able to generate d.c. leak currents without zero crossing. Drive controllers
there fore must only be operated with RCDs

) type B for a.c. fault currents, pulsating or smooth d.c. fault currents,
which are suitable for servo controller operation, see IEC 60755. RCMs

purposes.

Note the following points:
• Switching the mains power:
– In case of too frequent switching the unit protects itself by high-resistance isolation from the system. After a
rest phase of a few minutes the device is ready to start once again.
• TN and TT network: Operation is permitted if:
– in the case of single-phase devices for 1 x 230 V AC the supply system conforms to the maximum overvoltage
category III as per EN 61800-5-1.
– In the case of three-phase devices with external conductor voltages 3 x 230 V AC, 3 x 400 V AC, 3 x 460 V AC and 3 x
480 V AC
1. the neutral point of the supply system
is grounded
and
2. the supply system conforms to the maximum overvoltage category III as per EN 61800-5-1 at a system
voltage (external conductor neutral point) of maximum 277 V.
• IT network: not permitted!
– In case of a ground fault the electrical stress is approximately twice as high. Clearances and creepages to EN
61800-5-1 are no longer maintained.
• Connection of the drive controllers by way of a line reactor is mandatory:
– where the drive controller is used in applications with disturbance variables corresponding to environment class
3, as per EN 61000-2-4 and above (hostile industrial environment);
– in the case of single-phase mains supply;
– for compliance with EN 61800-3 or IEC 61800-3.
• For further information on permissible current loads, technical data and ambient conditions please refer to the
appendix.
Note:
Please be aware that the YukonDrive® is not rated for environment class 3. Further measures are essential in order for
that environment class to be attained! For further information please consult your project engineer.
