Step Action Comment
1
Define the wire cross-section
dependent on the maximum current and
ambient temperature.
Wire cross-section to VDE0100,
part 523
2
Wire the CDD3000-HF drive controller
with the mains filter, max. line length
0.3 m (with unshielded cable)!
Step not applicable for BG1 to
BG4; up to 11.8 kVA the mains
filter is built-in.
3
Wire the line choke
1)
.
Reduces the voltage distortions
(THD) in the system and extends
the service life.
4
Install a circuit-breaker K1 (power
switch, contactor, etc.).
Do not connect the power!
5
Use mains fuses (type gL) or miniature
circuit-breakers (trip characteristic C) to
cut the mains power to all poles of the
CDD3000-HF drive controller.
To protect the cable in
accordance with VDE guidelines
1)
See appendix A.4.
Connection of the CDD3000-HF drive controller via a line choke with a short circuit
voltage of 4 % of the mains voltage (u
k
= 4 %) is obligatory:
1.
Where the CDD3000-HF drive controller is used in applications with interference
corresponding to environment class 3, as per EN 61000-2-4 and above (hostile
industrial environment).
3.
Where there is a requirement to comply with the limit values for variable-speed
electric drives (see standard EN 61800-3/ IEC 1800-3)
4.
Where there is a dc link between multiple CDD3000-HF drive controller.
