CDD3000-HF Operation Manual
 
A.5 UL approbation
Measures to maintain UL approbation
1. Switch cabinet mounting with IP54 protection and contamination 
level 2 is mandatory.
2. The devices are only usable in systems with surge strength class III.
3. Only UL approved fuses and circuit-breakers may be used.
CDD32.xxx-HF : Mains fuses min. 250 V H or K5
CDD34.xxx-HF : Mains fuses min. 600 V H or K5
4. The devices are usable in systems with a maximum current capacity 
of 5000 A.
5. The connecting cables (mains power, motor and control cables) must 
be UL approved.
CDD32.xxx-HF : Min. 300 V cables (mains/motor), Cu 75° C min.
CDD34.xxx-HF : Min. 600 V cables (mains/motor), Cu 75° C min. 
Attention: The drive controllers can typically be overloaded with 1.8 x I
N
 
for 30 s. The effective servo capacity utilization (I
eff.
 ≤ I
N
) 
must never be greater than I
N
 (rated current).
