3.3.3. Mains input current
The mains input current to the drive depends on the duty status of the controlled motor. Table 3.3.2.1
shows nominal continuous duty values (IEC 146 class 1) with typical output power factors for each
model of drive.
3.3.4. Output
The output from DVS drives is protected against short circuits between phases and to ground.
N
OTA
!
It is forbidden to connect any external voltage to the drives output terminals! Nevertheless, once a motor
has been disabled, it can be disconnected from the drive output while the drive is still functioning.
The nominal continuous output current value (I
CONT
) depends on mains voltage (Kv), ambient temperature (K
T
) and switching
frequency (K

) if higher than the default frequency:
