The specifications of chapter 3.3.5 (fuses and wire cross sections) are recommen-
dations and refer to the operation
– in cabinets and machines
– installation in cable ducts
– max. ambient tempe40°C.
•
When choosing the cross section of the wire the voltage drop under load should be
considered (refer to chapter 2.6)
•
Protection of the wires at mains side (L1, L2, L3):
– by commercial wire protection fuses.
– fuses have to be compliant with the relevant standards on site.
– rated voltage of the fuses have to be compliant with the voltage on site.
•
Protection of the power feed/feedback unit at mains side (L1, L2, L3):
– by commercial semiconductor fuses.
– fuses have to be compliant with the relevant standards on site.
– rated voltage of the fuses have to be compliant with the voltage on site.
•
Protection of the power feed/feedback unit at DC side (+UG, -UG):
– fuses are part of the power feed/feedback unit (refer to chapter 3.3.4.2).
The erector/user of the plant bears the responsibility for the observance of further
