2.4.1.3 Line fuses for Installation instructions for a 3AC 8230 frequency inverter connection in the
operation class gL and customer’s low voltage distribution system:
cable cross-sections The NH fuses recommended for operation class gL and the cable cross-sections to be
used for 8230 frequency inverter 3AC mains connections are shown in the following
table. Minimum cross-sections for mains supplies cables with PVC insulation
according to EN 60204-1:1992 are given for an ambient temperature of
ϑ
= 40 °C and

2.4.1.4 Fuse circuit breakers The above semiconductor fuses (aR-Characteristics) with 100 mm length to
DIN 43 653 can be installed as an alternative to fuse bases in conjunction with the
hand-operated fuse circuit breaker.
This creates a separation point in the 3AC mains supply and all poles of the
semiconductor fuses can be switched.
2.4.1.5 Mains contactor Contactors 3 AC 400 V, 50/60 Hz
On 3AC mains supplies which include (automatic) on/off switching of the mains
voltage at the 8230 frequency inverter input (eg. 8230 frequency inverter units with
optional brake chopper and braking resistor), 3-phase contactors according to the
following tables are used.
