BA8230 19
2.4 Supply components The 8230 frequency inverter can be supplied with power through connection of the
units to a 3-phase supply.
2.4.1 Components for 3AC supply The components for connecting the 8230 frequency inverter to an AC network are
determined according to the 8230 frequency inverter type rating.
The basic components
- Semiconductor fuse recommended for brake chopper
- mains choke (2.4.1.2)
-mains fuse (2.4.1.3) with gL characteristic
are required to VDE and are shown in the tables below.
Minimum cross-sections for mains supply cables with PVC insulation to EN 60204-
1:1992 are given at an ambient temperature of ϑ = 40 °C and laying method E.
In the event that the supply includes separation points,
the additional components
- fuse isolator, 3-pole
- fuse circuit breaker (2.4.1.4)
- mains contactor / main contactor (2.4.1.3)
are to be used.
