0 external line voltage
1) Type AC305/360 : (see diagram 2-2i)
The auto transformer for the power unit blower is
connected to the internal line voltage via wire
jumper at terminals 2L1 – 460 (Default setting:
460 V) and protected by fuses F4, F5.
For line voltage 400 V the wire jumper must
be set to terminals 2L1 – 400.
2) Type DC360: (see diagram 2-2j)
The external single phase supply line voltage 400
or 460 V must be connected to the appropriate
terminals 400 – 0, or 460 – 0 and protected. (p.ex.
through thermal magnetic circuit breaker).

/1 AC-line choke if permissive fault current capacity
is exceeded (see tables 2-1 and 5-1)
/2 If the resistor overheats, this contact operates a
disconnect that removes AC power from the drive.
