2.3 Power connections
2.3.1 Mains connection
In general
The inverters must be connected to the mains according to VDE
regulations, so that they can be isolated from the mains at any time with
appropriate releasing devices e.g main switches.
Note:
Once the inverter is connected to the mains, the internal DC-link is then
loaded. This means that the inverter is not ready for operation until a certain
switch-on delay has elapsed. Hence mains connection can only be
repeated at long time intervals (at least 60 s). Jogging operation with
the mains protection is not possible.
Caution:
Due to the high current flows (> 3.5 mA) the use of fault current breakers
on their own is not permissible. Hence a ground line is urgently prescribed.
The mains fusing must be laid out, according to the current loading of the
connecting cable according to DIN 57100 (see recommendation in the
power table). When using circuit breakers, only those with triggering
characteristics B or C can be employed.
VF1205M, VF1207M connection
The mains connection (1 x 230 V) is via terminals L1, N,
.
Technical data see data table.
Caution!
Never connect 400/460 V to terminals L1 and N. The device would be
destroyed by the excess voltage.
VF1404M ... VF1410M connection
The mains connection (3 x 400/460V) is via terminals
L1, L2, L3, . Technical data see data table.
