8 Functional description Power Supply modules
The power supply module AN is offered as option and contains all components that are
required for the power-side feed-in of the AMKASYN drive system.
The supply for generating the DC-BUS voltage is provided to the AZ module through the
main fuses F1, F2, F3, the main contactor K1 and the line reactor KD. The feed of the
switched mode power supply in the AZ module, fused via F4, F5, F6 is branched off before
the main contactor.
In the power supply module AN xxF a mains suppression filter is additionally integrated
which guarantees the conformity of the radio interference voltage’s limiting values according
to class A (EN 5501) for the AMKASYN system. It must however be provided, that cabling,
shielding and earthing are executed as instructed.
The AC voltage for the fans in the modules (230V, see „AN... specifications“) must be
provided by the customer at the terminals X03. F7 and F8 fuse the fan circuit.
On the power side, the terminals X06 in the AN module must be connected with the terminals
X26 in the AZ module. Insert plug-in terminal block X05 in the plug connector X25 and the
fan cable in socket X33.
If the power supply module AN option is not used, the corresponding components (fuses,
main contactor, line reactor) must be procured, installed and wired by the customer.
A main contactor with a pickup time of < 100 ms is required.
