Power Supply Using A Dual Power Supply - Siemens SENTRON ATC6500 Manual

7.1.2

Power supply using a dual power supply

Using a dual power supply, such as the 3KC9625-1 dual power supply, it is possible to
switch between two power supplies.
In this case, the additional accessory is necessary. In this way, the ATC is supplied by two
230 V AC networks. If Source 2 is fed by a generator, the ATC will fail during a transfer. And
it will fail until the generator is started and has reached the required voltage quality.
Note
Technical specifications of the supply voltage
When a dual network connection is used, the technical specifications for the supply voltage
of the ATC6500 must be observed (see chapter Connecting the power supply of the
ATC6500 (Page 83)) as well as the technical specifications of the additional dual network
connection.
Additional information is available in the Operating Instructions for 3KC9625-1
(https://support.industry.siemens.com/cs/ww/en/view/109738022).
