X103 - 10 V voltage The following connections are provided on the control terminal strip:
output, SCom1,
♦ 10 V aux. voltage (max. 5 mA) for the supply of external
SCom2
♦ 2 serial interfaces SCom1 and SCom2 (USS / RS485)
Connectable cross-section: 0.14 mm
The terminals 23 and 24 are short-circuit proof.
Terminal 23 is at the top when installed.
Table 7-6
Either an OP1S or a PC can be connected up via the 9-pole SUB D
X300 - Serial
interface socket.
The 9-pole SUB D socket is internally coupled with the USS bus, with
the result that it is possible to exchange data with further converters
and inverters which are linked via the USS bus.
