The terminals 23 and 24 are short-circuit proof.
Terminal 23 is at the top when installed.
Table 7-6 Control terminal strip X103
Either an OP1S or a PC can be connected up via the 9-pole SUB D
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.
