Signal input: external monitoring equipment

If, at terminals X21.9/10 (see Chapter 3.4.1, page 27), there is an external

switching signal (230 V

down command, the central inverter isolates itself immediately from the
grid. Please note:
The auxiliary power supply is still present.
|
Assign terminals X21.9/10, if
section switches or power disconnectors are used, or
|
no dynamic grid support (fault ride through) is required, or
|
an external grid monitoring unit (section fuse) should shut the central
|
inverter down.
Please note:
Rapid shut-down is not the same as disconnection.
|
The auxiliary power supply is still present.
|
If the medium-voltage switching device is connected by an external
|
grid monitoring unit (section fuse), the section fuse must shut the
central inverter down in advance.
Please discuss the design of the rapid shut-down with the responsible
|
energy supply company.
