Connecting to external emergency
stop:
If an external emergency stop is required,
it can be installed anywhere in the signal
line. When the connected emergency stop
button is pressed, the Rapid Shutdown is
started and the PV field is disconnected in
the Rapid Shutdown box. As soon as the
emergency stop button is returned to its
original position, the PV field is reconnec-
ted.
Requirements for external emergency
stop:
- Maximum switching load: 30 V DC / 5
mA
- Nominal voltage between contacts
and housing: 600 V DC

ATTENTION! ?
Wiring schemes show best practice examples assuming that more than two PV
strings connected in parallel require overcurrent protection (e.
g. fusing). Refer to Primo installation manual regarding multi conductor wiring and fusing
details
If multiple strings are connected to an MPP tracker, the string voltages should be as
equal as possible in order to avoid power losses.
