Fronius Primo GEN24 Series User Manual

Surge protective device (SPD)
General A surge protective device (SPD) protects against temporary overvoltages and dis-
sipates surge currents (e.g. lightning strike). Building on an overall lightning pro-
tection concept, the SPD helps to protect your PV system components.
For detailed information on the wiring diagram of the surge protective device, see
chapter Surge protective device (SPD) on page 228.
If the surge protective device is triggered, the colour of the indicator changes
from green to red (mechanical display) and the operation LED of the inverter
lights up red (see chapter Button functions and LED status indicator on page
35). The error code "1030 WSD Open" is displayed on the user interface of the
inverter in the "System" → "Event Log" menu or in the user menu under "Notific-
ations" as well as in Fronius Solar.web. In this case, the inverter must be repaired
by an authorised specialist.
IMPORTANT!
The inverter also switches off if the 2-pin signal cable of the surge protective
device is interrupted or damaged.
External surge protective device
To receive notification when external surge protective devices are triggered, it is
recommended to connect the feedback contacts in series to the WSD input.
Safety
WARNING!
Danger due to electrical voltage on live parts of the photovoltaic system.
This can result in serious injury and damage to property.
▶
Disconnect live parts of the photovoltaic system on all pins and on all sides.
▶
Secure against re-activation in accordance with national regulations.
▶
Allow the capacitors of the inverter to discharge (2 minutes).
▶
Check that the inverter is de-energised with a suitable measuring device.
WARNING!
Danger due to work that has been carried out incorrectly.
This can result in serious injury and damage to property.
▶
Installing and connecting an option must only be carried out by service per-
sonnel trained by Fronius and only within the scope of the respective tech-
nical regulations.
▶
Follow the safety rules.
Scope of supply The surge protective device (SPD) is an optional extra and can be retrofitted to
the inverter.
