Safety
General This manual contains important instructions for the inverter that must be followed during
installation and maintenance of the inverter.
The inverter is designed and tested according to international safety requirements. Due
to its electrical and electronic components, certain precautions must be taken when
installing and operating the inverter.
In order to reduce the risk of injury to persons and to ensure safe installation and opera-
tion of the inverter, be sure to read these Operating Instructions carefully and follow all
instructions and safety instructions.
Failure to observe the Operating Instructions and safety instructions can void the war-
ranty and/or cause damage to the inverters or other property damage!
Electrical installa-
tions
All electrical installations must be carried out in accordance with the National Electrical
Code, ANSI/NFPA 70, and any other codes and regulations applicable to the installation
site.
For installations in Canada, the installations must be done in accordance with applicable
Canadian standards.
Rapid shutdown The rapid shutdown (RSD) can be triggered via loss of the grid connection: If the AC
connection is lost, a rapid shutdown can be performed automatically. The inverter detects
a loss of the AC connection and the lines are discharged to < 30 VDC / 8 A / 240 VA and
< 15 VAC / 8 A / 240 VA. The inverter also interrupts the communication to the PV mod-
ules if they comply with the SunSpec standard for Rapid Shutdown.
In case a module-level shutdown equipment within the PV array is used in combination
with the inverter, this labeling has to be used according to NEC (Section 690.12), CEC
(64-218):
SOLAR PV SYSTEM IS EQUIPPED
WITH RAPID SHUTDOWN.

In case a string-level shutdown equipment at the PV array is used in combination with
the inverter, this labeling has to be used according to NEC (Section 690.12), CEC
(64-218).
