IMPORTANT INVERTER SAFETY INSTRUCTIONS
WARNING!
Do not touch the PV panels or any rail system connected when the inverter switch is ON, unless
grounded.
WARNING!
SafeDC complies with IEC60947-3 when installing the system with a worst case SafeDC voltage (under
fault conditions) < 120V.
The worst case voltage is defined as: Voc,max+ (String Length-1)*1V,where:
Voc,max = Maximum Voc (at lowest temperature) of the PV module in the string (for a string with
l
multiple module models, use the max value)
String Length = number of power optimizers in the string
l
CAUTION!
This unit must be operated according to the technical specification datasheet provided with the unit.
CAUTION!
HEAVY OBJECT. To avoid muscle strain or back injury, use proper lifting techniques, and if required - a
lifting aid.
NOTE
Use PV modules rated according to IEC 61730 class A.

NOTE
A SolarEdge inverter may be installed in a site with a generator, however must not operate at the same
time as the generator. Operating an inverter and a generator simultaneously will void the warranty.
SolarEdge requires installing a physical or electronic interlock, which will prevent the generator and
inverter from operating simultaneously. Interlock procurement, installation, maintenance and support
are the responsibility of the installer. Damage to the inverter due to incorrect interlock installation or use
of an interlock that is incompatible with the SolarEdge system will render the SolarEdge warranty
invalid.
NOTE
The following warning symbols appear on the inverter warning label:

Risk of electric shock
Risk of electric shock from energy stored in the capacitor. Do not remove cover
until 5 minutes after disconnecting all sources of supply.
Hot surface – To reduce the risk of burns, do not touch.
