instructions is mandatory. Failure to do so may result in injury or loss of life and

damage to the equipment.

Safety Symbols Information

The following safety symbols are used in this document. Familiarize yourself with the

symbols and their meaning before installing or operating the system.

WARNING!

Denotes a hazard. It calls attention to a procedure that, if not correctly

performed or adhered to, could result in injury or loss of life. Do not proceed

beyond a warning note until the indicated conditions are fully understood

and met.

CAUTION!

Denotes a hazard. It calls attention to a procedure that, if not correctly

performed or adhered to, could result in damage or destruction of the

product. Do not proceed beyond a caution sign until the indicated conditions

are fully understood and met.

NOTE

Denotes additional information about the current subject.

IMPORTANT SAFETY FEATURE

regulations:

NOTE

Discard this product according to local regulations or send it back to

SolarEdge.

HANDLING AND SAFETY INSTRUCTIONS 7

Three Phase Inverter with Synergy Technology Installation MAN-01-00402-1.2

IMPORTANT INVERTER SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

WARNING!

The inverter cover must be opened only after shutting off the inverter ON/OFF

switch located at the bottom of the Primary Unit, above the Connection Unit.

This disables the DC voltage inside the inverter and opens the AC relays.

Wait five minutes before opening the cover. Otherwise, there is a risk of

electric shock from energy stored in the capacitors.

WARNING!

Before operating the inverter, ensure that the inverter is grounded properly.

WARNING!

Opening the inverter and repairing or testing under power must be performed

only by qualified service personnel familiar with this inverter.

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 multiple module models, use the max

value)

String Length = number of power optimizers in the string

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.

-Three Phase Inverter with Synergy Technology Installation MAN-01-00402-1.2

8 IMPORTANT INVERTER SAFETY INSTRUCTIONS

NOTE

Use PV modules rated according to IEC 61730 class A.

NOTE

The symbol appears at grounding points on the SolarEdge equipment.

This symbol is also used in this manual.

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.
