SAVE THESE INSTRUCTIONS –This manual contains important instructions for the Three Phase Inverter with Synergy Technology that should be followed during installation
and maintenance. Using this equipment in a manner not specified in this guide by SolarEdge may impair the protection provided by this equipment.
Legend
WARNING! SYNERGY UNIT, PN: SESUK-USRxxxxx, INCLUDE A PHOTOVOLTAIC RAPID SHUTDOWN SYSTEM (PVRSS). SUCH UNITS, INCORPORATE ONE OR MORE PIECES OF
EQUIPMENT THAT EXERCISE THE RAPID SHUTDOWN CONTROL OF PV SYSTEM CONDUCTORS REQUIRED BY SECTION 690.12 OF THE NEC (NFPA 70). OTHER EQUIPMENT INSTALLED IN
OR ON THIS PV SYSTEM MAY ADVERSELY AFFECT THE OPERATION OF THIS PVRSS. IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE THAT THE COMPLETED PV SYSTEM MEETS
THE APPLICABLE RAPID SHUT DOWN FUNCTIONAL REQUIREMENTS. THIS EQUIPMENT MUST BE INSTALLED ACCORDING TO THE MANUFACTURER’S INSTALLATION INSTRUCTIONS
WARNING! Upon servicing or replacing equipment, instructions in the installation manual must be followed to maintain the integrity of the PV hazard
control system. SolarEdge commercial optimizers and three phase inverters should only be replaced with SolarEdge commercial optimizers and inverters.
Third party equipment is not compatible.
!
Turn ON/OFF the main circuit board AC switch.
When turning off, wait 5 minutes for DC Voltage to
drop to safe level before removing the front panel.
Turn the DC Disconnect Switch on/off. When turning off,
wait 5 minutes for DC Voltage to drop to safe level before
removing the front panel.
Turn the ON/OFF/P Switch on/off. When turning off, wait
5 minutes for DC Voltage to drop to safe level before
removing the front panel.
Before connecting aluminum wires to terminals:
1. Remove oxide from the exposed wires with emery paper or a steel
wire brush
2. Clean dust with a cloth and Isopropyl alcohol (IPA)
3. Coat wires with a designated antioxidant aluminum wire grease
immediately after cleaning
CAUTION!Connection of oxidize aluminum wires may result in
resistance and high temperatures at contact points. Improper
execution of the following procedure may cause damage to the unit.
