IF GROUNDING CONDUCTOR IS EXPOSED TO PHYSICAL DAMAGE USE BARE #6 CU WIRE. GENERAL NOTES FOR SOLAREDGE GRID-TIED INVERTER 1. SYSTEM GROUNDING MEANS: SE INVERTERS ARE INTENDED TO BE INSTALLED AS PART OF A PERMANENTLY GROUNDED ELECTRICAL SYSTEM PER THE NEC ANSI/NFPA 70. AN ENGINEERED GROUND CONNECTION FOR THE INVERTER MUST BE INSTALLED AND CONNECTED TO THE UNIT AS DESCRIBED IN THE INSTALLATION MANUAL. CONNECT THE GROUND WIRE WITH THE SPECIFIED NUT AT THE MARKED PLACE IN THE WIRING BOX. GROUND CONNECTION MUST BE MADE PRIOR TO OPERATING THE UNIT. 2. CONDUITS AND CONDUCTORS: ALL INTERCONNECT WIRING AND POWER CONDUCTORS INTERFACING THE UNIT MUST BE IN ACCORDANCE WITH THE NEC ANSI/NFPA 70 AND ANY APPLICABLE LOCAL CODES. LARGE GAUGE WIRE MUST CONFORM TO THE MINIMUM BEND RADIUS SPECIFIED IN THE NEC, ARTICLE 300.34, NINTH EDITION. KEEP ALL WIRE BUNDLES AWAY FROM ANY SHARP EDGES TO AVOID DAMAGE TO WIRE INSULATION. ALL CONDUCTORS SHOULD BE RATED FOR 90 DEGREE C MINIMUM. FOR OUTDOOR INSTALLATIONS, ALL INTERCONNECT CONDUITS AND FITTINGS MUST BE NEMA-4 RATED AS REQUIRED BY THE NEC. FOR WIRE GAUGE, BOLT SIZE, AND TORQUE VALUES FOR THE DC & AC TERMINALS, SEE THE INSTALLATION MANUAL. 3. INVERTER ENCLOSURE: SE INVERTERS ARE ENCLOSED IN A MODULAR STEEL CABINET AND RATED TO NEMA 4. 4. ENVIRONMENTAL CONDITIONS: SE INVERTERS ARE DESIGNED TO BE INSTALLED IN EITHER AN INDOOR OR OUTDOOR LOCATION. ALL INVERTERS WILL BE COOLING SYSTEM. 5. OPERATOR INTERFACE CONTROLS: OPERATOR INTERFACE CONTROLS ARE LOCATED ON THE FRONT OF THE MAIN INVERTER ENCLOSURE. CONSULT THE OPERATIONS AND MAINTENANCE MANUAL FOR INSTRUCTIONS AND CODE REFERENCES. 6. ELECTRICAL SAFETY FEATURES: a. ENCLOSURE DOOR: THE SE INVERTER IS PROVIDED WITH A KEYED LOCK LOCATED ON THE FRONT DOOR TO PREVENT UNAUTHORIZED PERSONNEL FROM ACCESSING THE UNIT. b. TWO (2) DISCONNECTING DEVICES BETWEEN THE SOLAR ARRAY PANELS, THE UTILITY, AND THE UNIT ARE PROVIDED FOR THE INVERTER ENCLOSURE. THESE DISCONNECT SWITCHES ARE TO BE USED FOR ISOLATING THE SOLAR ARRAY PANELS FROM THE UNIT FOR MAINTENANCE PURPOSES AND ARE TO BE USED AS A NO-LOAD DISCONNECTING DEVICE ONLY. c. THE ANTI-ISLANDING TRIP TIME IS LESS THAN TWO (2) SECONDS AS PER UL 1741 STANDARDS. THE INVERTER UNIT WILL AUTOMATICALLY SHUT DOWN WHEN LOSS OF GRID POWER IS DETECTED. 7. PV PROTECTION DEVICE: WHEN THE SE INVERTER IS NOT OPERATING, THE PV ARRAY IS GROUNDED THROUGH A FUSED CONNECTION. THIS FUSE BLOWS WHEN A GROUND FAULT CURRENT FLOWS. WHEN THE SE INVERTER IS OPERATING, THE GROUND FAULT CONTACTOR PLACES THE POSITIVE AND NEGATIVE PV ARRAYS IN SERIES TO PRODUCE +/- VDC MAXIMUM OPEN CIRCUIT. 8. ANY ALTERATIONS TO THE SE INVERTER MUST BE CLEARED THROUGH MANUFACTURER TO MAINTAIN UL LISTING AND WARRANTY OF THE DEVICE. PLANS 6 TREATED LUMBER WOOD STUDS DRYWALL 2 X 6 R.R. 24 O.C.
