DANGER : ELECTRICAL HAZARD!!
- To avoid shock hazard during cabling, insure any live grid connections are
removed from the inverter.
- Wire sizes chosen for the AC conductors must meet ampacity requirements of
NEC Section 310 or equivalent.
- Wiring method for the AC Installation must comply with the local electrical code.
- Failure to follow the instructions may result in damage to the inverter and AC
conductors.
CAUTION : INVERTER AND EQUIPMENT DAMAGE MAY OCCUR !
WARNING !
- Installation and commissioning must be performed by a well-trained person
(e.g.a licensed electrician) in accordance with local, state, and National Electrical
Code ANSI / NFPA 70 requirements.
- Input and output circuits of this unit are isolated from the enclosure System
grounding must be done in accordance with the National Electrical Code (NEC).
- Compliance to the local electrical code is the installer's responsibility.
- Inverter warranty void if the DC input voltage exceeds 1000 Vdc.
-
The M80/60U solar Inverters must be connected to a 3-phase 480 Vac utility service.
NEC 705.12(D)(1) requires that the inverter (every fixed appliance) must be
connected to a separate, dedicated circuit breaker (or other approved OCPD)
with no other outlets or devices connected to the same circuit (not shared by
any other appliance).
CAUTION : POINT OF CONNECTION !
- This inverter may be damaged due to moisture or dust intrusion.
DO NOT OPEN the power module section of the inverter.
ATTENTION
3.3 Electrical Installation for AC Wiring
- In order not to damage the components in the inverter, ensure the correct
conductor is connected to the appropriate AC switch on the inverter.
CAUTION: WRONG AC WIRING !
For first time installing/re-installing WB cover, in order to guarantee proper
long-term operation of the inverter, procedures in Section 5.1 must be followed.
