Page 13: Assembly Instructions
ASSEMBLY INSTRUCTIONS Step 1. Wire AC Cable Wire the AC cable along the frame structure of photovoltaic modules. Bracket AC Trunk Cable Plug Fig.6. Wiring the AC cable Ensure that the cable matches the installation conditions, particularly in regards to the number of the modules and their orientation. The number of the Micro-inverters should not exceed the maximum number permitted for installation. -
Page 14: Step 3. Grounding The System
The Micro-inverter must be under the module, out of long-term exposure to direct sunlight or rain. Step 3. Grounding the System The system must be grounded according to local laws. The inverter can typically be earth grounded using the connector clamp secured to the chassis and an adequately- sized conductor. -
Page 15: Step 4. Fasten Ac Cable
Step 4. Fasten AC Cable Fasten the AC cable to the frame with cable ties or tie wraps. Each connector is provided with two slots for ideal fastening. If using nylon or materials that may decompose in sun light or over time, it is strongly recommended to inspect on occasion.
