2)The symbols on the microinverter are list below and illustrated in detail. INSTALLATION WARNINGS MI-1000/MI-1200 Microinverter is designed and tested according to international safety requirements (IEC62109-1/-2, VDE4105, VDE0126, AS 4777.1 /.2& AS 3000). However, certain safety precautions must be taken when installing and operating this inverter. -
Page 6: Prepare For Installing
Prior to touching any part of the inverter use care to ensure surfaces and equipment are at touch safe temperatures and voltage potentials before proceeding. Hoymiles accepts No liability for damage from incorrect or careless operation. ... -
Page 7: Check Installation Environment
CHECK INSTALLATION ENVIRONMENT Installation of the equipment is carried out based on the system design and the place in which the equipment is installed. The installation must be carried out with the equipment disconnected from the grid (power disconnect switch open) and with the photovoltaic modules shaded or isolated. -

Assembly Diagram Fig.3. Assembly Illustration ASSEMBLY INSTRUCTION Step 1. Install Microinverter a. Mark the approximate center of each panel on the frame. b. Install the microinverter shown as below. The silver cover side should be up. Observe the certification documents concerning the maximum number of Micro- inverters permitted for installation at each cable section! The Microinverter must be under the module, out of long-term exposure to direct sunlight or rain. -

Note: The serial number of MI-1000 microinverter needs to be placed in the middle of 4 blanks, and it is marked 1, 2, 3 and 4, and the micro-inverse dc port connected to the four pv panels. Step 6. Connect PV Modules a. -
Page 13: Step 7. Energize The System
The recommended installation need keeping the Microinverters underneath the photovoltaic modules, so that the Microinverters can operate in the shade. Direct sunlight may cause damage to the Microinverters. Each module must be connected to the Microinverters with a DC cable having a length of less than 3m. Step 7. -
