instructions and safety notices listed in installation document.
4.10.2 Installation item in PV system
The structure of PV direct-driven inverter multi VRF system is shown in the following fig,
PV system installation mainly includes installation for PV frame and PV battery component，
auxiliary cable pavement and installation for distribution equipment.
4.10.2.1 Installation of PV component frame
PV component frame shall be installed on site after acceptance of Party A and the
professional supervising unit. The engineered frame is aluminum alloy or hot galvanized steel.
During construction, try to avoid scratching the surface of aluminum alloy or the spiculate
objects in galvanized layer.
Installation shall be carried out in order. Separate the connector (to connect with roof
slabs), main keel and sub keel (if needed), then conduct lifting uniformly. Calculate correct
material quantity in each row according to the PV component quantity in each row, including the
amount of related accessory, e.g. bolt. Firstly, fix the connector on the roof slab near the upright
lock; secondly, fix corresponding main keel and sub keel (if sub keel is needed), then fix and
connect the bolts of each component together. Tighten the bolt manually first, then fasten it with
manual wrench or electrical wrench, meanwhile, observe and adjust its straightness with nylon
wire.
After installation is completed, clean up the packing material on site.
