74 Installation checklist
Mechanical installation (see
Check that:
The mechanical installation and markings correspond to the system's layout and design
drawings.
The installation location is properly selected.
There is sufficient free space around the unit (see
The cooling air is able to flow freely (see
The ambient operating conditions are allowed (see
on page 115).
The inverter is properly fastened to the installation base and secured to mounting plate.
There are no tools, foreign objects or dust from drilling outside or inside of the inverter.
The type labels or the inverters are intact and visible for the user.
The PVS300 user's guide is situated at the inverter where users can find it.
Electrical installation (see
Check that:
The electrical installation and markings correspond to the system's wiring diagrams.
The electrical installation and markings correspond to the AC distribution board wiring
diagrams.
The electrical ratings of solar array and other system components are compatible with
inverter.
The solar array and string voltages are not exceeding the nominal input voltage of the
inverter.
The AC line (grid) voltage matches the nominal output voltage (230 V AC) of the inverter.
The DC power cable connections at DC+ and DC- connectors and their locking are OK.
Unused DC input connectors have sealing caps on.
The DC string fuses have adequate nominal ratings (see
requirements on page 113).
There are string fuses inserted in every input of the inverter.
The insulation of the assembly is sufficient. See
on page 58.
The inverter has a proper connection to Protective Earth. See
page 14.
The AC power cable connections at L, N and PE and their tightening torques are OK. See
AC cabling connection procedure
The power cables are routed separately from other cables. See
page 58.
The external control connections to the inverter are OK. See
cables on page 66.
