General Safety; Condition Of Use - Delta M88 Series Operation And Installation Manual

1.2 General Safety

IMPORTANT SAFETY INSTRUCTIONS : SAVE THESE INSTRUCTIONS !
- Please read these instructions carefully and save them for later use.
To prevent any personal injury and any property damage, also ensure long-term
operation of the solar inverter, you must read this section carefully and review all
the safety instructions at all times before using this inverter.
This user manual provides important instructions for Delta grid-tie transformerless
solar inverter. The product is designed, tested, verified, and certified according
to international safety requirements, regulations, and standards but precautions
must be observed when installing and operating the product.
ATTENTION : NO GALVANIC ISOLATION
- There is no accessory such as a transformer along with our product and
therefore the product has no galvanic isolation.
External transformer should be installed between AC output of inverter and Grid.
Please do not connect grounded Photovoltaic modules to the product.
If you connect grounded Photovoltaic modules to the product, the error message
INSULATION (E34) shows up.
- It is prohibited to connect the L1, L2, L3, and N to the ground.

1.2.1 Condition of Use

The M88H is a transformerless solar inverter with two MPP trackers which
converts the variable direct current of the solar array into a utility frequency
grid-compliant three-phase current and feeds it into the utility grid.
The Photovoltaic modules used must be compatible with the inverter.
Photovoltaic modules with a high parasitic capacitance to ground may only be
applied if the capacitive coupling does not exceed 8μF.
The inverter must only be operated in countries for which it is approved by Delta
and the grid operator.
