1.2 General Safety

IMPORTANT SAFETY INSTRUCTIONS : SAVE THESE INSTRUCTIONS !

- Please read these instructions carefully and save them for later use.

To prevent personal injury and/or property damage, and also to ensure long
term operation of the solar inverter, it is imperative this section be read carefully
and all the safety instructions understood 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, certifications, and standards but precautions
must be observed when installing and operating the product.
This product is suitable for both indoor and outdoor use.

ATTENTION : NO GALVANIC ISOLATION

- The design of this inverter is transformerless. There is no isolation transformer

between the AC and DC sides, i.e., the product does not require galvanic isolation.
In order to function properly, any PV array connected must have its PV circuits
isolated from ground, i.e., do not bond either side of the array to ground!
If a grounded PV array is connected to the inverter, the error message INSULATION
(E34) will appear on the display.
- It is prohibited to reference the L1, L2, L3 or N terminal to ground; to do so will
damage the inverter and void the producr warranty.

1.2.1 Condition of Use

- M100_210 is a transformerless solar inverter with 1 MPP tracking input, which
converts the variable direct current generated by the solar array into a utility
frequency grid-compliant balanced three-phase AC current and feeds it into
the utility grid.
- The Photovoltaic modules used must be compatible with the inverter. PV
modules with a high parasitic capacitance to ground may only be utilized if the
capacitive coupling does not exceed 10μF.
- The inverter should be operated in countries which are approved by DELTA
and the grid operator.

3.7.1 RS-485 Connection

The pin definition for the RS-485 terminal block is shown in Table 3-3.
- Pins 1 and 2 provide a 12VDC / 0.5A bus for use with accessories.
- Pins 3 and 5 are both connected to the DATA+ input.
- Pins 4 and 6 are both connected to the DATA - input.
These connections allow easy daisy-chaining of multiple inverters.
A 120ohm bus termination resistor and associated control switch are located
on the communication board (Table 3-4).
Different RS-485 connection scenarios require different set up for the 120ohm
bus termination resistor.
• When several inverters are cascaded (i.e., "daisy-chained") only the last inverter
in the chain must have its bus termination resistor switched ON (Figure 3-25).
• If the length of any RS-485 bus is greater than 610m, the use of Belden 3105A
cable (or eq.) is recommended to insure communication quality.

ATTENTION
- In order to have good transfer quality, twisted-pair wire is recommended to be
used as communication cable.

為確保變流器以較高效能運作，請參考下列模組組串配置建議：
1. 直流輸入電壓應大於交流線電壓*1.5倍（或交流相電壓*2.5倍）
若直流輸入電壓低於上述值，則變流器將無法正常運轉。
例如:交流電壓 = 400Vac, 直流輸入電壓需> 400Vac*1.5 = 600Vdc
2. 模組組串設計應考慮環境最低溫度，以確保模組組串的開路電壓低於1000Vdc
3. 當組串開路電壓高於1100Vdc時，變流器有損壞的風險且會導致產品保固失效
