After mounting M125HV, please open the front cover of the DC wiring box before install the wiring box on the inverter.
Pass through the DC cable from M125HV to DC wiring box, Use 4 M5 hex nut to fix the DC wiring box on the
M125HV inverter. (M5 Nut torque: 3.0 N•m)
* Screw torque: 4.4 N•m
Use M8 hex nut to tighten the cable on terminal.

Below is the procedure for preparing the DC conductors for connection to the DC terminals:
• It is important to choose the proper size for DC cable.
• The cross-sectional area for each DC conductor is 50~300 mm2for Cu. (120~300 mm2for Al)
• The maximum width of each terminal lugs should be within 34 mm, the diameter of screw hole should be
larger than Φ12.5 mm.
• Terminal can use for Cu lug (Tin plated).

Prior to installing conductors on terminal complete the following procedure to make terminals ready for connections.
For each of the DC terminals (PV+ / PV-):
Tighten/Lose nuts with 19 mm socket. If an electric socket is utilized insure the torque setting is low enough to
NOT OVER-TORQUE the screw. Once nut bottoms out, do not turn it any further.
Extreme temperature rise at the clamping point
If the contact resistance between the aluminum conductor and clamping point is toohigh, the
clamping point can become very hot and even catch fire in extreme cases.
To ensure a safe and reliable contact, always perform the following work steps:
Please select the Al wire size according to rules due to lower conductivity of Al.
Keep the installation location as free as possible from moisture or corrosive atmospheres.
Connect the aluminum cables quickly.
Tighten the clamping screw in the clamping body with the maximum permissible tightening torque.
NOTICE
The figure above illustrates the location of the DC conduit entry and connections to the DC terminal block:
- Ensure the correct conductor is connected to the appropriate terminal.
- After conductor is inserted, use M12 nuts to tight PV+/PV- terminal with a torque of 45 N•m.
DANGER : ELECTRICAL HAZARD!!
- PV array converts sunlight into electric power with high DC voltage and high DC current which can cause
dangerous electrical shock hazard!
- Use an opaque material to cover the PV array before wiring or cabling.
- Ensure the correct polarities are connected when DC cabling is applied.
DANGER!
- It is forbidden to open both doors at the same time.
WARNING !
- The risk of electric shock and fire exists because of high DC and AC voltages.
- Only PV modules that are listed with system voltage under 1600V are permitted for use.
- Inverter warranty void if the DC input voltage exceeds 1600 Vdc.
- Ensure the DC switch is placed in the "OFF" position, and the PV array is disconnected when doing DC cabling.
CAUTION: DC SWITCH ON/OFF !
- In order not to damage the components in the inverter, don’t repeat to change the status of DC Switch quickly,
the correct operation is waiting for the LED display show "green off and yellow flash" (No DC) or turn on the
switch after 5 minutes later.
CAUTION: WRONG AC WIRING !
- In order not to damage the components in the inverter, ensure the correct conductor is connected to the
appropriate DC terminal on the inverter.
- Ensure the DC conductors used are sized to the correct ampacity per NEC or other local code.

* It is recommended to apply electrical grease before fitting wire conductor into terminal lug for best protection.
The working temperature of power cable should be at least 90°C.

請遵循以下步驟組裝直流端子：
‧ 請選用適當線材尺寸
‧ 線材表面積範圍: 銅線- 50~300 mm2 / 鋁線- 120~300 mm2
‧ 每個壓接端子的最大寬度需小於34 mm，內徑需大於 Φ12.5 mm
‧ 可以使用銅端子
* 將導線插入端子接線片之前，建議塗抹凡士林 ( 須為中性、不含酸、鹼成分 )，以獲得最佳保護。
選用的纜線操作溫度要有到 90°C

在進行導線與端子座安裝連接之前，請遵循以下步驟。
對於每個直流端子（PV+ / PV-）：
請用19mm六角板手進行拆裝螺帽。如果使用電動工具進行施工，請確保使用適當扭力值，避免超過或不足擰緊螺帽的
扭力值。當直流鎖附螺帽頂到最低點時，請勿再進行鎖附，避免造成端子座損傷。
有可能產生高溫:
若壓接點的阻抗過高，該點則有可能產生高溫導致火災。
為確保安全性及可靠的接觸點，請確實遵守以下步驟
鋁線的導電性較銅線差，鋁線線徑請至少選用比銅線線徑大一個等級。
安裝鋁線時請盡量在低濕度且低腐蝕性的環境下進行。
安裝過程需快速。
使用最大允許的壓接扭力進行壓接。
注意
上圖為直流導管安裝處和連接機器直流端子的位置圖：
- 卸下所有直流端子上的六角螺帽
- 確保將正確的導線連接到相應的端子位置
- 插入導線後，使用M12螺母鎖緊PV+/PV-端子，安裝鎖附扭力值為45 N‧m
危險:觸電危險!!
- 太陽能串列將太陽能轉換成高壓直流形式，此高壓有可能造成觸電危險。
- 配線前請使用非透明物質將太陽能串列遮蓋起來。
- 配線時請確認電壓極性
危險 !
- 禁止同時開啟兩側前蓋。
警告!
- 直流及交流高電壓，存在觸電及火災危險。
- 僅允許使用有標示低於1600V的太陽能串列。
- 直流電壓超過1600V則保固失效。
- 配線時請確認直流開關在"關"的模式，且太陽能陣列沒有連接。
注意：直流開關！
- 為了不損壞變流器內部元件，請勿頻繁且快速地切換直流開關，
正確的操作方式為等待LED顯示"綠燈滅及黃燈閃爍"(無直流) 或間隔5分鐘。
注意：錯誤的直流線材！
- 為了不損壞變流器中的組件，請確保將正確的線材連接到變流器上相應的直流端子。
- 確保所使用的直流導體尺寸符合NEC或當地電力法規的規範。
