2. Safety warnings and instruc�ons

2.1 Safety signs

2.2 Safety instruc�ons

Improper use may result in poten�al electric shock hazards or burns. This manual contains

important instruc�ons that should be followed during installa�on and maintenance. Please

read these instruc�ons carefully before use and keep them for future reference.

Safety symbols used in this manual, which highlight poten�al safety risks and important safety

informa�on, are listed as follows:

Shock Hazard:

Cau�on, risk of electric shock symbol indicates important safety instruc�ons,

which if not correctly followed, could result in electric shock.

High Temperature Hazard:

Cau�on, hot surface symbol indicates safety instruc�ons, which if not correctly

followed, could result in burns.

Safety Hint:

Note symbol indicates important safety instruc�ons, which if not correctly

followed, could result in some damage or the destruc�on of the inverter.

Warning:

Warning symbol indicates important safety instruc�ons, which if not correctly

followed, could result in serious injury or death.

Shock Hazard:

Prohibit disassembling inverter case, there exis�ng shock hazard, which may

cause serious injury or death, please ask qualiﬁed person to repair.

Warning:

Electrical installa�on of the inverter must conform to the safety opera�on rules

of the country or local area.

Warning:

Inverter adopts non-isolated topology structure, hence must insure DC input and

AC output are electrical isolated before opera�ng the inverter.

Strictly prohibit grounding the posi�ve and nega�ve poles of the PV string.

Otherwise it will damage the inverter.

4.1 Select installa�on loca�on

4. Product installa�on

To select a loca�on for the inverter, the following criteria should be considered:

WARNING: Risk of ﬁre

● Do not install the inverter in areas containing highly ﬂammable materials or gases.

● Do not install the inverter in poten�ally explosive atmospheres.

● Do not install in small closed spaces where air can not circulate freely. To avoid overhea�ng,

always make sure the ﬂow of air around the inverter is not blocked.

● Exposure to direct sunlight will increase the opera�onal temperature of the inverter and

may cause output power limi�ng. It is recommended that inverter installed to avoid direct

sunlight or raining.

● To avoid overhea�ng ambient air temperature must be considered when choosing the

inverter installa�on loca�on. It is recommended that using a sun shade minimizing direct

sunlight when the ambient air temperature around the unit exceeds 100°F/40℃.

Pic 4.1 Recommended installa�on place

- 08 -

● Install on a wall or strong structure capable of bearing the weight.

● Install ver�cally with a maximum incline of +/-15°. If the mounted inverter is �lted to an

angle greater than the maximum noted, heat dissipa�on can be inhibited, and may result in

less than expected output power.

● If install more than one inverter, must leave at least 500mm gap between each inverter. And

each inverter must be at least 500mm above and below.And must install the inverter at the

place where children cannot touch. Please see picture 4.3.

● Consider whether the installa�on environment is helpful to see the inverter LCD display and

indicator status clearly.

● Must oﬀer a ven�late environment if inverter installed in the air�ght house.

Safety Hint:

2. Ensure that the posi�on of the installa�on holes on the wall is in accordance with the

moun�ng plate, and the moun�ng rack is horizontally placed.

3. Hang the inverter to the top of the moun�ng rack and then use the M4 screw in the

accessory to lock inverter heat sink to the hanging plate, to ensure that the inverter will not

move.

Procedure shows below:

1. Locate on the appropriate wall according to the bolt posi�on on the moun�ng bracket, then

mark the hole.On the brick wall, the installa�on must be suitable for the expansion bolt

installa�on.

1. Switch the Grid Supply Main Switch(AC)OFF.

2. Switch the DC lsolator OFF.

3. Assemble PV input connector to the inverter.

Safety Hint:

Please don’t connect PV array posi�ve or nega�ve pole to the ground, it could

cause serious damages to the inverter.

Safety Hint:

Before connec�ng inverter, please make sure the PV array open circuit voltage is

within the 1000V of the inverter.

Safety Hint:

Before connec�on, please make sure the polarity of the output voltage of PV

array matches the “DC+” and “DC-” symbols.

Safety Hint:

Please use approved DC cable for PV system.

The AC output connector is divided into three parts: matching socket, sleeve and sealing-

sleeve, as shown in picture 5.7, the steps are as follows:

Step 1: Remove the cable sealing ring and sleeve in sequence from the AC connector.

Step 2: Use strippers to strip the protec�ve sheath and insula�on layer of the AC cable to the

right length, as shown in Picture 5.8.

Step 3: Insert the cable (L1, L2, L3, N PE) into the sealing sleeve.，

Step 4: Use the hexagon screwdriver, loosen the bolts of the socket in turn, and insert each

cable core into the corresponding jack, and set each screw. The connec�on hole of AC

connec�on terminal labeling is shown in Picture 5.9.

Warning:

Be careful to dis�nguish the L1, L2,L3,N and PE of the AC cables.

5.3 The connec�on of the ground line

Good grounding is good for resis�ng surge voltage shock and improving EMI perfor-

mance.Therefore, before connec�ng AC, DC and communica�on cables, you need to ground

the cable ﬁrstly. For a single system, just ground the PE cable. For mul�ple machine systems,

all PE cables of the inverter need to be connected to the same grounding copper platoon to

ensure the equipoten�al connec�on. The installa�on of the shell ground wire is shown as

picture 5.11.

Warning:

Inverter has built-in leakage current detec�on circuit, If an external leakage

current protec�on device is connected, its opera�ng current must be greater

than 300 mA or higher, otherwise inverter may not work properly.

5.4 Max. over current protec�on device

In order to protect the inverter AC connec�on, it is recommended to install a circuit breaker to

prevent overcurrent. See table 5.3 below.

Table 5.3 Recommended current protector speciﬁca�ons

5.5 Inverter monitoring connec�on

Inverter has the func�on of wireless remote monitoring. The inverter with Wi-Fi func�on is

equipped with Wi-Fi Plug to connect the inverter and network. Wi-Fi Plug's opera�on,
