2.3 Notice For Use
WARNING:
To reduce the risk of fire, over-current protective devices (OCPD) are required
for circuits connected to the Inverter. The recommended rated trip current of
OCPD, CSI-20KTL-GI-FL should be 40A, CSI-25KTL-GI-FL,CSI-30KTL-GI-FL,
CSI-33KTL-GI-FL and CSI-40KTL-GI-HFL should be 63A.
CAUTION:
Risk of electric shock. Do not remove cover. Refer maintenance servicing to
qualified and accredited service technician.
CAUTION:
The PV array (Solar panels) supplies a DC voltage when it is exposed to light.
CAUTION:
Risk of electric shock from energy stored in capacitors of the Inverter. Do not
remove cover until 5 minutes after disconnecting all sources of supply. Service
technician only. Warranty may be voided if any unauthorized removal of cover.
CAUTION:
The surface temperature of the inverter can exceed 75℃ (167F).
To avoid risk of burns, DO NOT touch the surface when inverter is operating.
The inverter must be installed out of reach of children.
1. Secure inverter installation is required.
6. To startup the inverter, the Grid Supply Main Switch (AC) must be switched on, before
the solar panel's DC isolator switched on. To stop the inverter, the Grid Supply Main
Switch (AC) must be switched off before the solar panel's DC isolator switched off.
7. DC input voltage of inverter must less than its maximum input voltage of inverter.

5.2 Mounting the Inverter
The inverter can be mounted to the wall or metal strut of module. The mounting holes
should be consistent with the size of the bracket or the dimensions shows below.
1. According to the figure 5.2, select the mounting height of the bracket and mark the
mounting holes. For brick walls, the position of the holes should be suitable for the
expansion bolts.
2.MAKE SURE the bracket is horizontal and the mounting holes A, B, and C (in
Figure 5.3) are in the correct points. Drilling the holes on the wall according
the marks.
WARNING:
The inverter must be mounted vertically on a vertical wall.
Use suitable expansion screws of bolts to attach the bracket
To the wall of rack as shown in figure 5.4.
The inverter should be mounted in a vertical position. The steps of mounting are as follows:
Figure 5.3 The dimensions of the mounting bracket (in mm)
3. Using the expansion bolts to fix the bracket to the wall.
Install on a vertical surface or structure capable of bearing the weight.
Must install vertically within +/- 5. If the inverter is tilted from the vertical plane heat
dissipation can be inhibited. This may reduce system performance or reduce service
life of the inverter.
Visibility of the LED status indicator lights and LCD display screen should be considered.
NOTE:
The inverter must be installed out of reach of children.
A minimum of 500mm clearance is required top, bottom, left and right of the inverter
(isolator enclosures excepted) for air flow and cooling.

6.2 Stop the inverter
1. Switch the Supply Main Switch (AC) OFF.
2. Wait 30 seconds. Switch the DC switch OFF or directly disconnect the DC output connector.
The LEDs and LCD of the inverter will be off within one minute.
6.1 Start the inverter
1. Switch the Supply Main Switch (AC) ON first.
2. Turn on the DC switch of PV array. If the voltage of PV array is higher than the start up
voltage, the inverter will turn on, and the initial interface of LCD will show “Current status:
Waiting” on the upper left corner.
3.When both the AC and DC are supplied ot the inverter, it will be ready to generate power.
Initially, the inverter will check internal and AC parameters to ensure they are within
acceptable limits. At the same time, the green LED will flash and the LCD displays
INITIALIZING.
4. After around 30-180 second (based on local requirement), the inverter will start to generate
power. The green LED will be on continually and the LCD displays “Current status:
Generating.”
Current status: Waiting
Current status: Generating
NOTE:
If the DC input switch is ON before grid breaker, inverter may show fault message
“No_Grid” on current status, the fault will clear when grid voltage is normal.
