3.2 LED Status Indicator Lights
There are three LED status indicator lights on the front panel of the inverter.
On the Left: POWER LED indicates the power status of the inverter.
On the Middle: OPERATION LED (green) indicates the operation status.
On the Right: ALARM LED (yellow) indicates the alarm status.
Please see Table 3.1 for details
2. The inverter must be connected to a separate grounded AC group, to which no
other electrical equipment is connected
3. The electrical installation must meet all the applicable regulations and standards.
4. The inverter must be installed according to the instructions stated in this
manual.
5. The inverter must be installed according to the correct technical specifications.
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.

1. The red marks below indicate perforations used to form handles for carrying the carton
with the inverter. The inverter requires 2 people to lift and carry.
Figure 4.1 move the inverter
2.Two people are required to remove the inverter from the carton.
Handles are formed into the heatsink for ease of handling the i nverter. See figure 4.2 below.

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.

5. Use supplied screws to secure the bottom of the inverter to the mount bracket.
5.3 Electrical Connections
The electrical connection of the inverter must follow the steps listed below:
1. Switch the Grid Supply Main Switch (AC) OFF. Switch the DC Switch OFF.
2. Connect the inverter to PV array.
3. Connect the inverter to the grid.
The Inverter is designed with quick-connect terminal port for electrical connection
without removing the cover. The meanings of the symbols at the bottom of the inverter
are listed in Table 5.1. All electrical installations must be in accordance with all local
and national standards.
