instructions, which if not correctly followed, could result in electric shock.
CAUTION:
CAUTION, HOT SURFACE symbol indicates safety instructions, which if not
correctly followed, could result in burns.
NOTE:
NOTE symbol indicates important safety instructions, which if not correctly
followed, could result in some damage or the destruction of the inverter.
WARNING:
WARNING symbol indicates important safety instructions, which if not
correctly followed, could result in serious injury or death.
WARNING:
Electrical installations must be done in accordance with the local and national
electrical safety standards.
WARNING:
Please don’t connect PV array positive(+) or negative(-) to ground, it could
cause serious damage to the inverter.
CAUTION:
The PV array (Solar panels) supplies a DC voltage when they are exposed to
sunlight.
WARNING:
To reduce the risk of fire, over-current protective devices (OCPD) are
required for circuits connected to the Inverter.
The DC OCPD shall be installed per local requirements. All photovoltaic
source and output circuit conductors shall have disconnects that comply
with the NEC Article 690, Part II. All Canadian Solar three phase inverters
feature an integrated DC switch.
CAUTION:
Risk of electric shock. Do not remove cover. There is no user serviceable
parts inside. Refer servicing to qualified and accredited service technicians.
The inverter has been constructed according to the applicable safety and technical
guidelines. Use the inverter in installations that meet the following specifications only:
1. Permanent installation is required.
2. The electrical installation must meet all the applicable regulations and standards.
3. The inverter must be installed according to the instructions stated in this manual.
4. The inverter must be installed according to the correct technical specifications.
5. To startup the inverter, the Grid Supply Main Switch (AC) must be switched on, before
the solar panel's DC isolator shall be switched on. To stop the inverter, the Grid Supply
Main Switch (AC) must be switched off before the solar panel's DC isolator shall be
switched off.

If the inverter is not to be installed immediately, storage instructions and environmental
conditions are below:
Use the original box to repackage the inverter, seal with adhesive tape with the
desiccant inside the box.
Store the inverter(s) in a clean and dry place, free of dust and dirt.
Keep box(es) away from corrosive materials to avoid damage to the inverter enclosure.
Inspect packaging regularly. If packaging is damaged(wet, pest damage, etc),
repackage the inverter immediately.
Store the inverter(s) on a flat, hard surface - not inclined or upside down.
After long-term storage, the inverter needs to be fully examined and tested by qualified
service or technical personnel before using.
Restarting after a long period of non-use requires the equipment to be inspected
and, in some cases, the removal of oxidation and dust that has settled inside the
equipment will be required.
To select a location for the inverter, the following criteria should be considered:
Do not install in small closed spaces where air cannot circulate freely. To avoid
overheating, always make sure the flow of air around the inverter is not blocked.
Exposure to direct sunlight will increase the operational temperature of the inverter and
may cause output power limiting. Canadian Solar recommends inverter installed to avoid
direct sunlight or raining.
To avoid over heating ambient air temperature must be considered when choosing the
inverter installation location. Canadian Solar recommends using a sun shade minimizing
direct sunlight when the ambient air temperature around the unit exceeds 104°F/40°C.
5.1 Select a Location for the Inverter
Figure 5.1 Recommended Installation locations
WARNING: Risk of fire
Despite careful construction, electrical devices can cause fires.
Do not install the inverter in areas containing highly flammable materials or
gases.
Do not install the inverter in potentially explosive atmospheres.
NOTE:
Nothing should be stored on or placed against the inverter.

.11..10.
The visibility of LED status indicator lights and LCD should be considered.
Install vertically (+/- 5°) or tilted backward (<=15°).
Don't mount inverter on the tilted forward wall.
Don't mount inverter on the horizontal.
5.2 Mounting the Inverter
Dimensions of mounting bracket:

Canadian Solar recommends 2 ground protection methods: Through grid terminal connection
and external heat sink connection.
If AC terminal is used to connect ground, please refer to the contents of 5.3.3.
If the heat sink is used to connect the ground, please follow the steps below:
1) Prepare the grounding cable: recommend to use the ≥ 6mm² outdoor
copper-core cable.
Important:
3) Strip the ground cable insulation to a suitable length(see Figure 5.8).
Figure 5.8 suitable length
Important:
4) Insert the stripped wire into the OT terminal crimping area and use the hydraulic
clamp to crimp the terminal to the wire (see Figure 5.9).
Figure 5.9 strip wire
Important:
For multiple inverters in parallel , all inverters should be connected to the
same ground point to eliminate the possibility of a voltage potential existing
between inverter grounds.
B (insulation stripping length) is 2mm~3mm longer than A (OT cable
terminal crimping area) 2mm~3mm.
After crimping the terminal to the wire, inspect the connection to ensure the
terminal is solidly crimped to the wire.
5) Remove the screw from the heat sink ground point.

For improving anti-corrosion performance,
after ground cable installed, apply silicone or paint is preferred to protect.

5. Measure PV voltage of DC input with multimeter, verify DC input cable polar
(see figure 5.17), and ensure each string of PV voltage in range of inverter operation.
Connect DC connector with inverter until hearing a slight clicking sound indicates
connection succeed. (see figure 5.18)
5.3.2 Connect PV side of inverter
Caution:
If DC inputs are accidently reversely connected or inverter is faulty or not
working properly, it is NOT allowed to turn off the DC switch as it will damage
the inverter and even leads to a fire disaster.
The correct actions are:
*Use a clip-on ammeter to measure the DC string current.
*If it is above 0.5A, please wait for the solar irradiance reduces until the
current decreases to below 0.5A.
*Only after the current is below 0.5A, you are allowed to turn off the DC
switches and disconnect the PV strings.
Please note that any damages due to wrong operations are not covered in
the device warranty.

applications and requirements.
The inverter has intergrated export limitation functionality.
To use this function, a power meter must be installed, it should be installed in the load side
or in the grid side, see Figure 5.26 and Figure 5.27. After the inverter power on, please set
the corresponding configuration as sections 7.5.11.1.2 and 7.5.11.1.3.

6. Start & Stop
6.1 Start the Inverter
To start up the Inverter, it is important that the following steps are strictly followed:
1. Switch the grid supply main Switch (AC) ON first.
2. Switch the DC switch ON. If the voltage of PV arrays are higher than start up voltage,
the inverter will turn on. The red LED power will light.
3. When both the DC and the AC sides supply to the inverter, it will be ready to generate
power. Initially, the inverter will check both its internal parameters and the parameters
of the AC grid, to ensure that they are within the acceptable limits. At the same time,
the green LED will flash and the LCD displays the information of INITIALIZING.
4. After 30-300 seconds (depending on local requirement), the inverter will start to
generate power. The green LED will be on continually and the LCD displays
GENERATING.
WARNING:
Do not touch the surface when the inverter is operating. It may be
hot and cause burns.
6.2 Stop the Inverter
To stop the Inverter, the following steps must be strictly followed:
1. Turn off the ac switch.
2. Put the DC SWITCH on the inverter in the position of "OFF".
3. Remove the positive and negative dc lines and remove the ac lines.
5. Installation
