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, regardless if they are connected or not to an inverter.
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 the frontal cover of the inverter.
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 start up the inverter, please make sure the Grid Supply Main Switch (AC) is switched on,

5. Installation
4. Product handing and storage
Storage temperature must be between -40℃ and 70℃ and the humidity should be
between 0 and 100% non-condensing.
Stack no more than three (3) inverters high.
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:

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 rain.
To Avoid overheating, 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.
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 environment.
NOTE:
Nothing should be stored on or placed against the inverter.

Please install the inverter vertically. If the inverter cannot be mounted vertically, it may
be tilted backward to 15 degrees from vertical.
When multiple inverters are installed on site, a minimum clearance of 500mm,should be kept
between each inverter and any other mounted equipment. The bottom of the inverter must
be at least 500mm from the ground or floor. See figure 5.2.

Canadian Solar requires 2 ground protection methods: through grid terminal connection
and external heat sink connection.
When connecting the AC terminal grounding cable, please refer to the contents of 5.3.3.
When connecting the heat sink grounding cable, please follow the steps below:
1. Prepare the grounding cable: it is recommended to use a cable with cross-section of 16mm²
or higher with outdoor rating.
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.

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 it may even lead to a fire.
The correct actions are:
· Use a clip-on ammeter to measure the DC string current.
· if the current is higher than 0.5A, please wait until the solar irradiance
decreases, so that the current value is below 0.5A.
· only when the current is below 0.5 A, it is allowed to switch off the DC
switches and afterwards disconnect the PV strings.
Please note that any damages due to wrong operations are not covered by
the warranty.

5.3.6 Logic interface connection (Only for UK)
Logic interface is required by G98 and G99 standard that can be operated by a simple switch
or contactor. When the switch is closed the inverter can operated normally. When the switch
is opened, the inverter will reduce it’s output power to zero within 5s.
Pin5 and Pin6 of RJ45 terminal is used for the logic interface connection.
Please follow below steps to assemble RJ45 connector.
1. Insert the network cable into the communication connection terminal of RJ45.
(As shown in figure 5.30)
Figure 5.30 RJ45 communication connection terminals
2. Use the network wire stripper to strip the insulation layer of the communication cable.
According to the standard line sequence of figure 5.31 connect the wire to the plug of
RJ45, and then use a network cable crimping tool to make it tight.
Correspondence between the cables
and the contacts of plug, Pin5 and Pin6

7.2 Information
6.1 Start the Inverter
To start 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 initialize. 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"
(See page 17 for the special note).

7. Operation
Canadian Solar Three Phase Inverter does not require any regular maintenance. However,
cleaning the dust on heat-sink will help the inverter to dissipate the heat and increase its life
time. The dust can be removed with a soft brush.
CAUTION:
Do not touch the inverter's surface when it is operating. Some parts of the
inverter may be hot and cause burns. Turn off the inverter (refer to Section
6.2) and wait for a cool-down period before before any maintenance or
cleaning operation.
The LCD and the LED status indicator lights can be cleaned with a damp cloth if they are too
dirty to be read.
NOTE:
Never use any solvents, abrasives or corrosive materials to clean the inverter.
8. Maintenance
The inverter is designed in accordance with the most important international grid-tied
standards and safety and electromagnetic compatibility requirements. Before delivering to
the customer, the inverter has been subjected to several tests to ensure its optimal operation
and reliability.
In case of failure, the LCD screen will display an alarm message. In this case, the inverter
may stop feeding into the grid. The failure descriptions and their corresponding alarm
messages are listed in Table 9.1:
