2. Safety Instructions
CAUTION
Risk of electric shock from energy stored in the inverter's capacitors.
Do not remove cover until five (5) minutes after disconnecting all sources
of supply have passed, and this can only be done by a service technician.
The warranty may be voided if any unauthorized removal of cover occurs.
CAUTION
The inverter's surface temperature can reach up to 75
risk of burns, do not touch the surface when the inverter is operating.
Inverter must be installed out of the reach of children.
WARNING
The inverter can only accept a PV array as a DC input. Using any other
type of DC source could damage the inverter.
2.3 Notice for use
The inverter has been constructed according to applicable safety and technical guidelines.
Use the inverter in installations that meet the following requirements ONLY:
1). The inverter must be permanently installed.
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 system design must meet inverter specifications.
To start-up the inverter, the Grid Supply Main Switch (AC) must be turned on, BEFORE the DC
Switch is turned on. To stop the inverter, the Grid Supply Main Switch (AC) must be turned off
before the DC Switch is turned off.
2.4 Protection Circuitry and Controls
To meet relevant codes and standards, the Canadian Solar three phase inverter line is
equipped with protective circuitry and controls.
Anti-Islanding Protection:
Islanding is a condition where the inverter continues to produce power even when the grid
is not present. Circuitry, along with firmware, has been designed to determine if the grid is
present by adjusting the output frequency of the inverter. In the case of a 60Hz resonant
system where the inverter is partially isolated from the grid, the inverter programming can
detect if there is a resonant condition or if the grid is actually present. It can also
differentiate between inverters operating in parallel and the grid.

3.1 Environmental considerations
3.1.1 Select a location for the inverter
When selecting a location for the inverter, consider the following:
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.
● The temperature of the inverter heat-sink can reach 75 ℃.
● The inverter is designed to work in an ambient temperature range between -25 to 60 ℃.
● If multiple inverters are installed on site, a minimum clearance of 500 mm should be kept between
each inverter and all other mounted equipment. The bottom of the inverter should be at least 500 mm
above of the ground or floor (see Figure 3.1).
● The LED status indicator lights and the LCD located on the inverter's front panel should not be
blocked.
● Adequate ventilation must be present if the inverter is to be installed in a confined space.
