2.Safety Instructions

2.3 Notice For Use

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.

.6.

CAUTION:

The PV array (Solar panels) supplies a DC voltage when they are exposed to

sunlight.

CAUTION:

Risk of electric shock from energy stored in capacitors of the Inverter. Do not

remove cover for 5 minutes after disconnecting all power sources(service technician

only). Warranty may be voided if the cover is removed without unauthorized .

CAUTION:

The surface temperature of the inverter can reach up to 75℃ (167 F).

To avoid risk of burns, do not touch the surface of the inverter while it’s operating.

Inverter must be installed out of the reach of children.

CAUTION:

Risk of electric shock. Do not remove cover. There is no user serviceable

parts inside. Refer servicing to qualified and accredited service technicians.

PV module used with inverter must have an IEC 61730 Class A rating.

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 single phase inverters feature an

integrated DC switch.

3.3 Keypad

3.4 LCD

There are four keys in the front panel of the Inverter(from left to right):

ESC, UP, DOWN and ENTER keys. The keypad is used for:

Scrolling through the displayed options (the UP and DOWN keys);

Access to modify the adjustable settings (the ESC and ENTER keys).

3. Overview

The two-line Liquid Crystal Display (LCD) is located on the front panel of the Inverter,

which shows the following information:

Inverter operation status and data;

Service messages for operator;

Alarm messages and fault indications.

.8.

Figure 4.1 Recommended Installation locations

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.

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.

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.

When 1 or more inverters are installed in one location, a minimum 12inchs clearance

should be kept between each inverter or other object. The bottom of the inverter should

be 20inchs clearance to the ground.

Visibility of the LED status indicator lights and the LCD located at the front panel of

the inverter should be considered.

Adequate ventilation must be provided if the inverter is to be installed in a confined space.

NOTE:

Nothing should be stored on or placed against the inverter.

Figure 4.2 Inverter Mounting clearance

Install vertically with a maximum incline of +/- 5°.If the mounted inverter is tilted to an

angle greater than the maximum noted, heat dissipation can be inhibited, and may result

in less than expected output power.

4.2 Mounting the Inverter

Please see Figure 4.4 and Figure 4.5 for instruction on mounting the inverter.

Figure 4.3 Inverter wall mounting

The inverter shall be mounted vertically. The steps to mount the inverter are listed below:

Suitable fixing screws

Bracket

1. According to the figure 4.2, 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.

WARNING:

The inverter must be mounted vertically.

4. Lift up the inverter (be careful to avoid body strain), and align the back bracket on the

inverter with the convex section of the mounting bracket. Hang the inverter on the

mounting bracket and make sure the inverter is secure (see Figure 4.5).

4.3 Electrical Connections

4.3.1 Connect PV side of inverter

The electrical connection of the inverter must follow the steps listed below:

1. Switch the Grid Supply Main Switch (AC) OFF.

2. Switch the DC Isolator OFF.

3. Assemble PV input connector to the Inverter.

Before connecting inverter, please make sure the PV array open circuit voltage is

within the limit of the inverter

2.Make sure the bracket is horizontal and the mounting holes (in Figure 4.4 )

are marked correctly. Drill the holes into the wall or pillar at your marks.

3. Use the suitable screws to fix the bracket to the wall.

Before connection, please make sure the polarity of the output voltage of PV array

matches the“DC+”and “DC-”symbols.

Please don’t connect PV array positive or negative pole to the ground, it could

cause serious damages to the inverter.

4. Installation

For all AC connections, 2.5- 6mm 105 ℃ cable is required to be used. Please make sure

the resistance of cable is lower than 1 ohm. If the wire is longer than 20m, it's recommended

to use 6mm cable.
