2. Safety Instructions ~ ~ CanadianSolar
2.4 Protection Circuitry and Controls
To meet relevant codes and standards, the Canadian Solar three phase inverterline is
equipped with protective circuitry and controls. These includeArc Fault Circuit Interrupter
(AFCI) and Anti-Islanding Protection.
Arc Fault Circuit Interrupter AFCI:
Edition 2011 of the National Electrical Code®, Section 690.11, requires that all PV plants
attached to a building are fitted with a means
of detecting and interrupting serial electric
arcs in the PV wiring and array. An electric arcwith a power
of 300W or greatermust be
interrupted bythe AFCI in the time specified by UL
16998. A triggeredAFCI fault may only
be reset manually.
After clearing the source of the fault, theAFCI can be deactivated via
the inverterfront panel interface.
Anti-Islanding Protection:
.10.
Islanding is a condition where the invertercontinues to produce powereven when the grid
is not present. Circuitry, along with firmware, has been designed to determine
if the grid is
present byadjusting the outputfrequency
of the inverter. In the case of a 60Hz resonant
system where the
inverter is partially isolated from the grid, the inverterprogramming 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. Installation
3.1 Environmental considerations
3.1.1 Select a location for the inverter
When selecting a location for the inverter, consider the following:
• The temperature ofthe inverter heat-sink
can reach 167°F(75C).
•
The inverter is designed to work in an ambient temperature range between -13°F to 140°F(-25- 60C).
• Ifmultiple inverters are installed on site, a minimum clearance of20 inches should be kept between
each inverter
and all other mounted equipment. The bottom ofthe inverter should be at least 20
inches above ofthe ground orfloor (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 ifthe inverter is to be installed in a confined space.

WARNING
• Failure to setthe correct grid standard could result in improperoperation
of the inverter, inverter damage or the inverter not operating at all.
• Only certified personnel should
set the grid standard.
• Only
set the grid configuration that is approved by your location and
national grid standards.

5.4 Preliminary checks
WARNING
High Voltage.
AC and DC measurements should be made only by qualified personnel.
5.4.1 DC Connections
Verify DC connections.
1). Lightlytug on each DC cable to ensure it is fully captured in the terminal.
2). Visually check
for any straystrands that may not be inserted in the terminal.
3). Checkto ensure the terminal screws are the correct torque.
5.4.2AC Connections
VerifyAC connections.
1). Lightlytug on each AC cable to ensure it is
fully captured in the terminal.
2). Visually check
for any straystrands that may not be inserted in the terminal.
3). Checkto ensure the terminal screws are the correct torque.
5.4.3 DC configuration
Verify DC configuration.
5.4.3.1 VOC and Polarity
Measure VOC, and checkstring polarity.
5.4.3.1.1 Check string voltage
To measure the open circuit voltage (VOC) and polarity of the individual strings, perform
the following steps:
.28.
WARNING
When the fuse holders are closed, parallel strings on the same MPPT are
connected together.
If there is a voltage difference between the parallel
strings such as different string lengths, current will flow between the
parallel strings. Opening and closing the fuse
holder in this instance is the
same as opening and closing
under load. Damage to equipment and /or
injuryto personnel may occur.
1
). Ensure that all fuse holders are open.
2). Connectthe positive lead
of the meter to the positive string cable of the string under
test. Connectthe negative lead of the meterto the negative string cable of the
string
under test.

5. Commissioning
3). Measure the voltage present between the positive and negative wires of each string.
If the open circuit voltage of the string is nearthe maximum value accepted by the
inverter, verify the string length. Lowambienttemperatures cause an increase in
the string voltage causing potential damage to the inverter.
4). Checkthe polarity
of the string. All digital meters have a negative("-") indicatorthat
indicateswhen a voltage is negative; in this case a string connected in reverse
polarity.
WARNING
Inputvoltages
higher than the maximum value accepted bythe inverter
(see "Specifications" in Section 9) may damage the inverter.
Although Canadian
Solar inverters feature reverse polarity protection,
prolonged connection in reverse polarity may damage these protection
circuits
and/or the inverter.
5.4.3.2 Leakage to ground
Measure leakage to ground.
5.4.3.2.1 Detection
of leakage to ground
Canadian Solar inverters are transformer-less and do not have an array connection to ground.
Any measurement
of a fixed voltage between ground and eitherthe positive or negative string
wiring indicates a leakage (ground fault) to ground and must be corrected priorto energizing
the inverter
or damage to the inverter may result.
To measure leakage to ground, perform the following steps:
1
). Ensure that all fuse holders are open.
2). Ensure that neithernegative norpositive
DC conductors are connected to the ground
strip.
3). Measure each string positive connection to ground.
4). Measure each string negative connection to ground.
5). Verify the voltage is "floating", nota consistent voltage to ground. Make sure you notice
the units
of the measurement. mV is notthe same as V.
6). Do notclose the fuse holder and connectthe strings if a leakage to ground has been
detected. Improperoperation and damage to the inverter may result.
Once all DC tests have been completed, close the fuse holders.
