Huawei SUN2000-3KTL-M1 Series User Manual

WARNING
Before inserting the positive and negative connectors into the positive and
negative DC input terminals of the SUN2000, ensure that the DC switch is set to
OFF.
CA UTION
Use the positive and negative Staubli MC4 metal terminals and DC connectors
supplied with the SUN2000. Using incompatible positive and negative metal
terminals and DC connectors may result in serious consequences. The caused
device damage is not covered under warranty.
NO TICE
● Cables with high rigidity, such as armored cables, are not recommended as DC
input power cables, because poor contact may be caused by the bending of the
cables.
● Before assembling DC connectors, label the cable polarities correctly to ensure
correct cable connections.
● After crimping the positive and negative metal terminals, pull back the DC
input power cables to ensure that they are securely connected.
● Insert the crimped metal terminals of the positive and negative power cables
into the appropriate positive and negative connectors. Then pull back the DC
input power cables to ensure that they are connected securely.
● If a DC input power cable is reversely connected and the DC switch is turned
on, do not operate on the DC switch or the positive/negative connectors
immediately. Otherwise, the device may be damaged. The caused device
damage is not covered under any warranty. Wait until the solar irradiance
declines at night and the PV string current reduces to below 0.5 A, and then
turn o the DC switch and remove the positive and negative connectors.
Correct the PV string polarity before reconnecting the PV string to the
SUN2000.
● During DC input power cabling, leave at least 50 mm of slack. The axial tension
on PV connectors must not exceed 80 N. Radial stress or torque must not be
generated on PV connectors.
NO TE
● The DC voltage measurement range of the multimeter must be at least 1100 V.
● If the voltage is a negative value, the DC input polarity is incorrect. Correct the polarity.
● If the voltage is greater than 1100 V DC, too many PV modules congured to the same
string. Remove some PV modules.
● If the PV string is congured with an optimizer, check the cable polarity by referring to
the smart PV optimizer quick guide.
