● Ensure that the PE cable is securely connected. Otherwise, electric shocks may occur.

● Do not connect the neutral wire to the enclosure as a PE cable. Otherwise, electric shocks may occur.

● The PE point at the AC output port is used only as a PE equipotential point, and cannot substitute for the PE point on the enclosure.

● It is recommended that silicone grease or paint be used around the ground terminal after the PE cable is connected.

Additional Information

The inverter provides the grounding detection function. This function is used to check whether the inverter is properly grounded before the inverter starts, or check whether the inverter ground cable is disconnected when the inverter is running. This function is used to check whether the inverter is properly grounded under limited conditions. To ensure the safe operation of the inverter, properly ground the inverter according to the connection requirements of the PE cable. For some power grid types, if the output side of the inverter is connected to an isolation transformer, ensure that the inverter is properly grounded and then disable Grounding abnormal shutdown so that the inverter can run properly.

● According to IEC 62109, to ensure the safe operation of the inverter in the case of PE cable damage or disconnection, properly connect the PE cable of the inverter and ensure that it meets at least one of the following requirements before the grounding detection function becomes invalid.

Page 42

NO TICE

SUN2000-(12KTL-25KTL)-M5 Series User Manual 5 Electrical Connections

– If the PE terminal of the AC connector is not connected, the PE cable on

the enclosure must be a single-core outdoor copper cable with a crosssectional area of at least 10 mm2.

– Use cables with the same diameter as the AC output power cable and

ground the PE terminal on the AC connector and the ground screws on the enclosure.

● In some countries and regions, the inverter must have additional ground cables. In this case, use cables with the same diameter as the AC output power cable and ground the PE terminal on the AC connector and the ground screws on the enclosure.

Procedure

Step 1 Crimp an OT terminal.

● Avoid scratching the core wire when stripping a cable.

● The cavity formed after the conductor crimp strip of the OT terminal is crimped

must wrap the core wires completely. The core wires must contact the OT terminal closely.

● Wrap the wire crimping area with heat-shrink tubing or insulation tape. The

heat-shrink tubing is used as an example.

● Use a heat gun carefully to avoid heat damage to the equipment.

5.4 Installing DC Input Power Cables

Precautions

● Before connecting the DC input power cable, ensure that the DC voltage is

within the safe range (lower than 60 V DC) and that the inverter DC SWITCH is OFF. Failing to do so may result in electric shocks.

● When the inverter is operating, it is not allowed to work on the DC input power

cables, such as connecting or disconnecting a PV string or a PV module in a PV string. Otherwise, electric shocks may occur.

● If no PV string connects to a DC input terminal of the inverter, do not remove

the watertight cap from the DC input terminals. Otherwise, the protection level of the inverter will be

aected.

WARNING

NO TICE

SUN2000-(12KTL-25KTL)-M5 Series User Manual 5 Electrical Connections

Ensure that the following conditions are met. Otherwise, the inverter may be damaged, or even a re may occur.

● PV modules connected in series in each PV string are of the same specications.

● The maximum open-circuit voltage of each PV string must be less than or

equal to 1100 V DC.

● The maximum short-circuit current of each PV string must be less than or equal

to 20 A.

● PV strings must be connected in the correct polarity. The positive and negative

terminals of a PV string connect to the corresponding positive and negative DC input terminals of the inverter, respectively.

● If the DC input power cables are reversely connected, do not operate DC

SWITCH or the positive and negative connectors immediately. Wait until the night when solar irradiance declines and the PV string current drops to below

0.5 A. Then set DC SWITCH to OFF, remove the positive and negative connectors, and connect the DC input power cables correctly.

● The output of the PV strings connected to the inverter cannot be grounded.

Ensure that the PV output is well insulated to ground.

● PV modules and optimizers in the PV strings connecting to the same MPPT

must be of the same model and quantity.

● If power cables are not properly installed or routed during the installation of PV

strings and the inverter, the positive or negative terminals of PV strings may be short-circuited to ground. In this case, an AC or DC short circuit may occur and damage the inverter. The resulting device damage is not covered under any warranty.

Procedure

Before inserting the positive and negative connectors into the positive and negative DC input terminals of the inverter, ensure that DC SWITCH is set to OFF.

● 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 polarity 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 connected securely.

● 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 DC SWITCH is set to ON,

do not operate on DC SWITCH or the positive and negative connectors immediately. Otherwise, the device may be damaged. The resulting device damage is not covered under any warranty. Wait until the night when solar irradiance declines and the PV string current drops to below 0.5 A. Then set DC SWITCH to OFF, remove the positive and negative connectors, and connect DC input power cable correctly.

● 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 cable connection. If the voltage is greater than 1100 V DC, too many PV modules are connected in the same string.

● If PV strings are congured with optimizers, check the cable polarity by referring to the

Smart PV Optimizer Quick Guide
