Connect cables in accordance with the installation laws and regulations of the country or
region where the SUN2000 is located.
Before connecting cables, ensure that the DC switch on the SUN2000 and all the switches
connecting to the SUN2000 are OFF. Otherwise, the voltage of theSUN2000 may result in
electric shocks.

Installing the PE Cable
4.2
Ground
point
Click
Do not connect the neutral wire to the enclosure as a PE cable. Otherwise, electric shocks will be
caused.
Recommended: Apply silica gel or paint around a ground terminal after connecting the ground
cable.
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.
NOTE
1. Connect the AC output power cable to the AC connector.
Installing the AC Output Power Cable
4.3
Ensure that the protection layer of the AC output power cable is in the connector, and that the
exposed core wire is totally inserted into the cable hole and connected securely. Failing to do so
may cause SUN2000 malfunction or damage.

Installing the DC Input Power Cable
4.4
1. Ensure that the PV string is well insulated to ground.
2. The metal contacts supplied with the DC connectors are either cold forming contacts or
stamping forming contacts. Crimp the metal cold forming contacts using crimping tool
UTXTC0005 (Amphenol) or H4TC0001 (Amphenol). Crimp the metal stamping forming contacts
using crimping tool H4TC0003 (Amphenol, recommended) or H4TC0002 (Amphenol).
3. Choose the crimping tools that fit the metal contact types. Do not mix up the tools.
4. The SUN2000 open circuit voltage must always be lower than or equal to 600 V DC.
5. Before installing the DC input power cable, label the cable polarities correctly to ensure correct
cable connections.
6. Use the positive and negative metal terminals and black DC connectors supplied with the
inverter. Using incompatible positive and negative metal terminals and DC connectors may
result in serious consequences. The caused device damage is not covered under any warranty.
7. If polarity of the DC input power cable is reversed and the DC switch is ON, do not turn off the
DC switch immediately or unplug positive and negative connectors. The device may be
damaged if you do not follow the instruction. This damage is not covered under any warranty or
service agreement. Wait until the solar irradiance declines at night and the PV string current
reduces to below 0.5 A, and then turn off the DC switch and remove the positive and negative
connectors. Correct the string polarity before reconnecting the string to the SUN2000.

When laying out communications cables, separate them from power cables to avoid strong
signal interference sources.
Ensure that the exposed core wire is totally inserted into the cable hole and connected securely.
If only one signal cable needs to be connected, block the unused cable hole on the seal using
a cap and tighten the cable gland.
If two signal cables are required, ensure that they have the same outer diameter.

6Powering On the System
Before turning on the AC switch between the SUN2000 and the power grid, check whether the
AC voltage is within the specified range.
After turning on the AC switch, turn on the DC switch within 1 minute. Otherwise, the SUN2000
will start to export power to the power grid. If you turn on the DC switch in this case, the
SUN2000 will shut down first, and then restart to export power to the power grid.
1. Turn on the AC switch between the SUN2000 and the power grid.
2. Turn on the DC switch between the PV string and the SUN2000 if there is any.
3. Turn on the DC switch at the bottom of the SUN2000.
4. Observe the LEDs to check the SUN2000 operating status. All status labels are available on
the left side of the SUN2000.
