2Installation Requirements
Dimensions
Angle Space
For ease of installing the SUN2000 on the mounting bracket, connecting cables to the bottom
of the SUN2000, and maintaining the SUN2000 in future, it is recommended that the bottom
clearance be greater than or equal to 300 mm and less than or equal to 730 mm. If the site
cable is hard, the space at the bottom is recommended to be within the range of 600 mm and
730 mm. If you have any questions about the distance, consult the local technical support
engineers.

1. Install the mounting bracket.
2. Install the SUN2000 on the mounting
bracket.
3. Tighten security Torx screws.
You are advised to
apply anti-rust paint on the
hole positions for protection.
3Installing the SUN2000
•The M12x40 bolt assemblies are delivered
with the SUN2000. If the bolt assembly
length does not meet the installation
requirements, prepare M12 bolt assemblies
by yourself and use them together with the
delivered M12 nuts.
•Before installing the mounting bracket,
remove the security Torx wrench from the
mounting bracket and save it for later use.
•This document introduces how to install the
SUN2000 on a support as an example. For
details about wall-mounted installation, see

•
If you connect a PE cable to the PE
point in the maintenance
compartment, you do not need to
prepare a PE cable separately but are
advised to use a four-core (U, V, W,
and PE) outdoor copper cable, M10
OT/DT terminals (U, V, and W), and

Preparing Cables
4.1
4Electrical Connections
Connect cables in accordance with the local installation laws and regulations.

Installing the PE Cable (on the Enclosure)
4.2
•It is recommended that the PE cable
be connected to a nearby PE point.
Connect the PE points of all
SUN2000s in the same PV array to
ensure equipotential connections to
PE cables.
•To enhance the corrosion resistance
of a ground terminal, you are advised
to apply silica gel or paint on it after
connecting the PE cable.
1. Loosen the screws on the maintenance
compartment door.
Opening the Maintenance Compartment Door
4.3
•Do not open the host panel of the SUN2000.
•Before opening the SUN2000 maintenance compartment door, turn off the downstream AC
output switch and two DC switches at the bottom.
•Do not open the maintenance compartment door in rainy or snowy days. If you must, take
protective measures to prevent rain or snow from entering the maintenance compartment.
•Do not leave unused screws in the maintenance compartment.
2. Open the maintenance compartment door
and adjust the support bar.
3. Remove the cover and hang it on the hook of the enclosure door.

6
Installing the AC Output Power Cable
4.4
•This document introduces how to install the four-core AC output power cable, which can be a
reference for installing the three-core cable. The three-core cable does not need a PE cable
installed in the maintenance compartment.
•To avoid damaging the rubber liner, do not route a cable with a crimped OT terminal directly
through it.
•Do not adjust the cable when the sealing nut is tightened. Otherwise, the rubber liner will
shift, which affects the IP rating of the device.
•Ensure that AC terminations are secured. Failing to do so may cause the SUN2000 to
malfunction or damage to its terminal block by issues such as overheating.
•If the SUN2000 is insecurely installed and the AC output power cable bears the pulling force,
ensure that the last cable bearing the force is the PE cable.
After the AC output power cable is installed, seal the cable gland.
Installing the DC Input Power Cable
4.5
Requirements for selecting DC input terminals
1. Evenly distribute DC input power cables on the DC input terminals controlled by the two DC
switches.
2. Maximize the number of connected MPPT circuits.

1. Crimp the metal contacts using crimping tool UTXTC0003 (Amphenol, recommended) or
UTXTC0002 (Amphenol).
2. Use the positive and negative Amphenol UTX metal contacts and DC connectors supplied with
the SUN2000. Using other positive and negative metal contacts and DC connectors may result
in serious consequences. The caused device damage is not covered under any warranty.
3. Before connecting the DC input power cable, label the cable polarities to ensure correct cable
connections. Otherwise, the SUN2000 may be damaged.
4. Measure the voltage at the DC input end using a multimeter. If the voltage is a negative value,
the DC input polarity is incorrect. Correct the polarity. If the voltage is greater than 1500 V, too
many PV modules are configured to the same string. Remove some PV modules.
5. If the DC input power cable is reversely connected and the DC switch is turned on, do not
perform operations 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 night when solar irradiance declines and the PV string current drops
to below 0.5 A. Then turn the two DC switches to the OFF position, remove the positive and
negative DC input power connectors, and correct the polarity of the DC input power cable.
•Ensure that the PV module output is well insulated to ground.
•Before inserting the positive and negative connectors respectively into the positive and negative
DC input terminals of the SUN2000, ensure that the DC voltage does not exceed 1500 V DC
using a multimeter and that the cable polarities are correct. Otherwise, the SUN2000 will be
damaged.

Installing the RS485 Communications Cable
4.6
1. When routing the communications cable, separate it from power cables and connect the
shield layer to the ground point to prevent communication from being affected.
2. The RS485 communications cable can connect to a terminal block or an RJ45 network port.
Select one in actual installation.
