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 the
user manual.

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.

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/DT
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.
•Sufficient slack should be provided in the
PE cable to ensure that the last cable
bearing the force is the PE cable when
the AC output power cable bears pulling
force due to force majeure.

Ensure that the AC
output power cable
and terminal clamp

Installation Procedure (Using the OT/DT Terminal)
After the AC output power cable is installed, seal the cable gland.

Installation Procedure (Using the Terminal Clamp)
Installing the DC Input Power Cable
4.5
When DC inputs are not fully configured, the input terminals should meet the following requirements:
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.
For example, if the number of input routes is 6–11, the recommended DC input terminals are as follows:
After the AC output power cable is installed, seal the cable gland.
NOTICE
The SUN2000 provides 12 DC
input terminals, which are
controlled by its two DC switches.
DC SWITCH 1 controls DC input
terminals 1–6 (MPPT1–3) and DC
SWITCH 2 controls DC input
terminals 7–12 (MPPT4–6).

8
1. 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.
2. Before connecting the DC input power cable, label the cable polarities to ensure correct cable
connections. Otherwise, the SUN2000 may be damaged.
3. 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.
4. 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.

Selecting the Communications Mode
4.6
•If PLC is selected, no RS485 communications cable is required to connect to the SUN2000, but
the AC power cable needs to connect to the SmartLogger2000 that supports PLC.
•If RS485 is selected, connect an RS485 communications cable to the SUN2000, but the AC
power cable does not need to connect to a SmartLogger2000 that supports PLC.
The SUN2000 supports PLC and RS485 communications modes, but you can only choose one of them.
NOTICE
NOTE
•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.
WARNING

Installing the RS485 Communications Cable
4.7
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.

(Optional) Installing the Tracking System Power Cable
4.8
•The tracking system should be equipped with an overcurrent protective device/component. The
power cable between the device/component and wiring terminal should be no longer than 2.5 m.
•The tracking system is powered by the three-phase AC power grid with a rated voltage of 800 V.
•Keep inflammable materials away from the power cable.
•The power cable must be protected with a conduit to prevent short circuits caused by insulation
layer damage.
