Determining the Installation Position

1.1

1. The information in this document is subject to change without notice. Every effort has been

made in the preparation of this document to ensure accuracy of the contents, but all statements,

information, and recommendations in this document do not constitute a warranty of any kind,

express or implied.

2.2

OT-M6

PE terminal

1. It is recommended that an 8 mm2, 10

mm2, 8 AWG or 7 AWG outdoor

copper-core cable be used as a

ground cable. Ground cables must

be securely connected.

2. It is recommended that the ground

cable be connected to a nearby

ground position. For a system with

multiple inverters connected in

parallel, connect the ground points of

all inverters to ensure equipotential

connections.

3. To prevent corrosion, apply silica gel

or paint to the PE terminal after

connecting the PGND cable.

NOTE

Both the shell and maintenance compartment of the inverter provide a ground point. Select either

for connecting the ground cable.

•If you connect a ground cable to the ground point on the chassis shell, you are recommended to

use a four-core (L1, L2, L3, and N) outdoor copper-core cable for the SUN2000-33KTL/33KTL-

E001. If you connect a ground cable to the ground point in the maintenance compartment, you

are recommended to use a five-core (L1, L2, L3, N, and PE) outdoor copper-core cable.

•If you connect a ground cable to the ground point on the chassis shell, you are recommended to

use a three-core (L1, L2, and L3) outdoor copper-core cable for the SUN2000-30KTL-A/40KTL.

If you connect a ground cable to the ground point in the maintenance compartment, you are

recommended to use a four-core (L1, L2, L3, and PE) outdoor copper-core cable.

•You need to prepare OT terminals by yourself: The OT terminal corresponding to the SUN2000-

33KTL/33KTL-E001 AC output power cable is of M6 model and matches a cable with the

maximum cross-sectional area of 25 mm2. The OT terminal corresponding to the SUN2000-

30KTL-A/40KTL AC output power cables is of M8 model and matches a cable with the maximum

cross-sectional area of 35 mm2. The OT terminal corresponding to the ground cable is of M6

model and matches a cable with the maximum cross-sectional area of 25 mm2.

rib at the chassis base.

2. Do not leave unused screws in the chassis.

3. Do not open the host panel of the inverter.

4. Before opening the maintenance

compartment door, switch off the

downstream AC output circuit breaker and

DC SWITCH.

NOTICE

2. Open the maintenance compartment door and

install the support bar available in the fitting bag

bound to the reinforcing rib at the chassis base.

3. Remove the AC terminal cover.

4. Remove an appropriate length of the jacket and insulation layer from the AC output cable using

a wire stripper.

7. Remove the locking cap from the AC OUTPUT waterproof cable connector at the inverter

bottom and remove the plug from the locking cap.

8. Route the AC output power cable into the locking cap and the AC OUTPUT connector at the

inverter bottom.

9. Connect the wires of the AC output cable for the SUN2000-33KTL/33KTL-E001 to L1, L2, L3,

and N on the AC terminal block. Secure the screws using a 10 mm socket wrench. Connect the

wires of the AC output cable for the SUN2000-30KTL-A/40KTL to L1, L2, and L3 on the AC

terminal block. Secure the screws using a 13 mm socket wrench. If you connect a ground cable

to the ground point in the maintenance compartment, tighten the ground screw using an M6

torque screwdriver.

5. Insert the exposed core wires into the crimp area of the OT terminal and crimp them using

hydraulic pliers.

6. Wrap the wire crimp area with heat shrink tubing or PVC insulation tape.

If heat shrink tubing is used, put it through the power cable and then crimp the OT terminal.

•Ensure that the AC output power cable is connected securely. Otherwise, the inverter may fail to

operate or experience a fault that will damage the terminal block. For example, the inverter may

generate heat during operation due to unreliable connection.

•If the nverter 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.

NOTE

Installing DC Input Power Cables

2.3

1. Use the positive and negative metal contacts and DC connectors supplied with the SUN2000.

Using other models of positive and negative metal contacts and DC connectors may result in

serious consequences. The caused device damage is not covered under any warranty or

service agreement.

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

H4TC0001 (Amphenol). Crimp the metal stamping contacts using crimping tool H4TC0002

(Amphenol). Choose the crimping tools that fit the metal contact types. Do not mix up the tools.

3. Before connecting DC input power cables, label the cable polarities to ensure correct cable

connections. If the cables are connected incorrectly, the SUN2000 may be damaged.

4. Insert the crimped metal contacts 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.

5. Connect the positive and negative connectors to the appropriate positive and negative DC input

terminals. Then pull back the DC input power cables to ensure that they are connected securely.

6. If the DC input power cables are reversely connected and the DC SWITCH is ON, do not turn off

the DC SWITCH immediately. Otherwise, the inverter may be damaged and the damage is

beyond the warranty scope. Wait until the PV string voltage reduces to the safety range (below

60 V DC). Then, turn off the DC SWITCH,remove the positive and negative connectors, and

rectify the connection.

NOTICE

WARNING

•Ensure that the PV string is well insulated to the ground.

•Before inserting the positive and negative connectors respectively into the positive and negative

DC input terminals of the inverter, check that the DC voltage does not exceed 1000 V DC using

a multimeter and that the cables are connected correctly. Otherwise, the inverter will be

damaged.

Selecting a Communication Mode

Installing RS485 Communications Cables

2.5

1. When routing communications cables, ensure that communications cables are separated from

power cables and away from interfering source to prevent communication from being affected.

2. RS485 communications cables can be connected to the terminal block or RJ45 ports.

Connecting to the terminal block is recommended.

NOTICE

1. Remove an appropriate length of the insulation layer from the cable using a wire stripper.

Method 1: Connecting to the terminal block (recommended)

The DJYP2VP2-22 2x2x1 network cable or a communications cable with a cross sectional area of

1 mm2and external diameter of 14–18 mm is recommended.

2. Remove the locking caps from the COM1 and COM2 waterproof cable connectors at the inverter

bottom and remove the plugs from the locking caps.

3. Route the cables through the locking caps and then the COM1 (RS485 IN) and COM2 (RS485

OUT) connectors at the inverter bottom.

4. Connect the input end to terminals 5 and 7 on the terminal block and connect the output end to

terminals 6 and 8 on the terminal block. Tighten the terminals using an M3 flat-head screwdriver

to a torque of 0.5 N·m. Connect the shield layer to the ground point and tighten the screw using

an M4 Phillips torque screwdriver to a torque of 1.2 N·m.

6. Use a torque wrench with an open end of 33 mm to tighten the locking caps to a torque of 7.5

N·m, and seal the waterproof connector.

5. Bind the RS485 communications cables.

When connecting the shielded cable, choose whether to crimp the OT-M4 terminal based on site

requirements.
