to the back of the wall.
Wall-mounted Installation
If the bottom of the mounting plate does not snap into place, push the SUN2000L from the
front until the bottom of the mounting plate snaps into the mounting bracket.
The anti-theft lock needs to be prepared by the customer.
1. Install the SUN2000L on the
mounting bracket. 2. Tighten screw assemblies. 3. (Optional) Install an anti-theft lock.
3Connecting Cables
Preparing Cables
3.1
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.
Recommended: Apply silica gel or paint around a ground
terminal after connecting the ground cable.

3.2
Prepare cables based on site requirements.
Do not connect the neutral wire to the enclosure as a PE
cable. Otherwise, electric shocks will be caused.
Connect cables in accordance with the installation laws and regulations
of the country or region where the SUN2000L is located.
Before connecting cables, ensure that the DC switch on the SUN2000L
and all the switches connecting to the SUN2000L are OFF. Otherwise,
the high voltage of the SUN2000L may result in electric shocks.

Installing the DC Input Power Cable
3.4
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
H4TC0001 (Amphenol). Crimp the metal cold stamping contacts using crimping tool
H4TC0002 (Amphenol). Choose the crimping tools that fit the metal contact types. Do not
mix up the tools.
3. TheSUN2000LDCinputvoltage mustalways belower than orequalto600VDC.
4. Before installing the DC input power cable, label the cable polarities correctly to ensure
correct cable connections.
5. Use the positive and negative connectors supplied with the SUN2000L.
6. 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 SUN2000L.

NOTICE
When laying out signal cables, separate them from power cables to avoid strong signal interference sources.
The protection layer of the signal cable is in the connector. Surplus core wires are cut off from the protection layer. The exposed core wire
is totally inserted into the cable hole and connected securely.
Do not confuse the connector to the COM port and the connector to the ALARM port.
If a connector needs to connect to only one signal cable, block the unused cable hole in the seal using a cap and tighten the cable gland.
If a connector needs to connect to two signal cables, ensure that the cables have the same outer diameter.

NOTICE
To remove the AC connector from the SUN2000L, perform the operations in reverse order.
The right figure shows how to remove a plug insert.
NOTE
The battery voltage will result in fatal injury. Use dedicated
insulation tools to terminate cables.
Ensure that the battery cable is correctly connected. Avoid
reverse polarity.
If the battery is connected with reverse polarity, the inverter
may be damaged.
Assemble the blue positive and negative connectors by following the instructions in section 3.4 "Installing the DC Input Power Cable."
Pull the battery cable back to ensure
that it is connected securely.

4Verifying the Installation
Before turning on the AC switch betweenthe SUN2000L and the power grid, checkthat the
AC voltage on the power grid sideof the AC switch is within the specified range.
After turning on the AC switch, turn on the DC switch within 1 minute. Otherwise, the
SUN2000L willstart to export powerto the power grid. If you turn on the DC switch in this
case, the SUN2000L will shut down first, and then restart to export power to the power grid.
