NOTE
If multiple inverters need to be installed, see SUN2000L-(3KTL, 4KTL, 5KTL)-CN
User Manual for the installation dimensions.
NOTE
Support-mounted Installation
You are advised to
apply anti-rust paint
on the hole
positions for
protection.
Prepare M8 stainless bolt assemblies (including flat washers, spring washers, and M8 bolts) with
appropriate lengths as well as matched flat washers and nuts based on the support specifications.

Installing the SUN2000L
2.3
1. Install the SUN2000L on the mounting bracket. 2. Tighten screw assemblies. 3. (Optional) Install an anti-theft lock.
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.

NOTICE
If the 4G module has a built-in SIM card, there is no need to install a SIM card.
After installed and powered on, the 4G module can access the network without being
commissioned.
The USB-4G port is available only for a 4G module, rather than a USB data cable.
Install the SIM card in the direction shown by the silk screen and arrow on the slot.
Press the SIM card until it snaps into place and locked, which means that the SIM
card is installed correctly.
To remove the SIM card, push it inwards. The SIM card will spring out automatically.
Ensure that the WiFi antenna is installed securely.
The 4G module and WiFi antenna cannot be used
at the same time.

Connect cables in accordance with the installation laws and regulations of the country or region where the project is located.
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.
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.
NOTICE
Reinstalling the 4G module enclosure, ensure that the
buckle springs back to the original position.
Avoid drilling holes in the utility
pipes and/or cables attached
to the back of the wall.

Installing the PE Cable
3.2
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.

2. Connecting the DC Input Power Cable
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.

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.
