Installing the SUN2000L
3.3
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.
You are advised to apply anti-rust paint
on the hole positions for protection.
•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.

•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 voltage of the SUN2000L may result in
electric shocks.
Installing the WLAN Antenna
3.4
Ensure that the WLAN antenna is installed
securely.

Installing the PE Cable
4.2
Do not connect the neutral wire to the enclosure as a PE cable. Otherwise, electric shocks will be
caused.
•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.
1. Connect the AC output power cable to the AC connector.
Installing the AC Output Power Cable
4.3
Ensure that the protection layer of the AC output power cable is in the connector, and that the
exposed core wire is totally inserted into the cable hole and connected securely. Failing to do so
may cause SUN2000L malfunction or damage.

Installing the DC Input Power Cable
4.4
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 UTXTC0005 (Amphenol)
or H4TC0001 (Amphenol). Crimp the metal stamping forming contacts using crimping tool
H4TC0003 (Amphenol, recommended) or H4TC0002 (Amphenol).
3. DC terminal model (cold forming metal terminal): straight male HH4CMD5TM and straight female
HH4CFC5DM; DC terminal model (stamping forming metal terminal): straight male HH4CMD4TMS
and straight female HH4CFD4TMS.
4. TheSUN2000Lopencircuitvoltagemustalwaysbelowerthanorequalto600VDC.
5. Before installing the DC input power cable, label the cable polarities correctly to ensure correct cable
connections.
6. Use the positive and negative metal terminals and black DC connectors supplied with the inverter.
Using incompatible positive and negative metal terminals and DC connectors may result in serious
consequences. The caused device damage is not covered under any warranty.
7. 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.
