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.

Preparing Cables

Antenna port (ANT)

4Connecting Cables

If the antenna washer is not installed, the antenna will lose the waterproof function.

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.

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.
