Installing the SUN2000
2.2
Prepare an anti-theft lock suitable for the lock hole diameter (Ф8 mm) by yourself. An outdoor
waterproof lock is recommended.
NOTE
2. Install the SUN2000 on the mounting bracket. 3. (Optional) Install an anti-
theft lock.
•M6x60 expansion bolts are delivered with the SUN2000. If the length and amount of the bolts
do not meet installation requirements, prepare M6 stainless steel expansion bolts by yourself.
•Loosen the nuts, flat washers, and spring washers of the two expansion bolts below.
NOTE
1. Install the mounting bracket.
When drilling holes, avoid the water pipes and power cables buried in the wall.

4
•Connect cables in accordance with the local installation laws and regulations .
•Before connecting cables, ensure that the DC switch on the SUN2000 and all the switches
connecting to the SUN2000 are set to OFF position. Otherwise, the high voltage of the
SUN2000 may result in electric shocks.
Preparing for Installation
3.1
•The PE point at the AC output port is used only as a PE equipotential point, not a substitute for
the PE point on the enclosure.
•It is recommended that silica gel or paint be used around the ground terminal after the PE cable
is connected.
NOTE

Ensure that the protection layer of the AC output power cable is inside the connector, the core
wires are totally inserted into the cable hole, and the cable is connected securely. Failing to do so
may cause device malfunction or damage.
1. Connect the AC output power cable to the AC connector.

Installing DC Input Power Cables
3.4
3. Check the route of the AC output power cable.
1. Use the Amphenol Helios H4 PV connectors supplied with the SUN2000. If the PV connectors
are lost or damaged, purchase the connectors of the same model. The device damage caused
by incompatible PV connectors is not covered under any warranty.
2. Ensure that the PV module output is well insulated to ground.
3. The DC input voltage of the SUN2000 shall not exceed 1100 V DC under any circumstance.
4. Before installing the DC input power cable, label the cable polarities to ensure correct cable
connections.
5. Use the positive and negative metal contacts and black DC connectors supplied with the
SUN2000. 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.
6. If the DC input power cable is reversely connected, do not operate the DC switch as well as
positive and negative connectors immediately. Failing to do so may cause device damage, which
is not covered under any warranty. Wait until the night when solar irradiance declines and the PV
string current drops to below 0.5 A. Then set the DC switch to the OFF position, remove the
positive and negative connectors, and correct the polarities of the DC input power cable.

8
Ensure that the locking
nut is secured.
Ensure that the cables are
correctly connected.
(The DC voltage of a multimeter
should not be less than 1100 V).

(Optional) Installing the Signal Cable
3.6
•Not all SUN2000 models are delivered with
the signal cable connector.
•When laying out the signal cable, separate it
from the power cable and keep it away from
strong interference sources to avoid strong
communication interference.
•Ensure that the protection layer of the cable is
inside the connector, surplus core wires are
cut off from the protection layer, the exposed
core wire is totally inserted into the cable hole,
and that the cable is connected securely.
•If the Smart Dongle is configured, you are
advised to install the Smart Dongle before
connecting the signal cable.
