Installation Space
2.2
For ease of installing the SUN2000
on the mounting bracket,
connecting cables to the bottom of
the SUN2000, and maintaining the
SUN2000 in future, it is
recommended that the bottom
clearance be between 600 mm
(23.62 in.) and 730 mm (28.74 in.).

NOTE
3Installing the SUN2000
•The SUN2000 mounting bracket has four groups of tapped holes, each group containing four
tapped holes. Mark any hole in each group based on site requirements and mark four holes in
total. Two round holes are preferred.
•The SUN2000 is delivered with M12x60 expansion bolts and M12x40 bolt assemblies. If the bolt
assembly length does not meet the installation requirements, prepare M12 bolt assemblies by
yourself and use them together with the delivered M12 nuts.
•Before installing the mounting bracket, remove the security torx wrench from the mounting
bracket and save it for later use.
NOTE
Round
holes

•To prevent dust inhalation or contact with eyes, wear safety goggles and an anti-dust mask
when drilling holes.
•Clean up any dust in and around the holes using a vacuum cleaner and measure the
distance between holes. If the holes are inaccurately positioned, drill new set of the holes.
•Level the head of the expansion sleeve with the concrete wall after removing the bolt, spring
washer, and flat washer. Otherwise, the mounting bracket will not be securely installed on
the concrete wall.
NOTICE
Wall-mounted Installation
Avoid drilling holes in the utility pipes and/or cables attached to back of the wall.

Support-mounted Installation
You are advised to apply anti-rust paint on the hole positions for protection.

gun
Pay attention not to damage the core wire when stripping a cable.
The cavity formed after the conductor crimp strip of the OT terminal is crimped must wrap the
core wires completely. The core wires must contact the OT terminal closely.
Wrap the wire crimping area with heat shrink tubing or PVC insulation tape. The following figure
uses heat shrink tubing as an example.
When using the heat gun, protect devices from being scorched.

Installing the Tube Fittings (Using AC OUTPUT as an Example)
4.2
The tube specifications should comply with the waterproof connector specifications. For example,
for a 2 in. waterproof connector, prepare a 2 in. tube. The tube appearance shown in the following
figure is for reference only. The actual tube prevails.

1. Remove the AC filter and save the screws for later use.
2. Remove the cable gland and cap from the waterproof connector, and then remove the waterproof
connector.
3. Secure the tube fittings.
4. Install the AC filter in the original position.
•AC filter operation is required only for the AC OUTPUT waterproof connector, not required for
other waterproof connectors.
•Following are the reference torque values for the waterproof connector and tube. Observe the
requirements of the specific manufacturer, if any.
−AC OUTPUT and COM ports: 7.5 N·m (plastic) or 10 N·m (metal)
−RESERVE port: 3.75 N·m (plastic) or 6.25 N·m (metal)
NOTE
For ease of connecting the AC output power cable, you are advised to remove the nut assembly
from the AC terminal and save it for later use, and then route the cable through the waterproof
connector.

Installing the Ground Cable
5.1
•Both the maintenance compartment and chassis shell of the SUN2000 provide a PE point.
Select either for connecting the ground cable. For details about how to connect a ground cable
to the PE point in the maintenance compartment, see section " 5.3 Installing AC Output Power
Cables."
•You are advised to use outdoor copper-core cables with a cross-sectional area of 6 AWG and
M6 OT terminals. The ground cable must be secured.
•It is recommended that the ground cable be connected to a nearby PE point. For a system with
multiple SUN2000s connected in parallel, connect the PE points of all SUN2000s to ensure
equipotential connections to ground cables.
•Recommended: To enhance the corrosion resistance of a ground terminal, silica gel or paint
might needed.
NOTE
1. Connect the ground cable to the PE point (on the chassis shell).
2. Connect the ground cable to the PV side ground point.
