2. SAFETY AND WARNINGS
1. All persons who are responsible for mounting, installation, commissioning,
maintenance, tests, and service of HYPONTECH inverter products must be suitably
trained and qualified for corresponding operations. They MUST be experienced and
have knowledge of operation safety and professional methods. All installation
personnel must have knowledge of all applicable safety information, standards,
directives, and regulations.

User Manual 6
2. The product must ONLY be connected and operated with PV arrays of protection
class II, in accordance with IEC 61730, application class A. The PV modules must also
be compatible with this product. Power resources other than compatible PV arrays
MUST not be connected and operate with the product.
3. When designing or constructing a PV system, all components MUST remain in their
permitted operating ranges, and their installation requirements MUST always be
fulfilled.
4. Under exposure to sunlight, the PV array may generate dangerous output in DC
voltage. Contacts with the DC wires, conductors and live components in the inverter
may result in lethal shocks.
5. High voltages in inverter could cause lethal electrical shocks. Before proceeding any
work, including maintenance and/or service, on the inverter, fully disconnect it from
all DC input, AC grid and other voltage sources. There MUST be a 5-minute waiting
time after the full disconnection.
6. The DC input voltage of the PV array MUST never exceed the maximum input
voltage of the inverter.
7. DO NOT touch parts of the inverter during operation as heat will be induced and
these parts will exceed 60℃.

4. 4INSTALLING
4.1 Installation Requirement
1. Please install the inverter(s) in places that can avoid inadvertent contact.
2. Installation method, location and surface must be fitting for the inverter’s weight and
dimensions.
3. Please install the inverter in an accessible location for operation, future maintenance
and service.
4. The inverter performance peaks at ambient temperature lower than 45℃.
5. When installing in residential or domestic environment, it is recommended to install
and mount the inverter on a solid, concrete wall surface. Mounting the inverter on
composite or plaster boards or walls with similar materials would induce noise during
its operation and is therefore not recommended.
6. DO NOT cover the inverter NOR place any objects on top of the inverter.
7. To ensure sufficient room for heat dissipation and maintenance, the clearing space
between inverter(s) and other surroundings is indicated below for reference:

User Manual 10
8. Avoid direct exposure to sunlight and rain and snow layup.
4.2 Mounting Location
1. DO NOT mount the inverter near any inflammable materials.
2. DO NOT mount the inverter near any explosive materials.
3. DO NOT mount the inverter on tilting surface over 15°backwards. Please mount the
inverter on a vertical wall surface.
4. DO NOT mount the inverter on any surfaces tilting forward or to either sides.
5. DO NOT mount the inverter on a horizontal surface.
6. For easy installation and operation, please mount the inverter on a height that the
display could match eye level.
7. The bottom side where all commissioning terminals are equipped MUST always point
downwards.

11 User Manual
4.3 Mounting
Moving the inverter：
1. Use machinery or manpower to move the inverter according to the
situation on site.
2. It is recommended to move the inverter manually by at least two workers.
Protective shoes, gloves and other PPE’s (Personal Protective
Equipment ) are highly recommended. Focus on the pivot of the inverter
and prevent tiling the inverter.
3. When using lifting machinery, thread the rope through two lifting
handles on the upper side of the inverter. Pause when lifting the
inverter up to 100 mm above the ground, ensure tightness of rope, then
lift to the destination.
Wall-mounting the inverter
1. Use the mounting bracket as a template and drill holes of 10mm diameter and
70mm depth.
2. Fix the mounting bracket with the screws and expansion bolts packed in mounting
accessories.
3. Hold onto the handles on the inverter and tilt it slightly forward. Hang up the inverter
and attach it to the mounting bracket. Check both sides of the heat sink to ensure its
stably attached.
4. Observe from above, ensure the inverter has been securely attached to the bracket.
5. Use M5 screws (T25 screwdriver, torque 2.5 Nm) to attach the heat sink fins to the
mounting bracket.
It is recommended to attach the anti-theft lock to the inverter. Lock diameter φ4- 5.5mm
recommended.

User Manual 12
Racket-mounting the inverter:
In the same way as wall-mounting the inverter, only replace the expansion
bolts and screws with M10*45 Stainless steel full thread screw assembly (The
assembly incl. bolt, nut, flat washer, spring washer is not included in the
package)
4.4 Installing the secondary PE cable
1. Insert the grounding conductor into the suitable OT terminal lug and crimp the
contact.
2. Align the terminal lug with the grounding conductor and the ground washer on the
screw. The teeth of the ground washer must be facing the housing.
3. Tighten it firmly into the housing (M6 PE terminal, screwdriver type: Pan head,
torque: 4.5Nm).

5. 5COMMISSIONING
5.1 Safety Instructions
1. Measure the frequency and voltage of grid connection and make sure they follow the
inverter’s grid connection specifications.
2. An external circuit-breaker on the AC side (or a fuse) at 1.25*AC rated current is
strongly recommended.
3. Reliability of all earth connections must be tested and valid.
4. Before commissioning, disconnect the inverter and the circuit-breaker or fuse, and
prevent accidental reconnection.
