AC Module System Installation Manual
Rev. 1.0
•
Use proper equipment, connectors, wires and buttresses for the installation of the module.
•
To reduce the risk of accidents, install the AC modules during mild weather. For raining or snowy
days, electric shock hazard exists. For windy days, there is a difficulty to move the AC modules.
•
To prevent the risk of injury, do not apply pressure on the module (ex. placing heavy objects or
stepping on the module).
•
To prevent the risk of injury, do not drop the module. Modules must be gently handled and
placed down with care.
•
For proper operation, do not scratch the coating surface of the frame. It may increase the
corrosion of the frame.
•
For proper operation, do not artificially concentrate sunlight on the module surface.
•
Addition of holes in the frame or glass of the module may decrease the strength and integrity of
the frame or glass.
•
Do not remove warning labels. Do not apply a shock to micro inverter of the module or pull the
AC cable. Do not remove the labels attached on the module except the detachable label for
installation map .
•
Store the module in its original package until installation.
•
Do not use any kind of oil or lubricant on the module's any parts, It can defect the AC Module.

•
AC modules shall be mounted with racking and mounting products certified and listed for
system fire class rating in accordance with UL1703 edition 2014 and UL2703 edition 2014.
•
The System Fire Class Rating of the module or panel in a mounting system in combination with a
roof covering must complete with requirements to achieve the specified System Fire Class
Rating for a non-BIPV module or panel.
•
To make better air circulation along the backside of the AC module, it is recommended to install
the PV rack with a gap of at least 4 inches (100mm) between the back of the module and roof
surface. It might affect UL listing and fire class if it is less than 4 inches (100mm).
•
Please check voltage range for use before installation of AC modules and EnerBox2. Refer to 9
Product Specifications.
•
When installed on a roof, the PV module must be mounted over a fire-resistant roof. The fire
resistance of the PV module is class C according to ANSI/UL790.
•
It is recommended to check with local authorities for fire safety guidelines and requirements for
any buildings or structures on to which the panels will be installed.
•
Both AC and DC voltage sources are terminated inside this equipment.
•
Each circuit must be individually disconnected before servicing.
•
When the photovoltaic array is exposed to light, it supplies a DC voltage to this equipment.
•
AC module arrays need to be connected only to a dedicated branch circuit.
