5.1 Safety instruction
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
Do not install the inverter on easily flammable materials and
where flammable materials are stored.
Risk of burns due to hot enclosure parts
Mount the inverter in such a way that it cannot be touched
inadvertently.
All electrical installations shall be done in accordance with the local and
national electrical codes. Do not remove the casing. Inverter contains no
user serviceable parts. Refer servicing to qualified service personnel. All
wiring and electrical installation should be conducted by a qualified
service personnel.
Carefully remove the unit from its packaging and inspect for external
damage. If you find any imperfections, please contact your local dealer.
Be sure that the inverters connect to the ground in order to protect
property and personal safety.
The inverter must only be operated with PV generator. Do not connect
any other source of energy to it.
Both AC and DC voltage sources are terminated inside the PV Inverter.
Please disconnect these circuits before servicing.
This unit is designed to feed power to the public power grid (utility) only.
Do not connect this unit to an AC source or generator. Connecting
Inverter to external devices could result in serious damage to your
equipment.
When a photovoltaic panel is exposed to light, it generates a DC voltage.
When connected to this equipment, a photovoltaic panel will charge the
DC link capacitors.
Energy stored in this equipment's DC link capacitors presents a risk of
electric shock. Even after the unit is disconnected from the grid and
photovoltaic panels, high voltages may still exist inside the PV-Inverter.
Do not remove the casing until at least 5 minutes after disconnecting all
power sources.
Although designed to meet all safety requirements, some parts and
surfaces of Inverter are still hot during operation. To reduce the risk of
injury, do not touch the heat sink at the back of the PV-Inverter or nearby
surfaces while Inverter is operating.
5.2 Selecting the Installation Location
11) Notice the minimum clearances of the inverter. (Refer to 3.3
Dimensions and Fig.5.2 Required Clearances).
This is guidance for installer to choose a suitable installation location, to
avoid potential damages to device and operators.
1) The wall selected to install the inverter must be strong and firm enough
to support and bear the weight of the inverter for a long period time.
(Refer to Chapter 11 Specifications)
2) The location selected must be suitable for inverters' dimension. (Refer to
3.3 Dimensions and Fig.5.2 Required Clearances)
3) Do not install the inverter on structures constructed of flammable or
thermo labile materials.
4) Never install the inverter in environment of little or no air flow, nor dust
environment.
5) The Ingress Protection rate is IP65 which means the inverter can be
installed outdoors and indoors.
6) Do not expose the inverter to direct sunlight, in order to avoid the power
and efficiency derating caused by excessive heating.
7) The humidity of the installation location should be 0~95% without
condensation.
8) The ambient temperature of the inverter should be -25
℃
~+60
℃.
9) The installation location must be freely and safely to get at all times.
10) Vertically installation and make sure the connection of inverter must be
downwards. Never install horizontal and avoids forward and sideways
tilt.( Refer to drawings below)
