2.Safety
2.1 Intended Use
The Suntrio-TL series inverters are PV inverter which converter the direct current of a PV array
into alternating current and feed this into the electricity grid.
The inverters are designed according to the safety rules. However, improper use, alteration or
modication may cause lethal hazards for the operator or third parties, or may result in damage
to the units and other property. SAJ is not responsible for the loss and invalidate these warranty
claims.
Figure 2.1 Grid-tie Solar System with Suntrio inverter
2.2 Safety Precaution
DANGER
● DANGER due to electrical shock and high voltage
● Do not touch the operating component of the inverter; it might result in burning or death.
● To prevent risk of electric shock during installation and maintenance, please make sure that all AC
and DC terminals are plugged out.
● Do not touch the surface of the inverter while the housing is wet, it might lead to electrical shock.
● Do not stay close to the inverters while there are severe weather conditions including storm, lighting,
etc.
● Before opening the housing, the SAJ inverter must be disconnected from the Grid and PV generator;
you must wait at least five minutes to let the energy storage capacitors fully discharged after
disconnecting from power source.

WARNING
● The installation, service, recycling and disposal of the inverters must be performed by qualied
personnel only in compliance with national and local standards and regulations.
● Any unauthorized actions including modification of product functionality of any form
may cause lethal hazard to the operator, third parties, the units or their property. SAJ is not
responsible for the loss and deny these warranty claims.
● Suntrio inverters must only be operated with PV generator. Do not connect any other source of
energy to the inverters.
● Be sure that the PV generator and inverter are well grounded in order to protect properties and
persons.
CAUTION
● The PV inverter will become hot during operation. Please don’t touch the heat sink or
peripheral surface during or shortly after operation.
● Risk of damage due to improper modications.
● Never modify or manipulate the inverter or other components of the system.
NOTICE
● The PV inverter is designed to feed AC power directly to the public utility power
grid; do not connect AC output of the inverter to any private AC equipment.

4.2 Mounting Instructions
Figure 4.2 Mounting Instructions
Mounting on a solid surface out door or indoor.
● Site altitude is less than 2,000m above the sea level.
● The mounting location must be clear and safely accessible at all times without the use
of additional aids such as scaffolding or lifting platforms. If this is not the case, service
work may be restricted.
● Mount vertically or tilted backwards by max. 15°
● The connection area must point downwards.
● Never install the inverter forward tilt, sideways tilt, horizontally or even upside down.
● Install the inverter at eye level for convenience checking the LCD display and possible
maintenance activities.
● Given the weight of the device, this will facilitate disassembly for service work.
● The ambient temperature should be below 45°C to ensure optimum operation. Choose
locations with sufcient air exchange. Ensure additional ventilation, when necessary.
● Do not expose the inverter to direct solar irradiation as this could cause power
derating due to overheating.
● In order to avoid audible vibrations in living areas, do not mount the unit on
plasterboard walls or similar.
● Observe the recommended clearances to walls, other inverters or other objects, as
shown in the follow diagram. That ensures sufcient heat dissipation and gives you
enough space to unplug the PV Connector, communication port and operate the DC-
switch.

5.4 Miniature circuit breaker
DANGER
When more than one inverter is connected in parallel to the same miniature circuit-breaker, the
protective unction of the miniature circuit-breaker is no longer guaranteed. This could result in
a cable re or destruction of the inverter.
●Never connect several inverters to a single miniature circuit-breaker.
In order to securely disconnect the inverter from the PV generate and the public-Grid, SAJ
recommend to install circuit breaker at DC Input and AC output as gure 2.1 shown.
