If you have any question or problem when you read the

following information, please contact DASS Tech Co., Ltd.

Note

Outlines of this chapter

Safety instruction

It mainly introduce the safety instruction when install and operate the

equipment.

Symbols and signs

It mainly introduce the safety symbols on the inverter.

1.1. Safety instructions

Read and understand the instructions of this manual, and be familiar with

relevant safety symbols in this chapter, then start to install and troubleshoot the

equipment.

According to the national and state requirements, before connecting to the

electrical grid, you must get permission from the local electrical grid operation can

only be performed by qualified electrical engineer.

Please contact the nearest authorized service center if any maintenance or

repair is needed.Contact your distributor for the information of the nearest

authorized service center. Do NOT repair it by yourself, it may cause injury or

property damage.

Before installing and maintaining the equipment, you should turn the DC

switch OFF to cut off the high voltage DC of the PV array. You can also turn the

switch in the PV combiner box OFF to cut off the high voltage DC. Otherwise,

serious injury may be caused.

Qualified persons

The customer must make sure the operator has the necessary skill and training

to do his/her job.Staff in charge of using and maintaining the equipment must be

skilled,aware and mature for the described tasks and must have the reliability to

correctly interpret what is described in the manual. For safety reason only a

qualified electrician, who has received training and / or has demonstrated skills and

knowledge in construction and in operation of this unit, can install this inverter.

DASS Tech Co., Ltd does not take any responsibility for the property destruction

and personal injury because of any incorrect use.

Installation requirements

Please install inverter according to the following section. Fix the inverter on

an appropriate objects with enough load bearing capacity (such as walls, PV racks

etc.), and ensure that inverter is vertical placed. Choose a place suitable for

installing electrical devices. And assure there is enough fire exit space, convenient

for maintenance. Maintain proper ventilation to ensure enough air cycle to cool the

inverter.

Transport requirements

If you find packing problems that may cause the damage of the inverter, or

find any visible damage, please immediately notice the responsible transportation

company. You can ask solar equipment installation contractor or DASS Tech Co.,

Ltd for help if necessary.

Transport of the equipment, especially by road, must be carried out with by

suitable ways and means for protecting the components (in particular, the electronic

components) from violent shocks, humidity, vibration, etc.

Electric connection

Please comply with all the current electrical regulations about accident

prevention in dealing with the solar invert.

Before the electrical connection, make sure to use opaque

material to cover the PV modules or to disconnect PV array DC

switch. Exposure to the sun, PV array will produce a dangerous

voltage!

Danger

All installation accomplished only by professional electrical

engineer!

Must be trained;

Completely read the manual operation and understand

relevant matter.

Warning

Get permission from the local electrical gird operator,

complete all electrical connections by professional electrical

engineer, then connect inverter to electrical grid.

Attention

It’s forbidden to remove the tamper evident label, or open the

inverter. Otherwise DASS Tech Co., Ltd will not provide warranty

or maintenance!

Note

Operation

Touching the electrical grid or the terminal of the equipment

may lead to electrocution or fire!

Don’t touch the terminal or conductor connected to the

electrical grid.

Pay attention to any instructions or safety documents related to

grid connection.

Danger

Some internal components will be very hot when inverter is

working. Please wear protective gloves!

Attention

Maintenance and repair

DASS 3.0i LV (DSP-123i-ODS) User manual

- 4 -

Before any repair work, turn OFF the AC circuit breaker

between the inverter and electrical grid first, then turn OFF the DC

switch.

After turning OFF the AC circuit breaker and DC switch, wait

for 5 minutes at least before carrying out any maintenance or repair

work.

Danger

Inverter should work again after removing any faults. If you

need any repair work, please contact with the local authorized

service center.

Can’t open the internal components of inverter without

authorized. DASS Tech Co., Ltd does not take any responsibility for

the losses from that.

Attention

EMC / noise level of inverter

Electromagnetic compatibility (EMC) refers to that one electrical equipment

functions in a given electromagnetic environment without any trouble or error, and

impose no unacceptable effect upon the environment. Therefore, EMC represents

the quality characters of an electrical equipment.The inherent noise-immune

character: immunity to internal electrical noise.External noise immunity: immunity

to electromagnetic noise of external system.Noise emission level: influence of

electromagnetic emission upon environment.

Electromagnetic radiation from inverter may be harmful to

health!

Please do not continue to stay around the inverter in less than 20

cm when inverter is working.

Danger

1.2. Symbols and signs

Caution of burn injuries due to hot enclosure!

You can only touch the screen and pressing key of the inverter

while it’s working.

Caution

PV array should be grounded in accordance to the requirements

of the local electrical grid operator!

We suggest that all PV module frames and inverter are reliably

grounded to protect the PV system and personnel security.

Attention

Ensure input DC voltage < Max. DC voltage .Over voltage may

cause permanent damage to inverter or other losses, which will not

be included in warranty!

Signs on the inverter

There are some symbols which are related to security on the inverter. Please

read and understand the content of the symbols, and then start the installation.

There is a residual voltage in the inverter! Before opening the

equipment, operator should wait for five minutes to ensure the

capacitor is discharged completely.

Caution, risk of electric shock.

Caution hot surface.

Comply with the Conformite Europeenne (CE) certification.

Grounding point.

Please read this manual before install DASS 3.0i LV

(DSP-123i-ODS).

This indicates the degree of protection of the equipment

according to IEC standard 70-1 (EN 60529 June 1997).

Positive pole and negative pole of the input voltage (DC).
