1. Precautions for Safety

Precautions for safety aim for safe and correct operation of the products by preventing

accidents or hazards in advance, so you must follow them at all times.

In order to properly and safely use the functions of DSP inverter series, read the manual

carefully.

After reading the operation and installation manual, please store it in a place where all users

can easily find and read it.

DSP series inverter is a grid-connected PV inverter that transforms direct current of PV

generator into alternate current and connects to the system.

※The DSP series inverter must only be operated with PV arrays of protection class II in accordance

with IEC 61730, application class A. DSP series inverter shouldn’t be connected to any energy source

other than PV module

Deadly risk due to the high voltage of the inverter

When the photovoltaic generator array is exposed to the light, dangerous DC voltage on the

DC conductor or the conductive parts of the inverter can be generated. If you are contact on

the DC conductor or the conductive parts, you may be deadly shocked by electricity.

Use caution not to be contacted on the DC conductor.

Use caution not to be contacted on the live conductive parts of the inverter.

Separate the inverter from all power sources before you carry out any work on the inverter.

1.1 Symbols Used in the Manual

The meaning of the symbols used in the manual is as follows:

Danger indicates a hazardous situation which, if not avoided, will result in death or serious injury

Warning indicates a hazardous situation which, if not avoided, can result in death or serious injury

Caution indicates a hazardous situation which, if not avoided, can result in minor or moderate injury

1.2 Symbols Used in the Inverter

The meaning of the symbols used in the inverter is as follows:

Symbol

Description

Do not lift up or move the product alone.

Keep the connection requirements of secondary protective conductor.

Refer to Ground Connection in page 26.

The product can be heated during the inverter’s operation. Do not touch the

inverter enclosure during operation.

Before carrying out any work, you should wait for the product cooled down

completely.

Wear safety gloves and personal protective equipment.

The product is worked on a high pressure. All works related with the inverter

must be performed by a professional electric engineer.

The capacitor of the inverter may charged with very high voltage.

Se[arate the inverter from all power sources and wait for 10 minutes or longer

before your work in order for the capacitor to be discharged.

Follow the local electronic waste regulations when disposing the inverter.

Transport the product by 2 persons or more or use dedicated equipment.

Follow the instructions in the manual provided with the inverter.

This product is complied with the corresponding CE requirements.

1.3 Precautions while Operating

Do not operate the product when the front cover is opened.

It can cause electric shock as the high-voltage terminals or live parts can be exposed.

Do not operate the switch with wet hands.

It can cause electric shock.

Do not open the cover when power is already on or during operation.

It can cause electric shock.

Even if power is not on, do not open the front cover except for regular inspection time.

Even under off-power, voltage can be charged in the internal capacitor of the inverter, which can

cause electric shock.

Check if the DC voltage of the inverter is discharged by using a measurement tool such as

volt-ohm-milliampere (VOM) after 10 min or longer from power off when wiring work or

regular inspection is performed.

Since high voltage can be charged in the internal capacitor of the inverter, it can cause

electric shock.

Do not use the product if the sheath of the cable is damaged.

It can cause electric shock.

Do not place a heavy object that gives excessive stress on the cable while using.

It can cause electric shock due to the damage on the sheath of the cable.

Do not supply power even if the installation is complete when part of the inverter is

damaged.

It can cause electric shock.

Do not install the product near any flammable materials.

If the product is installed with flammable materials or attached near flammable substance, it can

cause a fire.

Disconnect the input power (solar cells) and output power (AC system power) in the inverter

during inverter failure.

If the power is not disconnected, it can cause a fire due to the secondary accident.

Do not touch the front or upper surface of the inverter enclosure during inverter operation.

The front or upper surface of the enclosure can be hot, which can cause a burn.

Do not touch the inverter while power is connected or within 30 min after power is

disconnected.

Since the product is on a high-temperature, it can cause a burn when the product is contacted

with human body.

Do not supply power even if the installation is complete when the inverter is damaged.

It can cause electric shock and additional part damage.

Do not have foreign substances such as screws, metal parts, water or oil get into the inside of

the inverter.

It can cause a fire.

Keep the distance of at least 30 cm from the inverter.

It can risk health due to the emission effect.

2. Product Overview

2.1 Basics

If the inverter is operated incorrectly, it can prevent normal operation or reduce a lifespan of the

product. In the worst case, the inverter can be broken or incur fatal damage to human bodies. Therefore,

please read carefully and understand thoroughly the operation and installation manual prior to the use.

2.2 Appearance of the Product

2.3 Verification of the Product

Please check the name plate at the side of the main product body whether inverter type and

rated output are matched with the ordered product details once the inverter is taken out of the

packaging box. In addition, check whether there is any damage during transportation.

Inverter TYPE

Accessories/tools

- Please contact the office if there are some missing accessories such as the operation and

installation manual, fixed bracket, bracket fixing bolts and hexagon

wrench or if the product is damaged.

- Depending on the operation field, necessary tools can be different and should be prepared

well. (e.g: Multi-tester to check voltage and wiring, power tools to install fixed brackets etc.)
