BASIC SAFETY INFORMATION

HYD 5~20KTL-3PH 7

2 Basic safety information

NOTE

If you have any questions or problems after reading

the following information, please contact SOFAR

This chapter details the safety information pertaining to the

installation and operation of the device.

2.1 Safety information

Read and understand the instructions within this manual and

familiarise yourself with the relevant safety symbols in this

chapter before beginning with the installation of the device and

eliminating any faults.

Before connecting to the power grid, you must obtain official

authorisation from the local power grid operator in accordance

with the corresponding national and state requirements.

Furthermore, operation may only be carried out by qualified

electricians.

Please contact the nearest authorised service centre if any

maintenance or repairs are required. Please contact your dealer

to obtain information about your nearest authorised service

centre. Do NOT carry out repairs on the device yourself; this may

lead to injury or property damage.

Before installing the device or carrying out maintenance on it,

you must open the DC switch in order to interrupt the DC

voltage of the PV generator. You can also switch off the DC

voltage by opening the DC switch in the generation junction

box. Not doing this may result in serious injury.

2.1.1 Qualified personnel

Personnel tasked with the operation and maintenance of the

device must have the qualifications, competence and

experience required to perform the described tasks, while also

being capable of fully understanding all instructions contained

within the manual. For safety reasons, this inverter may only be

installed by a qualified electrician who:

BASIC SAFETY INFORMATION

8HYD 5~20KTL-3PH

-has received training on occupational safety, as well as the

installation and commissioning of electrical systems

-is familiar with the local laws, standards and regulations of

the grid operator.

SOFAR assumes no responsibility for the destruction of property

or any injuries to personnel caused by improper usage.

2.1.2 Installation requirements

Please install the inverter according to the information

contained in the following section. Mount the inverter to a

suitable object with a sufficient load-bearing capacity (e.g. walls,

PV frames etc.) and ensure that the inverter is upright. Choose a

suitable place for the installation of electrical devices. Ensure

that there is sufficient space for an emergency exit which is

suitable for maintenance. Ensure sufficient ventilation in order

to guarantee an air circulation for the cooling of the inverter.

2.1.3 Transport requirements

The factory packaging is specifically designed to prevent

transport damage, i.e. violent shocks, moisture and vibrations.

However, the device must not be installed if it is visibly

damaged. In this case, notify the responsible transport company

immediately.

2.1.4 Labelling on the device

The labels must NOT be concealed by items and foreign objects

(rags, boxes, devices, etc.); they must be regularly cleaned and

kept clearly visible at all times.

Observe all applicable electrical regulations when working with

the Solar inverter.

BASIC SAFETY INFORMATION

HYD 5~20KTL-3PH 9

DANGER

Dangerous DC voltage

Before establishing the electrical connection, cover the

PV modules using opaque material or disconnect the

PV generator from the inverter. Solar radiation will

cause dangerous voltage to be generated by the PV

generator!

DANGER

Danger through electric shock!

All installations and electrical connections may only be

carried out by trained electricians!

IMPORTANT

Authorisation for grid feed-in

Obtain authorisation from the local power grid

operator before connecting the inverter to the public

power grid.

NOTE

Voiding of guarantee

Do not open the inverter or remove any of the labels.

Otherwise, SOFAR shall assume no guarantee.

2.1.5 Operation

DANGER

Electric shock

Contact with the electrical grid or the device's

terminals may result in an electric shock or fire!

Do not touch the terminal or the conductor which is

connected to the electrical grid.

Follow all instructions and observe all safety

documents that refer to the grid connection.

BASIC SAFETY INFORMATION

10 HYD 5~20KTL-3PH

CAUTION

Burning due to hot housing

While the inverter is being operated, several internal

components will become very hot.

Please wear protective gloves!

Keep children away from the device!

2.1.6 Repair and maintenance

DANGER

Dangerous voltage!

Before carrying out any repair work, first switch off the

AC circuit breaker between the inverter and power

grid, and then the DC switch.

After switching off the AC circuit breaker and the DC

switch, wait a minimum of 5 minutes before starting

any maintenance or repair work.

IMPORTANT

Unauthorised repairs!

Following the elimination of any faults, the inverter

should be fully functional once more. Should any

repairs be required, please contact a local authorised

service centre.

The internal components of the inverter must NOT be

opened without the relevant authorisation. Shenzhen

SOFARSOLAR Co., Ltd. assumes no responsibility for

any resulting losses or defects.
