Before Installation

Before Installation

This manual contains general and safety
instructions to be observed while install­ing and operating the LG Solar modules.
Please read this manual carefully before
installation. All installation and safety in­structions should be clearly understood
before attempting to install, wire, com­mission, or service the solar module.
Non-adherence can lead to personal
injury and material damages.

This manual is only intended for quali­fied persons and specialist technicians.

This manual is for the monocrystalline
solar modules LG240M1C, LG235M1C,
LG230M1C, the multicrystalline solar
modules LG230P1C, LG225P1C and
LG220P1C, and other power classes.

Solar modules from LG Electronics are
photovoltaic solar modules for convert­ing light into electrical energy. The solar
modules are designed f

or use in photo­voltaic systems. Any other application is
not conventional.

Exemption from Liability

No warranty or liability can be granted
for any damages arising from improper
installation.

Safety

Accident prevention guidelines, rules
and regulations issued by the organisa­tions and authorities concerned apply to
installation, operation and maintenance.
If applicable, observe the national and
regional directives, in particular the fire
protection regulations.

Please also follow the individual safety
regulations for the other components
used in the photovoltaic system.

Electric Voltage Hazard Warning

The following safety instructions and
statutory directives must be observed
and adhered to.

Installation and maintenance may only

be carried out by qualified persons and
only in compliance with the local direc­tives.

Keep children away while installing the

photovoltaic system and solar modules.

There is mortal danger due to electric

shock and arc load.

Contact with electrically live parts of the

solar module such as terminals could
lead to burns, sparks and fatal electric
shocks.

Safety

EN

Observe the special safety directives on

handling direct current and photovoltaic
systems. The solar modules always
generate direct current when exposed
to sunlight. This can lead to life-threat­ening values in just one single solar
module. The solar modules are pro­tected only at the DC switch.

Never disconnect under load. There

may be life-threatening arc loads that
cannot be put out independently.

Do not touch the junction box, cable

ends and plug connections with bare
hands during the installation or in sun­light, regardless of whether the solar
module is connected to the photo­voltaic system or not.

Do not insert any part in the connector

plugs or jacks.

Do not carry out any work in wet weather

to avoid electric shock. Do not use any
wet tools. Do not work on wet terminals
of the solar module either.

Use insulated tools and rubber gloves

recommended for working on electrical
equipment.

Never leave the solar module unse-

cured.

Accident Hazard Warning

The following safety instructions and
statutory directives must be observed
and adhered to.

Installation and maintenance may only

be carried out by qualified persons and
only in compliance with the local direc­tives.

Use suitable safety measures to pre-

vent falls when working high above the
ground. If applicable, observe the cor­responding directives and recommen­dations of the occupational health
agencies or relevant organisations.

Do not work under rainy, snowy or windy

conditions.

While working at heights, be careful to

avoid the danger of objects falling.

Handle broken or damaged solar mod-

ules carefully and with appropriate
safety gear.

Do not touch the glass and rear side of

the solar module with bare hands. Wear
safety gloves to avoid injuries.

The glass surface and module frame

can heat up under the sun’s rays, which
may result in burning of the skin. Use
safety gloves if required.
