Electrical Installation
General Wiring
•LG Electronics recommends that all wiring be
double insulated with a minimum rating of 90°C
(194°F).
•All wiring should use a flexible copper (Cu)
conductor.
•The minimum size should be determined by the
applicable codes.
•We recommend a size not smaller than 4mm
Earth Grounding
•The solar modules from LG Electronics meet the
conditions of safety class II. Therefore grounding is
not
mandatory.
However
recommended. Also equipotential bonding must be
realized. The national directives must be respected.
•Specific
information
dimensions and location of grounding holes is
provided in 'Product Specifications'.
•One M4 stainless steel bolt, one nut, one spring
washer, two flat washers, one cup washer, one
star
washer
and
12
recommended per solar module.
•There is an earth hole in the center of the module
frame. Using this hole, an earth conductor and the
solar module frame may be recommended to
connected and earthed as the below drawing.
• To prevent electric shock and fire, a protective
ground must be done on the frames of solar
modules and arrays although the solar modules
from LG meet the conditions of safety class Ⅱ.
The national directives must be respected.

Module Mounting
• The LG Electronics' (LGE) Limited Warranty for
solar modules is contingent upon modules being
mounted in accordance with the requirements
described in this section.
• The solar modules are in Application Class A and
have the Safety Class II. Therefore they can be
operated in systems with 120 V DC and higher.
General access is not restricted.
Site Consideration
LGE solar modules should be mounted in a loca-
tion that meets the following requirements.
Operating Temperature
is
• Maximum Operating Temperature: +90°C (194°F)
• Minimum Operating Temperature: -40°C (-40°F)
Excluded Operating Environments
• The solar modules from LG Electronics can be
operated in a location where they could come in
contact with salt water or ammonia, if they have
been tested successfully for these operating
conditions. Please see related certificates. Please
get a release from LG Electronics for increased
conditions.
