Operation Safety Measures - Solahart Solahart475DH1 Installation Manual

 Avoid partial shading of PV modules for a long
period of time, otherwise the temperature of the
shaded module may rise due to hot spot effect,
burning the module and causing fire hazard in severe
cases.
 For PV modules used in deserts or windy and sandy
areas, it is recommended to use connector dust caps
before installation or take other measures to prevent
sand and dust from entering the connectors,
otherwise it may cause insertion problems or
electrical safety hazards.

3.2 Operation safety measures

 Avoid package damaging and falling during
transportation and storage. Ensure the packing cases
are well ventilated, water-proof and dry. After the
arrival, carefully open the outer package and prevent
scratches and bumps of PV modules. When stacking
PV modules, strictly
requirements in chapter 4.3.
 Avoid impact or scratches on any part of the PV
module, otherwise the reliability and safety of the
PV module will be affected; standing or walking on
the PV module is prohibited; at the same time, in
order to avoid glass damage, it is forbidden to apply
excessive load or distorted PV modules.
 Do not install or carry PV modules by one person.
It is forbidden to pick up, drag, or move PV modules
by grabbing the junction box (including the box
body, cables, and connectors); when placing a PV
module on a flat surface, it must be operated
carefully and be aware of bumps in the corners.
 When installing or repairing the PV system, do not
5
follow the stacking
wear any metal accessories to avoid the risk of
electric shock; if it is installed far above the ground,
please wear a seat belt.
 When operating PV modules in the sun, please use
insulated tools, and wear rubber gloves and
protective clothing. At the same time, in order to
avoid the risk of arc and electric shock, do not
directly touch the junction box and the end of the
output cable (connector) with bare hands.
 For electrical connection, choose a dry and weak-
light morning or evening; or use opaque materials to
completely cover the surface of the PV modules to
prevent current generation.
 A certain distance between the PV module and the
installation surface should be kept to prevent the
installation surface from touching the junction box.
 When installing on the roof, comply with the fire
protection requirements of the building. It is
recommended to install PV modules on a fireproof
and insulated roof covering, and ensure adequate
ventilation between the PV modules and the
installation surface. In order to ensure the fire rating
on the roof, the minimum distance between the
frame of the PV module and the roof surface is
10cm.
 The connector must be fully mated when wiring. If
the cable is too long, it is recommended to fix the
cable to the rack system with a UV-resistant nylon
cable tie. When fixing the cable to the rack, the
bending radius of the cable should not be less than
48mm.
 Avoid directly exposing cables and connectors to
sunlight. Please use anti-UV cables.
