2.2 Installation Safety
2.2.1 Wear protective head gear, insulating gloves, safety shoes, and insulated tools when installing the modules.
2.2.2 Do not install the modules in rain, snow, or otherwise wet or windy conditions.
2.2.3 Completely cover the PV module surface with an opaque material during PV module installation and wiring to prevent
accidental charge buildup.
2.2.4 Plug in connectors tightly when working on wiring.
2.2.5 Due to the risk of electrical shock, do not perform any work if the terminals of PV module are wet.
2.2.6 Do not touch the terminal box and the end of output cables (connectors) with bare hands.
2.2.7 Do not unplug the connector under load.
2.2.8 Do not work alone.
2.2.9 Wear a safety belt if working far above the ground.
2.2.10 Do not wear metallic jewelry, which can cause electric shock, while installing or troubleshooting the PV system.
2.2.11 Follow the safety regulations for any and all other system components, including wires, connectors, charging
regulators, batteries, inverters, etc.
2.2.12 Do not expose wires to direct sunlight. Use UV-resistant cable.
2.2.13 Do not damage the surrounding PV modules or mounting structure when replacing a PV module.
2.2.14 Do not change any PV module components (diode, junction box, plug connectors, etc.).
2.2.15 Maximum reverse current is 20.25A for module with 6 inch cells. Application of the blocking diode and fuse in the
combiner box are recommended for reverse current protection when more than two strings are connected in parallel.
2.2.16 A certain gap is maintained between the PV module and the mounting surface to prevent the mounting surface
touching the junction box.
2.2.17 Standing on the solar PV module is forbidden and also prohibit installation tools or other objects hitting surface of the
solar PV module.
2.2.18 The solar modules are recommended to be installed over a reproof and insulating roof covering when installed on a
roof.
2.2.19 PV cable connection cannot be too tight, it is recommended that the connector and the backsheet have a certain gap.
2.2.20 Region for sand blown, in order to avoid the sand into the connector, we suggest to short circuit module connectors
before installation;If into the grains of sand, may cause internal live parts wear and tear, so there are some electrical safety
hidden trouble.
