(Spain, Eiffage Turroneros)
Installation Guide
Do not connect or disconnect power cables with power on. Transient contact between the core
of the power cable and the conductor will generate electric arcs or sparks, which may cause
fire or personal injury.

Before making electrical connections, switch off the disconnector on the upstream device
to cut off the power supply if people may contact energized components.
Before connecting a power cable, check that the label on the power cable is correct.
If the equipment has multiple inputs, disconnect all the inputs before operating the
equipment.
When routing cables, ensure that a distance of at least 30 mm exists between the cables
and heat-generating components or areas. This prevents damage to the insulation layer of
the cables.
Bind cables of the same type together. When routing cables of different types, ensure that
they are at least 30 mm away from each other.
Ensure that the cables used in a grid-tied PV power system are properly connected and
insulated and meet specifications.
Ensure that the equipment is installed in a well ventilated environment.
To prevent fire due to high temperature, ensure that the ventilation vents or heat
dissipation system are not blocked when the equipment is running.
Do not expose the equipment to flammable or explosive gas or smoke. Do not perform
any operation on the equipment in such environments.
Only trained and qualified personnel should perform hoisting operations.
Check that hoisting tools are available and in good condition.
Before hoisting objects, ensure that hoisting tools are firmly secured onto a load-bearing
object or wall.
Ensure that the angle formed by two hoisting cables is no more than 90 degrees, as
shown in the following figure.
