wall hanging equipment.
4.3 Cautions about installation
Avoid severe liberation and mechanical damage during the process of delivering
and installation.
Arrange fiber appropriately, fiber bending radius≥50 mm.
Check voltage and polarity meet with back panel, or it will cause permanent damage
to the equipment.
The installation location should be convenient for personal passing and equipment
movement.
The environment should be dry, clean and ventilated well.
Essential static-protective is needed during the installation and maintenance, ground
the chassis to increase anti-interference capability and prevent lightning strike.
Before use the equipment, independence work ground and protect ground should
provided, make sure it ground well.
