2 Preparation before Installation
2.1 Safety Suggestions
To prevent device damage and bodily injury, please read carefully the safety recommendations described in this
chapter.
The recommendations do not cover all possible hazardous situations.
2.1.1 General Suggestions
Ensure that the device is installed indoors or in semi-open space.
The device is designed and evaluated just for operation at altitude below 5,000m. Therefore, the device can be
safely used at altitude below 5,000m. And there may be potential risks at altitude beyond 5,000m.
Keep the chassis clean and free of dusts.
Do not place the equipment in a walking area.
Do not wear loose clothes or any other things that may be caught by the chassis during installation and
maintenance.
Turn off the power and disconnect all cables before removing the chassis.
2.1.2 Safety Precautions for Removal
Avoid moving the equipment frequently.
Turn off all power supplies and unplug all power cables before you remove the equipment.
Keep balance when moving the equipment, and avoid injuring your leg and feet or spraining your waist.
2.1.3 Electrical Safety
Please observe local regulations and specifications when performing electrical operations. Relevant operators
must be qualified.
Please carefully check for any potential danger in the working area, for example, ungrounded power supply,
unreliable grounding of the power supply and damp/wet ground or floor.
Find out the location of the emergency power supply switch in the room before installation. First cut off the power
supply in case of an accident.
Avoid hot-line work by a single operator.
Be sure to make a careful check before you shut down the power supply.
Do not place the equipment in a damp/wet location. Do not let any liquid enter the chassis
