2.1 Safety Precautions
Note
To avoid personal injury and device damage, carefully read the safety precautions before installation.
The following safety precautions may not cover all possible dangers.
2.1.1 General Safety
Install the device in a standard 19-inch cabinet.
Do not place the device in a wet position, and keep the device away from liquid. Keep the chassis clean and
dust-free.
Install the device in a position far away from heat sources.
Ensure that the cabinet and power distribution system are properly grounded.
Do not place the device in walking areas.
During installation and maintenance, do not wear loose clothes, ornaments, or any other things that may be
hooked by the chassis.
Keep tools and components away from walking areas.
2.1.2 Transfer Safety
Do not frequently move devices.
Cut off all power supplies and unplug all power cords before moving or transferring the device.
The device should be moved by at least two persons. Keep balance and prevent personal injuries when
moving the device.
2.1.3 Electrical Safety
Warning
Any non-standard and inaccurate operation can cause an accident such as fire or electric shock, thus
causing severe damages to human bodies and the device.
Direct or indirect touch on high-voltage and mains supply through a wet object can bring a fatal danger.
Observe local regulations and specifications when performing electrical operations. The operators must be
qualified.
Carefully check any potential danger in the work area, such as ungrounded power supply, unreliable power
grounding, and wet floor.
Before installing the device, find out the location of the emergency power switch in the room. First cut off the
power supply in the case of an accident.
Make a careful check before you cut off the power supply.
