Put off ornaments, such as ring, necklace, watch and bracelet, before you
operate under live working. When metal articles connect the power to the
ground, short circuit happens and components may be damaged.
Please cut off the direct-current connection when you operate the hull or work
near the power supply.
When the power is on, do not touch the power.
Correctly connect the device and the power socket.
Only professionals are allowed to operate and maintain the device.
Read the installation guide carefully before the system is powered on.
Note:
1) Check potential dangers, such as the humid floor, ungrounded extensible
power line and tatty power line.
2) Install the emergent on-off at the working room for turning off the power
when trouble happens.
3) Plug off the power line before installing or uninstalling the machine box or
working beside the power.
4) Do not work alone if potential dangers exist.
5) Cut off the power before checkout.
6) If trouble happens, take the following measures:
A. Cut off the system’s power.
B. Alarm.
C. Take proper measures to help persons who are hit by the disaster.
Artificial respiration is needed if necessary.
D. Seek for medical help, or judge the loss and seek for available help.
2.2.4 Electrostatic Discharge Damage Prevention
Electrostatic discharge may damage devices and circuits. Improper treatment may cause
the switch to malfunction completely or discontinuously.
Move or locate the devices according to the measures of electrostatic discharge
prevention, ensuring the machine box connects the ground. Another measure is to wear the
static-proof hand ring. If there is no hand ring, use the metal clip with the metal cable to clip the
unpainted metal part of the machine box. In this case, the static is discharged to the ground
through the metal cable of the clip. You can also discharge the static to the ground through
your body.
2.3 Requirements for Common Locations
This part describes the requirements for the installation locations.
2.3.1 Environment
8/24 switch adopts the wall-mounted installation mode. The switch has no fan, so an
environment with good ventilation is needed for the heat cooling of the switch.
For location planning and device locating, refer to section 2.3.2 “Location Configuration
Prevention”.
