dissipation.
zWhen installing the unit, always make the groundconnection first and disconnect it
last.
zDo not block ventilation openings while the system is on, and keep at least 5 cm
distance from ventilation openings and walls or other things which may block the
openings
zNever defeat the ground conductor or operate the equipment in the absence of a
suitably installed ground conductor. Contact the appropriate electrical inspection.
zThe unit/system must be connected to the protection ground before operation
permanently. And the cross-section of protective earthing conductor shall be at
least 4mm2
zThe device applies to TN power systems.

zThe plug-socket combination must be accessible at all times because it serves as
the main disconnecting device.
zTo reduce the risk of fire, use only No. 26 AWG or larger telecommunication line
cord
zNo operation can be done on the device and cables when lightning.
zTo enhance the lightning protection capability of the power supply, a lightning
arrester is recommended at the input end of the power supply.
zTo avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone-network voltage (TNV) circuits.
zFor safety It is not recommended to wear jewelry and watch during operation on
device.
zInstallation, configuration and disassembly must be done only by skillful personnel
according to the documents concerned.

user to the person in charge.
zRemoval or disabling of safety facilities, troubleshooting, and maintenance of the
equipment must be done by qualified specialists only.
All parts of the document must be followed to the full. The document also serves as a
guide to the selection of measuring and test equipment.
3.2 Electricity Safety
3.2.1 High Voltage
Danger:
High voltage power supply offers electric power for equipment operation. Direct contact
or indirect contact (via damp objects) with high voltage and AC mains supply may result
in fatal danger.
zDuring the installation ofAC power supply facility, the local safety regulations must
be followed. The personnel who install the AC facility must be qualified for high
voltage andAC operations.
zConducting articles, such as watch, hand chain, bracelet and ring are prohibited
during the operation.
zWhen water is found in the rack, or the rack is damp, please immediately switch off
the power supply.

H3C VG 20-16/20-32 Voice Gateway Chapter 3 Safety Information
3-4
zWhen operation is performed in a damp environment, make sure that water is kept
off the equipment.
Warning:
Non-standard and improper high voltage operations may result in fire and electric
shock. Therefore, AC cable bridging and wiring through a certain area must follow the
local rules and regulations. The personnel who perform high voltage operations should
be qualified for high voltage and AC operations.
3.2.2 Power Cable
Note:
Installation and removal of live power cable is prohibited strictly. Transient contact
between the core of power cable and conductor may generate electric arc or spark or
electric arc, which may lead to fire or eye injury.
zBefore the power cable is installed or removed, the power switch must be turned
off.
zBefore the power cable is connected, it must be confirmed that the power cable
and label comply with the requirements of the actual installation.
