During the installation process, for the safety of operator as well as this voip gateway
equipment, please implement the following principles:
Cut off 220V AC or 48V power supply before electrical installation;
Read all notes and warning labels on package and equipment before you open any
component;
Inspect the ground wire connection is right or not, and operate if the connection is
correct. cut off power supply, connect equipment power line, and test the resistance between
cabinet protection ground and shell of the product by multimeter. If the result is 0 ohm, the
ground wire has been connected to the product.If the testing condition is not ready, please
guarantee the power socket has three-input, not 2 line in the use of 220V AC);
Pay attention to electrostatic protection: as air is dry, human body often carries static
electricity, which will cause the breakdown of semiconductor devices. So anti-static bracelets
must be worn during installation. Touch grounding objects (such as heating etc.) is also an
effective way to eliminate static electricity. In order to keep the safety of the personnel, the
resistance of anti-static bracelets which connect hand must be tested, and the result should
be in the range of 1M-10M Ohms.

Signal transmission distance is determined by signal types, transmission media as well
as signal rate.Therefore the limitation of the transmission distance should be considered
during product connection.
Please read this document carefully before installation.
Only specially trained personnel can replace the internal cards
in this gateway.
