2.2.3 Grounding Requirement
All function modules‟ good grounding designs are the basis of reliability and stability of
devices. Also, they are the most important guarantee of lightning arresting and interference
rejection. Therefore, the system must follow this rule.
Coaxial cable‟s outer conductor and isolation layer should keep proper electric conducting
with the metal housing of device.
Grounding conductor must adopt copper conductor in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.
Users should make sure the 2 ends of grounding wire well electric conducted and be
antirust.
It is prohibited to use any other device as part of grounding electric circuit
The area of the conduction between grounding wire and device‟s frame should be no less
than 25mm2.
NDS3208 8 in 1 MPEG-2 Encoder User’s Manual
7 / 29
2.2.4 Frame Grounding
All the machine frames should be connected with protective copper strip. The grounding wire
should be as short as possible and avoid circling. The area of the conduction between
grounding wire and grounding strip should be no less than 25mm2.
2.2.5 Device Grounding
Connecting the device‟s grounding rod to frame‟s grounding pole with copper wire.
2.3 Wire’s Connection
The grounding wire conductive screw is located at the right end of rear panel, and the power

Connecting Power Cord
User can insert one end into power supply socket, while insert the other end to AC power.
Connecting Grounding Wire
When the device solely connects to protective ground, it should adopt independent way,
say, share the same ground with other devices. When the device adopts united way, the
grounding resistance should be smaller than 1Ω.
Caution:
Before connecting power cord to NDS3208 8 in 1 MPEG-2 Encoder, user should
set the power switch to “OFF”.
