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 switch, fuse, power supply socket is just beside ,whose order goes like this,
power switch is on the left ,power supply socket is on the right and the fuse is just
between them.
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 TQM1616 16 in 1 Mux-Scrambling QAM
Modulator, user should set the power switch to “OFF”.
2.4 Signal Cable Connection
