➢
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 25mm

2.5.1
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 25mm

2.5.2
DEVICE GROUNDING
Co
nnecting the device’s grounding rod to frame’s grounding pole with copper
wire.
2.6
WIRE’S CONNECTION
Power Cord Connection:
The power socket is located on the right of rear panel, and the power switch is on the left of
front panel. User can plug one end of the power cord to the socket and insert the other end to
AC power. 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 resist
ance should be smaller than 1Ω.
Caution
: Before connecting power cord to TL-9916 16 in 1 IP QAM Modulator, user should
set the power switch to “OFF”.
