The grounding conductor should be copper in order to reduce high frequency impedance,
and the grounding wire should be as thick and short as possible.
Users should make sure both ends of the grounding wire are good conductors and rust-
resistant.
Users should not use any other device as part of grounding electric circuit.
The area of conduction between the grounding wire and device’s frame should be no less
than 25 mm

Frame Grounding
All machine frames should be connected with protective copper strips. The grounding wire should
be as short as possible and avoid circling. The area of conduction between grounding wire and
grounding strip should be no less than 25 mm

2.2.5
Device Grounding
Connect the device’s grounding rod to the frame’s grounding pole with copper wire.
2.3
Wire Connection
The grounding wire conductive screw is located at the right end of the rear panel, and the power
switch, fuse, and power supply socket are right next to that. The order is this: the power switch
is on the left, the power supply socket is on the right, and the fuse is between them.
Connecting Power Cord
Insert one end into the power supply socket, and insert the other end to an AC power source.
Connecting Grounding Wire
When the device is independently connected 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 a power cord to the EC2200 SD Encoder, users should set the power switch
to “OFF.”
