DT-NTSC-32 Manual
Users should make sure the 2 ends of grounding wire are well electrically conducted and be
anti-rust.
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
4 AWG (25mm
2
).
Please refer to Article 100 of the NEC for all grounding related items
2.2.4 Frame Grounding
All the machine frames should be connected with protective copper strips. 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 4 AWG (25mm
2
).
2.2.5 Device Grounding
Connecting the device’s grounding rod to the frame's grounding pole with copper wire.
2.3 Wire’s Connection
2.3.1 Power cord connection
The power socket is located on the right of the rear panel, as is the power switch. 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 an independent way, say, share the same ground
with other devices. When the device adopts a united way, the grounding resistance should be
smaller than 1Ω.
Caution: Before connecting power cord to DT-NTSC-32, users should set the power
switch to “OFF”.
