8 Installation Notice: Grounding

For the better transmitting quality, all the devices must ground properly.

Using the power cord of three strands in order to ensure all devices’

grounds are connected together through the power cord. Get together

the whole grounds and connect to earth. Make sure the grounding

resistance is less than 3Ω in order to avoid the natural short with ground

directly; besides, avoid the interference. We suggest you use AC

constant voltage regulator or pure power. All the outlets have to be fixed

by screws and make sure they all connect well. Please refer to the

Figure (5).

Figure (5): Power distribution and grounding

217

PC

PC 1

PC 3 PC 4

PC 2

218

Attention:

1. The ground in the classroom has to connect to earth independently. It

is not allowed using the ground from power distribution room. Be ware;

avoid any type of touch between natural and ground in anywhere.

Normally, use a steel nail and copper plate to be the grounding material

and the electricity has to be grounded two meters deep. Make sure the

grounding resistance is less than 3Ω. Grounding improperly will cause

interference and worsen the qualities of video and audio.

2. Fire and natural’s outlet must design toward the same direction.

Always keep them on the fixed position. For example, if fire’s outlet is on

the left side, always keep it on the left side. Do not change it at all. If the

fire and natural do not design toward the same direction, it will cause

black shaking on the screen while broadcasting.

3. Demands on Phase

Normally, all computers have to connect to the same phase power while

working on the multimedia network system in order to get a better

efficiency. But if they can’t work on the same phrase power, make sure

each outlet has to meet step1 and step2 mentioned above.

Key points of power checking (Checking by multi-meter)

1. Ground check

a. Make sure the power center outlet is working and interflowing. If you

use multi-outlet, make sure the copper slice inside the outlet is

unloosened.

b. Turn off the main power and AVR

219

c. Turn on the multi-meter and change to “Ω” function on rotary switch.

d. Use two probes to plug in different ground outlet. (See the position C

at Figure (6))

e. If the number checked from multi-meter is zero, means the power is

grounded.

f. Do the step D and E repeatedly until you finish all the outlet check.

g. After check the outlets to be all grounded, check the main power in

the classroom does be grounded

2. Phase check

a. Turn on the main power and AVR. Turn on the multi-meter and

change to “voltage” function on rotary switch (at least AC 250V).

b. Use the two probes to plug in the A position of different outlets then

will get a VA (voltage).

c. Does the step again then will get a VB (voltage)?

Should be 0 voltage V

Fig. 6

（Outlet1）（Outlet2）

220

d. Take the 110V for example, if the VA equals zero and VB also equals

zero that means the two outlets have been connected correctly. But if VA

and VB equal 110V that means fire wire and natural wire are connecting

inversely. If VA equals zero and VB equals 220 or vice versa that means

the two outlets are in different phases.

e. Repeat the step b, c and d until finish all the outlets.

See the chart (7)

f. Please check in sequence. Over two rows, you can use extended

power cord to narrow the distance between two rows. The checking

sequence, please refer to chart (8).

Chart (7)

Should be 0VV A
