Step 4 : Confirm how to install Signal Amplifier
„ z
When Signal Amplifier is installed, network is divided into two network segments.
In a network segment (NS) divided by a Signal Amplifier, it has to keep the following facts.
1)Total transmission line length: MAX 500 m
AB+BC+BD < 500 m (Fig. 2)
2)The total number of units* : MAX 64
3)The number of terminal resistor : 1
4)The total number of control units : 2
Step 5 : Confirm how to wire transmission line
„ z
Confirm how to connect transmission line between indoor units.
Arrange so that there is one terminal resistor for each network segment. ●
Always take a ground from both ends of transmission line. ●
Step 6 : Confirm transmission wiring system
„ z
Check your transmission wiring system if the transmission wiring system is ensured wiring
rule.
