Transmission Cables
Connect wiring in series from the Master, with positive terminals connected to-
gether and negative terminals connected together.
Set the last connected Slave as the terminator. Do not set an intermediate Slave
as a terminator.
Total cable length per system: 200 m max.
The size of terminal screw differs for the Master and Slave. Consider the size of
the terminal screws when using solderless terminals.
Master terminal: M3 (optimum tightening torque: 0.5 N
S
m); Slave terminal:
M3.5 (optimum tightening torque: 0.8 N
S
m)
Locate transmission cables away from power cables and high-voltage cables to
eliminate the effects of noise.
Recommended Cables
The G730 Interface Unit can be connected to the G730 Remote Terminal using
the following cable.
Cable: VCTF 0.75 x 2C

The connection method of a Master and Expansion Master to Slaves is shown in
the following diagram.
Connect wiring of each system in series from Master, Expansion Master to Slave
with positive terminals connected together and negative terminals connected to-
gether.
Expansion Master terminals B0 to B2 and B1 to B3 are shorted internally. They
can be used in any combination.
Set the last connected Slave as the terminator. Do not set an intermediate Slave
as a terminator.
Total cable length per system: 200 m max.
The size of terminal screw differs for the Master/Expansion Master and Slave.
Consider the size of the terminal screws when using crimped terminals.
Master/Expansion Master terminal: M3; Slave terminal: M3.5
