■1): Terminal assignment is shown in
■2): These terminals should be connected with wire using crimp-type terminal.
The available crimp-type terminal is shown in figure 3.5.

Screw
(Tighten torque)
Fuse or Circuit Breaker shall be installed in power supply line.
Do not connect to main circuit of breaker directly.
1. This terminal has to be grounded to the protective ground
conductor by a thick wire of low impedance (*ground
resistance: 100 ohm or less).
2. Connect the FG terminal of each BIF-MD independently. If
not use ground independently, use common ground according
M3
to the figure 3.3.
(0.5 to 0.6N.m)
For Modbus cable.
In case of two wires cable, no need to use.
There is a terminate register in this device.
In case of the ends of network, connect two Ter. terminals by
short wire as shown in figure 3.4.
