WARNING
Use ring terminals and tighten the terminal screws to the specifi ed torques, other-
wise, abnormal overheating may be produced and possibly cause heavy damage
inside the unit.
Be sure fi ll the holes of power supply cable and transmission cable with putty (fi eld
supply).
If small animals such as insects enter the electrical component box, a short circuit
may be caused.
Tightening torque
M3 screw 0.5 to 0.6 N·m (5 to 6 kgf·cm)

Caution when wiring cable
1) Use crimp-type terminals with insulating sleeves as shown in the fi gure to con-
nect to the terminal block.
2) Securely clamp the crimp-type terminals to the cables using an appropriate tool
so that the cables do not come loose.
3) Use the specifi ed cables, connect them securely, and fasten them so that there
is no stress placed on the terminals.
4) Use an appropriate screwdriver to tighten the terminal screws. Do not use a
screwdriver that is too small, otherwise, the screw heads may be damaged and
prevent the screws from being properly tightened.
5) Do not tighten the terminal screws too much, otherwise, the screws may break.
6) See the table for the terminal screw tightening torques.

Sealing transmission cable
Connect both ends of the sealed wires of the transmission cable to the earth terminal
of the equipment or to the earth screw near the terminal.
Be very careful that the screws are not overly tightened as the wires may snap and
the terminal may be damaged.
Wind with insulation tape to
prevent short circuit
Use one side of the Connect both ends of sealed
twisted-pair cable cable to earth.
Be sure to use one side of a twisted-pair cable when using transmission cable with 2
sets of twisted-pair cables.
