6.6. Wiring procedure
• Remove the cover of the electrical compartment and follow the terminal plate to connect
the electric cables to the terminal.
• After connecting the cables, secure them with the cable ties.
• Connect the cables without applying excessive tension.

* Tighten the cable tie firmly so that pulling force does not propagate to the terminal con-
nection even if force of 100 N is applied to the cable.
6.6.2 Connecting cables to the terminals
WARNING
Use ring terminals and tighten the terminal screws to the specified torques, otherwise,
abnormal overheating may be produced and possibly cause heavy damage inside the
unit.
Be sure fill the holes of power supply cable and transmission cable with putty (Locally
purchased).
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)
M8 screw 5.0 to 7.0 N·m (50 to 70 kgf·cm)
How to connect wiring to the terminal
Caution when wiring cable
(1) Use ring terminals with insulating sleeves as shown in the figure to connect to the
terminal block.
(2) Securely clamp the ring terminals to the cables using an appropriate tool so that
the cables do not come loose.
(3) Use the specified 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 screw-
driver 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 below for the terminal screw tightening torques.

6.6.4 Connecting the transmission cable
Shielding the transmission cable
Connect both ends of the shielded
wire of the transmission cable to
the earth (ground) terminal of the
equipment or to the earth (ground)
screw near the terminal.
Be sure to use one side of a
twisted-pair cable when using
transmission cable with 2 sets of
twisted-pair cables.
Wind with insulation tape to prevent short circuit
Use one side

pair cable
Connect both ends of shielded
wire to earth (Ground).
