NOTES
• Use ring-type crimp style terminal for connections to
the power terminal block. (Refer to Fig. 6)
Also, insulate the crimped area by attaching an
insulation sleeve, etc.
If these are not available, see the following section.
(a)Wiring of different thicknesses cannot be connected
to the power terminal block.
(A loose connection could cause abnormal
heating.)
(b)When connecting wire of the same diameter, make
the connection as shown in the figure 7.
• Use an appropriate screwdriver for tightening the
terminal screw.
Using a screwdriver that is too small could damage the
screw head and prevent proper tightening.
• Over tightening the terminal screw could damage the
screw.
Refer to the Table 4 for the terminal screw tightening
torque.
• When fastening the wire, use the included clamp 2)-1 so as not to apply tensile force to the wire connection
and then securely fasten the wire. Also, after wiring is completed, organize the wiring so that the EL.
COMPO. BOX lid does not pop up and then properly replace the EL. COMPO. BOX lid.
Make sure no wires are pinched when replacing the EL. COMPO. BOX lid.
Always use the wire through hole to protect the wires.
• Do not pass the transmission wiring and power supply wiring through the same locations and outside of the
unit keep them separated by at least 50mm.
Not doing so could cause the transmission wiring to pick up electric noise (external noise) and result in a
malfunction or breakdown.
• After the wiring working is complete, use sealer (field supply) to seal closed the wire through hole.
(Entry by small animals, etc., could cause a malfunction.)
