10 Electrical Installation
A - Loosen the screws and put the
wire into the opening on the
terminal block.
B - Wire with a crimp ferrule attached,
or unsoldered wire with the core
wires lightly twisted
C - Pull back the shielding and lightly
twist the end with your fingers to
keep the ends from fraying.
Figure 10.14 Wiring Procedure for the Control Circuit
Note:
• It is easier to wire TB1-1 first, then TB1-2, then TB1-3.
• Do not solder the core wire. Soldered wiring connections can become loose and cause the drive to
malfunction.
• Tighten all terminal screws to the correct tightening torque. Connections that are too loose or too tight
can cause incorrect operation and damage to the drive. Incorrect connections can also cause death
or serious injury from fire.
• Refer to
Figure 10.15
• Prepare the wire ends of shielded twisted-pair wires as shown in
reference from an external frequency setting potentiometer to set the frequency. Connect the shield
to the ground terminal

D - When you do not use crimp
ferrules, remove approximately 5.5
mm (0.21 in) of the covering at the
end of the wire.
E - Blade width of 2.5 mm (0.1 in) or
less
F - Blade thickness of 0.4 mm (0.01 in)
or less
