4.5.1 Instructions for wiring
!
DANGER
Completely turn off the all lines of the power supply externally before wiring. Not completely turning off
all power could result in electric shock or damage to the product.
When turning on the power supply or operating the module after wiring, be sure that the module's
terminal covers are correctly attached. Not attaching the terminal cover could result in electric
shock.
!
CAUTION
Be sure to ground of the earth terminal FG and LG. Not doing so could result in electric shock or
operation failure. (Ground resistance: 100
or less)
When wiring in the Motion controller, be sure that it is done correctly by checking the product's rated
voltage and the terminal layout. Connecting a power supply that is different from the rating or
incorrectly wiring the product could result in fire or damage.
External connections shall be crimped or pressure welded with the specified tools, or correctly
soldered. Imperfect connections could result in short circuit, fire, or operation failure.
Tighten the terminal screws within the specified torque range. If the terminal screws are loose, it could result in
short circuit, fire, or operation failure. Tightening the terminal screws too far may cause damages to the screws
and/or the module, resulting in drop, short circuit, or operation failure.
Be sure there are no foreign matters such as sawdust or wiring debris inside the module. Such debris
could cause fire, damage, or operation
failure.
The module has an ingress prevention label on its top to prevent foreign matter, such as wiring
debris, from entering the module during wiring.
Do not remove this label during wiring.
Before starting system operation, be sure to remove this label because of heat dissipation.
This section described instructions for the wiring of the power supply.
(1) Power supply wiring
(a) 100VAC, 200VAC and 24VDC wires should be twisted as dense as possible
respectively. Connect the modules with the shortest distance.
Also, to reduce the voltage drop to the minimum, use the thickest wires
possible.
Use the wires of the following core size for wiring.
Application Recommended core size
100VAC, 200VAC, 24VDC wires 2.0mm
2
or less
I/O equipment 0.75mm
2
(0.75 to 1.5mm
2
usable)
Ground wire 2.0mm
