Chapter 4 Installation, Wiring and Maintenance of the Product
[3] Precautions for FG terminal wiring
(1) Wiring
Use the thickest wires (Up to 1.31mm
2
) possible to reduce the voltage drop
to the minimum for the FG cable of the Simple Motion module.
Use the wires of the following core size and crimping terminal for wiring.
(a) Ground wire
Application
Recommended core size
AWG
(Note-1)
Ground wire
0.517 to 1.31 mm
2
AWG20 to AWG16
(b) Crimping terminal
Applicable name
Recommended core size
AWG
(Note-1)
RAV1.25-3
0.517 to 1.31 mm
2
AWG20 to AWG16
(Note-1): AWG stands for "American Wire Gauge". AWG is a unit of the thickness of conducting wire.
(2) Grounding
For grounding, follow the steps (a) to (c) shown below.
(a) Use a dedicated grounding wire as far as possible.
(Ground resistance: 100
or less)
(b) When a dedicated grounding cannot be performed, use 2) Common
grounding shown below.

Grounding
1) Independent grounding.....Best
Grounding
2) Common grounding.....Good
3) Joint grounding.....Not allowed
(c) For grounding a cable, use the cable of AWG20 to AWG16 (0.517 to
1.31 mm
2
).
Position the ground-contact point as nearly to the Simple Motion
module as possible, and reduce the length of the grounding cable as
much as possible.
