3.4. Wiring Instructions
(1) Connection with the position detector (PLG).
Use twisted pair shielded cables (0.2mm
2
or larger) to connect the FR-A5AP and position detector (PLG).
Cables to terminals 5V and SG should be connected in parallel or be larger in size according to the cable length
table as indicated below.
To protect the cables from noise, run them (at least 10cm) away from any source of noise (e.g. the main circuit
and power supply voltage).
Note: If the cable size is too large to connect the terminals to the terminal block or if the number of cables is
increased due to parallel connection and they cannot be contained in the wiring space, provide a junction terminal
block, for example.
(2) Cable length.
1) Cable length within 30m.
Cable Length
Number of Parallel Cables of 0.2mm
2
Required
Larger-Size Cable
Within 10m At least 2 cables
0.4mm
2
or larger
Within 20m At least 4 cables
0.75mm
2
or larger
Within 30m At least 6 cables
1.25mm
2
or larger
2) Cable length of more than 30m.
Use a power supply slightly higher than 5V (approximately 5.5V) in addition to 6 or more parallel cables of
0.2mm
2
or cables of 1.25mm
2
or more. This allows the cable length to be increased up to 100m. Note that the
voltage applied
across terminals 5V-SG must not exceed 6V.
