(d) Power line connecting to the external power supply terminal (compliant
with I/O power port of CE standard) should be 30m (98.43 ft.) or less.
Power line connecting to module power supply terminal (compliant with
main power port of CE standard) should be 10m (32.81 ft.) or less.
(e) A power line connecting to the analog input of the following modules
should be 30cm or less.
• AJ65BT-64RD3
• AJ65BT-64RD4
• AJ65BT-68TD
(7) Measures against static electricity
When using an insulation displacement connector without connector cover,
a connected cable for the connector is thin in applicable wire size and
coating. Therefore, note that the module may cause an electric discharge
failure.
As measures against the failure, using pressure-displacement type
connector whose applicable wire size is thick or soldering type connector is
recommended.

3.1.4 Power supply module

The precautions required for each power supply module are described below.
Always observe the items noted as precautions.
Model
A1S61PN, A1S62PN
A1S63P 10
1: If sufficient filter circuitry is built into the 24 VDC external power supply
module, the noise generated by A1S63P will be absorbed by that filter
circuit, so a line filter may not be required.
Filtering circuitry of version F or later of A1S63P is improved so that a
external line filter is not required.
2: To ensure the compliance with CE (EN6111-21/A11), make sure to short
the LG and FG terminals using a wire of 6 to 7cm.
