8.1.4 Power supply module
The precautions required for each power supply module are described below. Always
observe the items noted as precautions.
A1S61PN, A1S62PN
A1S63P
A1SJHCPU (S8)
(h) To supply the module power supply terminal of the AJ65BTB2-16R/16DR,
AJ65SBTB2N-8A/8R/8S/16A/16R/16S with power using the AC/DC power
supply, follow as shown below.
• Install the AC/DC power supply in the control panel where the module is
installed.
• Use a CE-marked AC/DC power supply and ground the FG terminals. (The
AC/DC power supply used for the tests conducted by Mitsubishi: TDK-Lambda
Corporation: DLP-120-24-1)
• For the cable connected to the AC input terminal and DC output terminals of
the AC/DC power supply, attach a ferrite core. Twist the cable around the
ferrite core by one as shown below. (Ferrite core used for the tests conducted
by Mitsubishi: NEC TOKIN Corporation: ESD-SR-250)
CC-Link/LT module
To supply the CL2DA2-B and CL2AD4-B with 24VDC power using the CL1PAD1,
keep the length of the power cable from the CL1PAD1 to the 24VDC power supply to
30m or less.
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.
Model
*1
*1 Filter attachment to the power cable is not required for the A1S63P product with the version
(F) and later. However, use the 24VDC panel power equipment that conforms to the CE.
*2 Make sure to attach two ferrite cores to the power line.
Attach them as close to the power supply module as possible.
Use a ferrite core whose damping characteristic is equivalent to that of the RFC-H13
produced by KITAGAWA INDUSTRIES CO., LTD.
Make sure to short the LG and FG terminals with a cable of 6 to 7cm and
ground the cable.
Use a CE-compliant 24VDC power supply in the control panel.
Make sure to short and ground the LG and FG terminals.
