(5) External power supply
Use a reinforced or double insulated CE-marked external power supply, and ground the FG terminal.
(External power supply used for the tests conducted by Mitsubishi: DLP-120-24-1 (manufactured by TDK-
Lambda Corporation), PS5R-SF24 (manufactured by IDEC Corporation))
(6) Power supply modules
• Ground the LG and FG terminals after short-circuiting them.
• Use a CE-marked external power supply with a reinforced insulation or a double insulation to supply 24VDC
(7) I/O modules
• Install a DC power supply and an I/O module inside the same control panel.
• Use a shielded cable for the DC power when it is extended out of the control panel.
• Keep each DC power cable length to 30m or less.
• Take a surge protective measure, such as installing a surge suppressor, if the relay switches five times or
(8) High-speed counter modules
• Install a DC power supply and a high-speed counter module inside the same control panel.
• Use a shielded cable for the DC power when it is extended out of the control panel.
• Keep the length of cables connected to external devices to 30m or less.
(9) Positioning modules
Install a DC power supply and a positioning module inside the same control panel.
(10)Temperature control modules
Install a DC power supply and a temperature control module inside the same control panel.
(11)Flexible high-speed I/O control module
Take following measures.
• Attach a ferrite core to the cable for the DC power connected to the flexible high-speed I/O control module,
• Install the DC power in the same control panel where the module is installed.
• Use a shielded cable when a DC power cable is laid out of the control panel.
• The length of the cable connected to an output part or external devices must be 2m or less for open collector
• The length of the cable connecting an input part and external devices must be 30m or less.
