• Remove the stickers after the completion of wiring to ensure proper heat dis-
sipation. Operating the Unit with the sticker in place may cause heat build-up
and possible faulty operation.
• Use crimp terminals for wiring. Wiring bare wires directly to terminals may
result in a fire.
• Be sure that terminal blocks and connectors are correct before connecting
them. Improper connection may damage the Units.
The following precautions are necessary to ensure the general safety of the sys-
tem. Always heed these precautions.
• Provide double safety mechanisms to handle incorrect signals that can be
generated by broken signal lines or momentary power interruptions.
• Provide external interlock circuits, limit circuits, and other safety circuits in
addition to any provided within the PC to ensure safety.
When using the PC Card, be sure to observe the following precautions.
• Insert or eject the PC Card for at least 10 seconds after it is inserted or ejected.
(That is, don't eject the PC Card for at least 10 seconds after it is inserted and
don't insert the the PC Card for at least 10 seconds after it is ejected.)
• Don't eject the PC Card while it is being accessed (while either the CARD1
indicator or CARD2 indicator is lit).
PC Card Units that meet EC directives must be installed as follows:
1. PC Card Units are defined for installation inside control panels, so they must
all be installed within control panels. In addition, the control panels must be
grounded, enclosed metal housings.
2. Used reinforced insulation or double insulation for the DC power supplies
used for the communications power supply, internal circuit power supply,
and the I/O power supplies.
3. PC Card Units that meet EC directives also meet the common emission
standard (EN50081-2). When PC Card Units are built into equipment, how-
ever, the measure necessary to ensure that the standard is met will vary with
the overall configuration of the control panel, the other devices connected to
the control panel, and other conditions. You must therefore confirm that EC
directives are met for the overall machine or device.
To reduce noise, wire the control panel with as thick and short electric lines as
possible and ground to 100 Ω min.
