Application Precautions
5
• Observe the following precautions when wiring the communications
cable.
• Separate the communications cables from the power lines or high-ten-
sion lines.
• Do not bend the communications cables.
• Do not pull on the communications cables.
• Do not place heavy objects on top of the communications cables.
• Be sure to wire communications cable inside ducts.
• Use appropriate communications cables.
• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied in places where the power supply
is unstable. An incorrect power supply may result in malfunction.
• Install external breakers and take other safety measures against short-cir-
cuits in external wiring. Insufficient safety measures against short-circuits
may result in burning.
• Double-check all the wiring and switch settings before turning ON the
power supply.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected opera-
tion.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• After replacing Units, resume operation only after transferring to the new
CPU Unit and/or Special I/O Units the contents of the DM Area, HR Area,
and other data required for resuming operation. Not doing so may result
in an unexpected operation.
• When transporting or storing the product, cover the PCBs with electrically
conductive materials to prevent LSIs and ICs from being damaged by
static electricity, and also keep the product within the specified storage
temperature range.
• When transporting the Unit, use special packing boxes and protect it from
being exposed to excessive vibration or impacts during transportation.
• Do not attempt to disassemble, repair, or modify any Units.
• Do not attempt to remove the cover over the non-used connector hole on
the front of the CS1W-PRM21 Unit.
