Omron 3G8F5-DRM21-E - V2 Operation Manual page 18

Application Precautions
• 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-
cuiting in external wiring. Insufficient safety measures against short-cir-
cuiting 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.
• 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.
• Do not touch the mounted parts or the rear surface of PCBs because
PCBs have sharp edges such as electrical leads.
• Do not attempt to disassemble, repair, or modify any Units.
