Precautions
Refertothe DeviceNetOperation Manual(W267)before using the
Module.
Wiring
·To preventinductive noise,do notwire powerlinesor
high-tension linesalong with ornearthe cables.Other
noise-prevention techniques,such asusing shielding or
separateconduit/ducting,are also effective.
·Install the Module asfaraspossiblefromequipment that
generates strong high-frequency signals(such ashigh-fre-
quency welders)and equipment thatgenerates surges.Such
equipmentcan causethe Moduletomalfunction.
·Install surge absorbersornoisefilterson nearbyequipment that
generatesnoise,particularlyequipment thathasinductive
components such asmotors, transformers,solenoids,or
magnetic coils.
·When using a noisefilterinthe powersupply,check the voltage
and currentand install the noisefilteras close aspossibletothe
Module.
