3. Notes on PC Board Mounting
•Whenmounting2ormorerelaysonaPCboard,keepa
minimumspacingof5mmineachdirection.
•Manualsoldering:Soldertheterminalsat350°Cwithin
3sec.Usingasolderingironof60W(Sn-Ag-Cutype)is
recommended.
•Auto-soldering:Solderat
250°Cwithin4to5sec.
•Becausetheterminalislledwithepoxyresin,donot
excessivelysolderorbendtheterminal.Otherwise,air
tightnesswilldegrade.
•Avoidtouchingtherelaycoverortheepoxylledterminal
withthesolderingiron.
•Useanon-corrosiveresinux.
4. Others
1. Generalnotice:
•Tomaintaintheinitialcharacteristics,donotdropor
shocktherelay.
•Therelaycovercannotberemovedfromthebaseduring
normaloperation.Tomaintaintheinitialcharacteristics,
donotremovetherelaycover.
•Usetherelayinenvironmentsfreefromdust,sulfur
dioxide(SO2),hydrogensulde(H2S),ororganicgases.
•Makesurethatthecoilvoltagedoesnotexceedthe
applicablecoilvoltagerange.

causesincorrectoperationoftheload.Takethefollowing
measuresintoconsideration.
