Precautions

●

Mounting  

●

Terminals  

●

Other Precautions  

• When

 

mounting more than two Relays  

side by side, keep a 3 mm gap  

horizontally and vertically between  

Relays to ensure a good heat  

dissipation. It may cause a malfunction  

if heat is not dissipated smoothly from  

the Rela

y

.  

• The

 

terminals fit FASTON receptacle  

250 and are suitable for positive-lock  

mounting. Use only Faston terminals  

with the specified numbers.  

• This

 

Relay is suitable for power load  

switching of air-conditioning  

compressors and power supplies, etc.  

Do not use the G4A to switch micro  

loads less than 100 mA, such as in  

signal applications.  

Select leads for connecting Faston  

receptacles with wire diameters that  

are within the allowable range for the  

load current.  

Do not apply excessive force to the  

terminals when mounting or  

dismounting the Faston receptacle.  

Insert and remove terminals carefully  

one at a time. Do not insert terminals  

at an angle, or insert/remove multiple  

terminals at the same time.  

Refer to the following table for  

recommendations of connectors made  

by OMRON.
