User Manual 

At maximum ambient temperature, the total sensor power from all inputs must not 
exceed:  
IMx-

S 16 10 W

 

IMx-

S 32 10 W (at 60

 

˚

C [

140 °F

] only ICP sensors are recommended) 

At lower temperatures more total sensor power is allowed; please contact SKF 
Condition Monitoring Center Luleå or application engineer. 

 

Important - Do NOT change DIP switch settings while the IMx-S unit is powered-
up, as this may cause damage and void warranty. 

 

Important - Before powering up the IMx-S unit, make sure that DIP switch settings 
are properly set to match the recommendations for the connected sensors. 
Incorrect settings may cause permanent damage to the IMx-S unit.
