Fuses 

 

The ICS-6-OEM has a number of internal protection fuses which might blow under conditions of fault 
or wiring error. In particular the safety loop fuses are usually blown if during wiring the A and B 
safety loops are crossed over. 
 
The following fuses are located inside the top of the unit. To access them, the front panel of the ICS-
6-OEM must be removed. Insert the blade of a 3mm flat screwdriver into the rectangular slot at the 
ends of the front panel and carefully prise it off.
