11 Spare and Optional Parts11.1 Spare PartsTable 17 lists the order numbers for the logic board and cooling fan(s) plus the quantity required for each soft starter.11.1.1 Soft Starter Amps, U c and U eThree ratings identify each soft starter: current in amps (In Line or Inside Delta), control supply voltage U c (24 V DC,115 V AC, 230 V AC) and main supply voltage U e (200 - 460 V AC, 400 - 600 V AC). Each spare part relates to one ormore of the ratings, e.g., each cooling fan corresponds to the Amps and U c ratings regardless of the U e ratings (U e= All, where All means either main voltage selection).English11.1.2 Fan OrientationBetween one and three cooling fans are used per soft starter depending on the ratings. When one fan is used, it ismounted centrally along the width of the unit. When two fans are used, one is mounted to the left (L) and the otherto the right (R). Left and right are defined by facing the cover of the unit, consequently, the fan on the left is thefurthest from the control terminals. Similarly, when three fans are used, mounting locations are left (L), center (Ctr),and right (R).Catalog No.Number ofFansU c = 24 V DCU e = AllTable 17 : Spare Parts, Logic Board and Cooling Fan Order NumbersNumber ofFansU c = 115 V ACU e = AllNumber ofFansU c = 230 V ACU e = AllLogic Board3RW34... 3RW39 50-6DC28 3RW39 50-6DC38 3RW39 50-6DC48Cooling Fan3RW34 55 -583RW34 65/66/673RW34 683RW34 83/843RW34 86212333RW39 50-8DC283RW39 60-8DC283RW39 60-8DC283RW39 72-8DC283RW39 73-8DC28212333RW39 50-8DC383RW39 60-8DC383RW39 60-8DC383RW39 60-8DC383RW39 60-8DC38212333RW39 50-8DC483RW39 60-8DC483RW39 60-8DC483RW39 60-8DC483RW39 60-8DC4811.2 Optional Parts11.2.1 Overload RelaysThe standard SIKOSTART Soft Starter does not include overload protection.
