Note for SR55-156 and SR55-180 Soft Starters Cooling Fan Replacement
For SR55-156 and SR55-180 soft starters, the fans and internal fan supply voltage could
be either 12VDC or 24VDC, depending upon when the soft starter was manufactured. The
replacement fan kit (SR55-FAN-6) includes a 12VDC fan and a resistor for use in the 24VDC
starters as described below.
For early-model SR55-156 and SR55-180 soft starters, one of the original fans must be removed
to observe the voltage rating label. SR55-156 and SR55-180 soft starters with original equipment
24VDC fans will require two SR55-FAN-6 fans kits, and both fans will need to be replaced.
