Terminal No.
Function
100, 101
Auxiliary supply S, T

Internal supply S, T
The connector located on the power card provides the connection of line voltage for the cooling fans. The fans are connected from factory to be supplied
form a common AC line (jumpers between 100-102 and 101-103). If external supply is needed, the jumpers are removed and the supply is connected
to terminals 100 and 101. A 5 Amp fuse should be used for protection. In UL applications this should be LittleFuse KLK-5 or equivalent.
