8.2.4 External Fan Supply
Frame size D-E-F
In case the frequency converter is supplied by DC or if the fan must run independently of the power supply, an external power supply can be applied.
The connection is made on the power card.
Terminal No.
100, 101
102, 103
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.
