If the adjustable frequency drive 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.

Table 3.23
The connector located on the power card provides the AC
line voltage connection for the cooling fans. The fans are
factory-equipped to be supplied from a common AC line
(jumpers between 100-102 and 101-103). If an external
supply is needed, the jumpers are removed and the supply
is connected to terminals 100 and 101. A 5A fuse should
be used for protection. In UL applications, this should be a
LittleFuse KLK-5 or equivalent.
