Frame size D-E
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.
Terminal number Function
100, 101 Auxiliary supply S, T
102, 103 Internal supply S, T
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 5 amp fuse should be
used for protection. In UL applications, this should be a LittleFuse KLK-5 or equivalent.

Branch circuit protection
In order to protect the installation against electrical and fire hazard, all branch circuits in
an installation, switch gear, machines, etc., must be short-circuited and overcurrent
protected according to national/international regulations.
