Frame 9 Blower Operation
Frame 9 drives use a single-phase capacitor bank fan and a three-phase blower for cooling. Proper phasing must be
supplied to terminals R, S, and T of the Power Terminal Block (AC drives) or the Blower Terminal Block (DC drives) to
assure correct blower rotation. To verify this, a Phase Monitor is used.

IP00, NEMA/UL Type Open 500 VA 1 TB9
A transformer matches the input line voltage to the
internal fan voltage. If line voltage is different than
the voltage class specified on the drive nameplate,
it may be necessary to change transformer taps
(see diagram).

Input
IP00, NEMA/UL Type Open 500 VA 2 TB9
A transformer matches the input line voltage to the
internal voltage used for the capacitor fan and
phase detector module. If the line voltage is
different than the voltage class specified on the
drive nameplate, it may be necessary to change
transformer taps (as shown).
