INSTALLATION
General Specifications
Frequency Range
1.7 to 180 Hz
You must make certain that the motor and
associated equipment are capable of
operating safely, and that protective guards
are in place, before you operate your drive
above 60 Hz.
Input Line Conditions
¥ Three phase 240 VAC, three phase 480
VAC, or single phase 240 VAC (±10 %).
¥ Input line impedance - 1% to 5%. You must
purchase a 1% input line reactor if you
calculate or measure input line
impedance less than 1%.
¥ Line Distortion - The harmonic voltage
distortion of the input power line should be
limited to 10% or less including distortion
caused by the drive(s). (See IEEE
Standard 519.)
¥ Input phase voltage unbalance less than 3%
(per IEEE Standard 446).
¥ Single phase input protection - drive will
safely run on single phase until input current
rating of the drive is exceeded. The output
current rating must be derated by 50%
for all drives except the 2 Hp, 240 VAC
unit (AF93AG0B002D) when single phase
240 V power is supplied. The 2 Hp, 240
VAC unit is fully rated for single phase or
three phase application.

! Caution
It is your responsibility to check your installation
to make sure it meets the conditions stated in
these specifications before you install your
Adjustable Frequency Drive. Operation of the
drive outside of these specifications will void
your warranty.
¥ Drive insensitive to line phase sequence.
¥ Suitable for use on a circuit capable of
delivering not more than 65K RMS
symmetrical amperes, 480 volts maximum.
Input Line Transients
¥ Drive protected and operational for line
transients to ANSI C62.41 (formerly IEEE 587)
and IEC 801.
¥ Drive protected (but may trip) for severe or
prolonged transients per IEEE 446.
Operator Interface
The AF93/IS903 operator interface consists of:
¥ An LCD display (two rows of 16 characters per
row) and keypad.
¥ Operator can display operating conditions,
parameter settings, or English language
diagnostic messages on the LCD.
¥ Operator can change the settings of a predefined
list of parameters.
¥ Operator can issue Start, Stop, Forward, and
Reverse commands and change speeds using
the keypad. Keypad can also be set for
remote Start and speed change.
