1.04 WARRANTY
a. An 18-month parts warranty shall be provided
on materials and workmanship from the date
of invoice from an authorized distributor.
1.05 QUALITY ASSURANCE
a. The manufacturer of the AC Drive shall be a
certified ISO 9001 facility.
b. The AC Drive and all associated optional
equipment shall be UL LISTED according to
UL508C Power Conversion Equipment. A UL
label shall be attached inside each enclosure
as verification.
c. The AC Drive shall be designed constructed
and tested in accordance with NEMA, NEC,
VDE, IEC standards.
d. Every power converter shall be tested with an
actual ac induction motor, 100% load and
temperature cycled within an environmental
chamber at 104 °F. Documentation shall be
furnished to verify successful completion at
the request of the engineer.
e. All Drive door mounted pilot devices shall be
tested to verify successful operation.
Documentation shall be furnished upon
written request of the engineer.
f. The AC Drive shall undergo QA test
procedures and be submitted to a hi-pot test
with all enclosed devices mounted and wired,
prior to shipment.
PART 2 PRODUCT
2.01 MANUFACTURERS
a. The AC Drive shall be provided by Square D/
Groupe Schneider, Class 8839 58M
Enclosed, Class 8839 Type CPDM
“PowerGard™” or prior approved equal.
Substitutions must be submitted in writing
three (3) weeks prior to original bid date with
supporting documentation demonstrating that
the alternative manufacturer meets all aspects
of the specifications herein.
b. Alternate control techniques other than pulse
width modulated (PWM) are not acceptable.
2.02 GENERAL DESCRIPTION
Note to Specifier: For AC Drives rated up to
100 hp, the most practical harmonic mitigation
technique can be line reactors, isolation
transformers or harmonic suppressors dependent
upon the type of power quality concerns. For AC
Drives rated 125 hp and above, 18-Pulse offers a
premium level of harmonic mitigation.
a. The AC Drive shall convert the input AC mains
power to an adjustable frequency and voltage
as defined below.
1. For AC Drives rated up to 100 hp, the AC
Drive manufacturer shall use a 6-Pulse
bridge rectifier design [with line reactors,
isolation transformers for effective
harmonic mitigation]. The diode rectifiers
shall convert fixed voltage and frequency,
AC line power to fixed DC voltage. The
power section shall be insensitive to phase
rotation of the AC line.
2. For AC Drives rated 125 hp and above, the
AC Drive manufacturer shall supply an 18-
Pulse topology using a multiple bridge
rectifier design with integral reactor and
phase shifting transformer. The 18-Pulse
configuration shall result in a multiple
pulse current waveform that approximates
near sinusoidal input current waveform.
The power section shall be insensitive to
phase rotation of the AC line.
b. The output power section shall change fixed
DC voltage to adjustable frequency AC
voltage. This section shall use insulated gate
bipolar transistors (IGBT) or intelligent power
modules (IPM) as required by the current
rating of the motor.
2.03 CONSTRUCTION
a. AC Drives rated 25 hp VT at 460 Vac and less
shall be supplied in wall mounted enclosures
unless compartmentalized, floor mounted
enclosures are required for Barriered Bypass
construction. (See Emergency Full Speed
Requirements.) AC Drives rated 30 hp VT at
460 Vac and above shall be supplied in floor
mounted enclosures.
b. Seismic ratings and certifications shall be
provided for all floor mounted enclosures. The
seismic ratings shall meet IBC 2000, NFPA
5000, ASCE 7-02, UBC zone 4, CDC zone 4
and the 1995 NBCC with exceptions for
application in the British Columbia area and
the New Madrid Hazard Zone. Verification of
testing shall be in accordance with ICC AC156
Acceptance Criteria testing procedures.
Enclosures shall exhibit a certification label on
the inside enclosure door stating compliance
to these requirements.
c. The AC Drive shall be mounted in a [Type 1,
Type 12] enclosures with an external operated
disconnect device. For AC Drives greater than
75 hp (CT) or 100 hp (VT), NEMA Type 12 or
Type 1G ventilated enclosures with gaskets
and filters are acceptable.
