Step 1: Read the Precautions
and General Information
Qualified Personnel
ATT EN TI ON : Only qualified personnel familiar with adjustable frequency AC
drives and associated machinery must plan or implement the installation, startup and subsequent maintenance of the system. Failure to comply can result in
personal injury and/or equipment damage.
Personal Safety
ATT EN TI ON : To avoid an electric shock hazard, verify that the voltage on the
bus capacitors has discharged before performing any work on the drive.
Measure the DC bus voltage at the following points (refer to pages 28
for locations):
30
• +DC and -DC terminals of the Power Terminal Block
• +DC terminal of the Power Terminal Block and the chassis
• -DC terminal of the Power Terminal Block and the chassis
The voltage must be zero for all three measurements.
through
ATT EN TI ON : Risk of injury or equipment damage exists. DPI or SCANport host
products must not be directly connected together via 1202 cables.
Unpredictable behavior can result if two or more devices are connected in this
manner.
ATT EN TI ON : The drive start/stop/enable control circuitry includes solid state
components. If hazards due to accidental contact with moving machinery or
unintentional flow of liquid, gas or solids exist, an additional hardwired stop
circuit can be required to remove the AC line to the drive. An auxiliary braking
method can be required.
ATT EN TI ON : Loss of control in suspended load applications can cause personal
injury and/or equipment damage. Loads must always be controlled by the drive
or a mechanical brake. Parameters 600…611 are designed for lifting/torque
proving applications. It is the responsibility of the engineer and/or end user to
configure drive parameters, test any lifting functionality and meet safety
requirements in accordance with all applicable codes and standards.
Rockwell Automation Publication 20B-IN019E-EN-P - July 20135
PowerFlex 700 Adjustable Frequency AC Drive – Frames 0…6
Product Safety
ATT EN TI ON : An incorrectly applied or installed drive can result in component
damage or a reduction in product life. Wiring or application errors, such as,
undersizing the motor, incorrect or inadequate AC supply, or excessive ambient
temperatures can result in malfunction of the system.
ATT EN TI ON : This drive contains ESD (Electrostatic Discharge) sensitive parts
and assemblies. Static control precautions are required when installing, testing,
servicing or repairing this assembly. Component damage can result if ESD
control procedures are not followed. If you are not familiar with static control
procedures, reference Guarding Against Electrostatic Damage, publication
8000-4.5.2 or any other applicable ESD protection handbook.
ATT EN TI ON : The “adjust freq” portion of the bus regulator function is
extremely useful for preventing nuisance overvoltage faults resulting from
aggressive decelerations, overhauling loads, and eccentric loads. It forces the
output frequency to be greater than commanded frequency, while the bus
voltage is increasing toward a level that causes a fault. However, it can also
cause either of the following two conditions to occur.
• Fast positive changes in input voltage (more than a 10% increase within 6
minutes) can cause uncommanded positive speed changes. However an
“OverSpeed Limit” fault (F25) occurs if the speed reaches [Maximum Speed] +
[Overspeed Limit], (parameters 82 and 83). If this condition is unacceptable,
action must be taken to 1) limit supply voltages within the specification of the
drive and, 2) limit fast positive input voltage changes to less than 10%.
Without taking such actions, if this operation is unacceptable, the “adjust freq”
portion of the bus regulator function must be disabled (see parameters 161
and 162).
• Actual deceleration times can be longer than commanded deceleration times.
However, a “Decel Inhibit” fault (F24) is generated if the drive stops
decelerating altogether. If this condition is unacceptable, the “adjust freq”
portion of the bus regulator must be disabled (see parameters 161 and 162). In
addition, installing a properly sized dynamic brake resistor provides equal or
better performance in most cases.
Important: These faults are not instantaneous. Test results have shown that they
can take between 2…12 seconds to occur.

EMC Instructions
CE Conformity
Conformity with the Low Voltage (LV) Directive and Electromagnetic
Compatibility (EMC) Directive has been demonstrated by using harmonized
European Norm (EN) standards published in the Official Journal of the
(1)
European Communities. PowerFlex Drives
listed below when installed according to the information supplied in this
publication and the Wiring & Grounding Guidelines Manual.
CE Declarations of Conformity are available online at:
• EN50178 Electronic equipment for use in power installations.
EMC Directive (89/336/EEC)
• EN61800-3 Adjustable speed electrical power drive systems Part 3: EMC
product standard including specific test methods.
comply with the EN standards
General Notes
• Some drives are equipped with an adhesive label on the top of the drive. If
the adhesive label is removed from the top of the drive, the drive must be
installed in an enclosure with side openings less than 12.5 mm (0.5 in.) and
top openings less than 1.0 mm (0.04 in.) to maintain compliance with the
LV Directive.
• The motor cable must be kept as short as possible to avoid electromagnetic
emission as well as capacitive currents.
• Use of line filters in ungrounded systems is not recommended.
• PowerFlex drives can cause radio frequency interference if used in a
residential or domestic environment. The installer is required to take
measures to prevent interference, in addition to the essential requirements
for CE compliance listed below, if necessary.
• Conformity of the drive with CE EMC requirements does not guarantee
an entire machine or installation complies with CE EMC requirements.
Many factors can influence total machine/installation compliance.
• PowerFlex drives can generate conducted low frequency disturbances
(harmonic emissions) on the AC supply system.
• When operated on a public supply system, it is the responsibility of the
installer or user to ensure, by consultation with the distribution network
operator and Rockwell Automation, if necessary, that applicable
requirements have been met.
(1) 600V class drives below 77A (Frames 0…4) are declared to meet the essential requirements of the Low Voltage D irective. It is the
responsibility of the user to determine compliance to the EMC directive.

Special Considerations
PowerFlex 700 drives are suitable for use on a circuit capable of delivering up to a
maximum of 200,000 rms symmetrical amperes.
ATT EN TI ON : To guard against personal injury and/or equipment damage
caused by improper fusing or circuit breaker selection, use only the
recommended line fuses/circuit breakers specified on page 33
If a system ground fault monitor (RCD) is to be used, only Type B (adjustable)
devices must be used to avoid nuisance tripping.
Unbalanced, Ungrounded, Resistive or B Phase Grounded Distribution Systems
If phase to ground voltage exceeds 125% of normal line to line voltage or the
supply system is ungrounded, refer to the Wiring and Grounding Guidelines for
Pulse Width Modulated (PWM) AC Drives, publication DRIVES-IN001
ATT EN TI ON : To guard against drive damage, PowerFlex 700 drives contain
protective MOVs and common mode capacitors that are referenced to ground.
These devices must be disconnected if the drive is not

Input Power Conditioning
Certain events on the power system supplying a drive can cause component
damage or shortened product life. These conditions are divided into 2 basic
categories:
1. All drives
• The power system has power factor correction capacitors switched in
and out of the system, either by the user or by the power company.
• The power source has intermittent voltage spikes in excess of 6000

• The nearest supply transformer is larger than 100 kVA or the available
short circuit (fault) current is greater than 100,000A.
• The impedance in front of the drive is less than 0.5%.
If any or all of these conditions exist, it is recommended that the user install a
minimum amount of impedance between the drive and the source. This
impedance could come from the supply transformer itself, the cable between the
transformer and drive or an additional transformer or reactor. The impedance
can be calculated by using the information supplied in Wiring and Grounding

ATT EN TI ON : National Codes and standards (NEC, VDE, BSI etc.) and local codes
outline provisions for safely installing electrical equipment. Installation must
comply with specifications regarding wire types, conductor sizes, branch circuit
protection and disconnect devices. Failure to do so can result in personal injury
and/or equipment damage.
EMC Compliance
Refer to page 7 for details.
CabIe Trays and Conduit
If cable trays or large conduits are to be used, refer to the guidelines presented in
the Wiring and Grounding Guidelines for Pulse Width Modulated (PWM) AC
Drives, publication DRIVES-IN001.
ATT EN TI ON : To avoid a possible shock hazard caused by induced voltages,
unused wires in the conduit must be grounded at both ends. For the same
reason, if a drive sharing a conduit is being serviced or installed, all drives using
this conduit must be disabled. This helps minimize the possible shock hazard
from “cross coupled” motor leads.
Motor Cable Lengths
Typically, motor lead lengths less than 30 meters (100 feet) are acceptable.
However, if your application dictates longer lengths, refer to the Wiring and
Grounding Guidelines for Pulse Width Modulated (PWM) AC Drives,
publication DRIVES-IN001
20B-TD001

Cable Types Acceptable for 200…600 Volt Installations
A variety of cable types are acceptable for drive installations. For many
installations, unshielded cable is adequate, provided it can be separated from
sensitive circuits. As an approximate guide, allow a spacing of 0.3 meters (1 foot)
for every 10 meters (32.8 feet) of length. In all cases, long parallel runs must be
avoided. Do not use cable with an insulation thickness less than or equal to 15
mils (0.4mm/0.015 in.). Use Copper wire only. Wire gauge requirements and
recommendations are based on 75 °C. Do not reduce wire gauge when using
higher temperature wire.
Unshielded Cable
THHN, THWN or similar wire is acceptable for drive installation in dry
environments provided adequate free air space and/or conduit fill rates limits are
provided. Do not use THHN or similarly coated wire in wet areas. Any wire
chosen must have a minimum insulation thickness of 15 Mils and must not have
large variations in insulation concentricity.

Shielded/Armored Cable
Shielded cable contains all of the general benefits of multi-conductor cable with
the added benefit of a copper braided shield that can contain much of the noise
generated by a typical AC Drive. Strong consideration for shielded cable must be
given in installations with sensitive equipment such as weigh scales, capacitive
proximity switches and other devices that can be affected by electrical noise in the
distribution system. Applications with large numbers of drives in a similar
location, imposed EMC regulations or a high degree of communications/
networking are also good candidates for shielded cable.
Shielded cable can also help reduce shaft voltage and induced bearing currents for
some applications. In addition, the increased impedance of shielded cable can
help extend the distance that the motor is from the drive without the addition of
motor protective devices such as terminator networks. Refer to the Reflected
Wave topic in the Wiring and Grounding Guidelines for Pulse Width Modulated
(PWM) AC Drives, publication DRIVES-IN001
Consideration must be given to all of the general specifications dictated by the
environment of the installation, including temperature, flexibility, moisture
characteristics and chemical resistance. In addition, a braided shield must be
included and be specified by the cable manufacturer as having coverage of at least
75%. An additional foil shield can greatly improve noise containment.
.
A good example of recommended cable is Belden® 295xx (xx determines gauge).
This cable has four (4) XLPE insulated conductors with a 100% coverage foil and
an 85% coverage copper braided shield (with drain wire) surrounded by a PVC
jacket.
Other types of shielded cable are available, but the selection of these types can
limit the allowable cable length. Particularly, some of the newer cables bundle 4
conductors of THHN wire and wrap them tightly with a foil shield. This
construction can greatly increase the cable charging current required and reduce
the overall drive performance. Unless specified in the individual distance tables as
tested with the drive, these cables are not recommended and their performance
against the lead length limits supplied is not known. See Ta b l e 3

Single-Phase Input Power
The PowerFlex 700 drive is typically used with a three-phase input supply. Singlephase operation is possible with output current derated by 50% (at maximum
ambient temperature of 25 °C) of the three-phase ratings. Refer to tables 4
through 6
.
AC Input Phase Selection (Frames 5…6 Only)
ATT EN TI ON : To avoid a shock hazard, ensure that all power to the drive has
been removed before performing the following.
Moving the “Line Type” jumper on the Precharge Board (see below) allows single
or three-phase operation.
When selecting single-phase operation, input power must be applied to the
R (L1) and S (L2) terminals. This ensures that the fan is properly powered.
