Important Safety Information
Please read the IMPORTANT SAFETY INFORMATION below, and all Warning and Caution information elsewhere.
WARNING
Danger: Indicates a risk of electric shock, which, if not avoided, could result in damage to the
equipment and possible injury or death.
This variable speed drive product (PACMotion VFD) is intended for professional incorporation into complete
equipment or systems as part of a xed installation. If installed incorrectly it may present a safety hazard. The
PACMotion VFD uses high voltages and currents, carries a high level of stored electrical energy, and is used
to control mechanical plant that may cause injury. Close attention is required to system design and electrical
installation to avoid hazards in either normal operation or in the event of equipment malfunction. Only
qualied electricians are allowed to install and maintain this product.
System design, installation, commissioning and maintenance must be carried out only by personnel who
have the necessary training and experience. They must carefully read this safety information and the
instructions in this Guide and follow all information regarding transport, storage, installation and use of the
PACMotion VFD, including the specied environmental limitations.
Do not perform any ash test or voltage withstand test on the PACMotion VFD. Any electrical measurements
required should be carried out with the PACMotion VFD disconnected.
WARNING
Electric shock hazard! Disconnect and ISOLATE the PACMotion VFD before attempting any work on it. High
voltages are present at the terminals and within the drive for up to 10 minutes after disconnection of the
electrical supply. Always ensure by using a suitable multimeter that no voltage is present on any drive power
terminals prior to commencing any work.
Where supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have
elapsed after turning off the supply.
Ensure correct earthing connections and cable selection as dened by local legislation or codes. The drive
may have a leakage current of greater than 3.5 mA; furthermore the earth cable must be sufcient to carry
the maximum supply fault current which normally will be limited by the fuses or MCB. Suitably rated fuses or
MCB should be tted in the mains supply to the drive, according to any local legislation or codes.
Do not carry out any work on the drive control cables whilst power is applied to the drive or to the external
control circuits.
The “Safe Torque Off” Function does not prevent high voltages from being present at the drives power terminals.
GFK-3111A PACMotion VFD AC Variable Speed Drive User Guide 5
WARNING
Danger: Indicates a potentially hazardous situation other than electrical, which if not avoided, could
result in damage to property.
Within the European Union, all machinery in which this product is used must comply with the Machinery
Directive 2006/42/EC, Safety of Machinery. In particular, the machine manufacturer is responsible for
ensuring that the electrical equipment complies with EN60204-1 and providing a disconnecting device which

Installation Following a Period of Storage
Where the drive has been stored for some time prior to installation, or has remained without the main power
supply present for an extended period of time, it is necessary to reform the DC capacitors within the drive
according to the following table before operation. For drives which have not been connected to the main
power supply for a period of more than 2 years, this requires a reduced mains voltage mains voltage to be
applied for a time period, and gradually increased prior to operating the drive. The voltage levels relative to
the drive rated voltage, and the time periods for which they must be applied are shown in the following table.
Following completion of the procedure, the drive may be operated as normal.

Guidelines for Enclosure Mounting (IP20 Units)
• IP20 drives are suitable for use in pollution degree 1 environments, according to IEC-664-1. For pollution
degree 2 or higher environments, drives should be mounted in a suitable control cabinet with sufcient
ingress protection to maintain a pollution degree 1 environment around the drive.
• Enclosures should be made from a thermally conductive material.
• Ensure the minimum air gap clearances around the drive as shown below are observed when mounting
the drive.
• Where ventilated enclosures are used, there should be venting above the drive and below the drive to
ensure good air circulation. Air should be drawn in below the drive and expelled above the drive.
•
In any environments where the conditions require it, the enclosure must be designed to protect the
PACMotion VFD against ingress of airborne dust, corrosive gases or liquids, conductive contaminants (such
as condensation, carbon dust, and metallic particles) and sprays or splashing water from all directions.
• High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure.
The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to
allow air to circulate through the drive heatsink. Emerson recommend the following minimum sizes for drives
mounted in non-ventilated metallic enclosures:

Protective Earth (PE) Connection
Grounding Guidelines
Adequate safety earthing must be provided in accordance with local wiring rules and codes of practice.
The ground terminal of each PACMotion VFD should be connected back to the common safety earth bar
to maintain touch potentials within safe limits. The ground terminal of each PACMotion VFD should be
individually connected DIRECTLY to the site ground bus bar (through the EMC lter if installed). PACMotion
VFD ground connections should not loop from one drive to another, or to, or from any other equipment.
Ground impedance must conform to local industrial safety regulations and/or electrical codes.
To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections.
The integrity of all ground connections should be checked periodically.
Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply
conductors.
Motor Ground
The driven motor must be locally connected to a suitable ground location to maintain touch potentials within
safe limits. In addition, the motor ground must be connected to one of the ground terminals on the drive.
Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist. The PACMotion VFD is designed to produce the
minimum possible leakage current whilst complying with worldwide standards. The level of current is
affected by motor cable length and type, the effective switching frequency, the earth connections used and
the type of RFI lter installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the following conditions
apply:
• A Type B Device must be used.
• Individual device should be used for each PACMotion VFD.
• The device must be suitable for protecting equipment with a DC component in the leakage current.
• The device should be not sensitive to high frequency leakage current.
Shield Termination (Cable Screen)
The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield
connected to this terminal (drive end) should also be connected to the motor frame (motor end). Use a shield
terminating or EMI clamp to connect the shield to the safety ground terminal, refer to page 34.
GFK-3111A PACMotion VFD AC Variable Speed Drive User Guide 25
Incoming Power Connection
NOTE For IP20 Frame Size 8 it is important that the input supply phase orientation is correct, i.e. L1>L1,
L2>L2, L3>L3, failure to do so will result in a “Ph-Seq” trip.
WARNING
Ensure there is at least 30 seconds between each power-on.
Suitability
All PACMotion VFD models are designed for use on a single phase or balanced three phase supply depending
on the model.
For all models and ratings when working with an IT Supply network, or any power supply type where the
phase to earth voltage may exceed the phase to phase voltage (such as ungrounded supplies), the internal
EMC lter and surge protection must be disconnected before connecting the supply. Refer to section Internal
EMC Filter and Varistors – Disconnection Procedure on page 89 for further information.
For three phase supply models, a maximum of 3% imbalance is allowed between phases.
Cable Selection
• For 1 phase ac supply, power should be connected to L1/L, L2/N.
• For a DC Supply, the main power cables should be connected to L1/L, L2/N.
• For 3 phase ac supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is
not important. Neutral connection is not required.
For compliance with CE and C Tick EMC requirements, refer to section refer to page 34.
• A xed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed
between the PACMotion VFD and the main Power Source. The disconnecting device must conform to the
local safety code / regulations (e.g. within Europe, EN60204-1, Safety of machinery).
• The cables should be dimensioned according to any local codes or regulations. Maximum dimensions for
each drive model are given in section Input/Output Power and Current Ratings on page 84.
Fuse / Circuit Breaker Selection
• Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming
supply line, according to the data in section Input/Output Power and Current Ratings on page 84.
• The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or
UL type J fuses are suitable (exception: Eaton Bussmann FWP series must be used for size 6A & 6B IP20
models); however in some cases type aR fuses may be required. The operating time of the fuses must be
below 0.5 seconds.
• Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating
may be utilised in place of fuses, providing that the clearing capacity is sufcient for the installation.
• The maximum permissible short circuit current at the PACMotion VFD Power terminals as dened in
IEC60439-1 is 100 kA.
• The PACMotion VFD provides thermal and short circuit protection for the connected motor and motor
cable.
26 PACMotion VFD AC Variable Speed Drive User Guide GFK-3111A
Input Choke
An optional Input Choke is recommended to be installed in the supply line for drives where any of the
following conditions occur:
• The incoming supply impedance is low or the fault level / short circuit current is high.
NOTE For IP20 Frame Size 8 the input current level will vary according to supply impedance. At minimum a
1% line choke must be installed. Installing a 4% line choke further helps towards minimising harmonic current
distortion and total current levels. 1% and 4% line chokes are available.
• The supply is prone to dips or brown outs.
• An unbalanced supply system is used (3 phase drives) where the voltage levels during on load operation
exceed the designed 3% capacity of the PACMotion VFD.
• The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes).
In all other installations, an input choke is recommended to ensure protection of the drive against power
supply faults.
Operation of 3 Phase drives from a Single Phase Supply
A special function of PACMotion VFD allows all drives designed for operation on 3 phase supplies to be
operated on a single phase supply of the correct rated voltage at up to 50% of the nominal capacity.
For Example, Model Number ODP-2-64450-3KA4N can be operated on a single phase supply, 380 – 480 volts,
with the maximum output current limited to 45 Amps.
The supply must be connected to the L1 and L2 terminals of the drive.
Operation with DC Power Supply or Common DC Bus
PACMotion VFD models provide terminals to directly connect to the DC Bus for applications which require
this. For further information on using the DC Bus connections, please refer to your Emerson sales Partner.
Motor Connection
• The drive inherently produces fast switching of the output voltage (PWM) to the motor compared with
operation of the motor directly from the mains supply. Most modern industrial motors are wound for
operation with a variable speed drive and will have insulation rated accordingly. However, on some
motors the quality of insulation may be insufcient or unknown. In such cases the motor manufacturer
should be consulted and preventative measures may be required prior to operating with the drive.
• The motor should be connected to the PACMotion VFD U, V, and W terminals using a suitable 3 or 4 core
cable. Where a 3 core cable is utilised, with the shield operating as an earth conductor, the shield must
have a cross sectional area at least equal to the phase conductors when they are made from the same
material. Where a 4 core cable is utilised, the earth conductor must be of at least equal cross sectional
area and manufactured from the same material as the phase conductors.
• Automatic switchgear should not be installed between the drive output and the motor, opening and
closing contacts in this circuit whilst the drive is energised will inevitably reduce the lifetime of the drive
and could cause product failure. If an isolator is required to be placed between the drive and the motor in
order to comply with local regulations, the device must not be operated when the drive is running.
• For compliance with the European EMC directive, a suitable screened (shielded) cable should be used.
Braided or twisted type screened cable where the screen covers at least 85% of the cable surface area,
designed with low impedance to HF signals are recommended as a minimum. Installation within a
suitable steel or copper tube is generally also acceptable.
The motor earth must be connected to one of the PACMotion VFD earth terminals to provide a low
impedance path for common mode leakage current to return to the drive. This is best achieved in practice by
using a cable with suitable shielding which provides a low impedance path at high frequencies, and ensuring
correct, low impedance earth bonding of the motor cable at both ends. For further information, refer to
page 34.

Motor Terminal Box Connections
Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the
nameplate of the motor. This operational voltage is normally selected when installing the motor by selecting
either STAR or DELTA connection. STAR always gives the higher of the two voltage ratings.

Connecting a Brake Resistor
PACMotion VFD units feature an internal brake transistor, tted as standard for all models. The brake resistor
should be connected to the DC+ and BR terminals of the drive. These terminals are shrouded, and the
shrouding should be removed to access the terminals.

Software protection against brake resistor overload is carried out within the drive. For correct protection of
the brake resistor, the following settings are required:
• Set P1-14 = 201 (where 201 is the default password setting for advanced parameter access).
• Enter the resistance of the brake resistor in P6-19 (Ohms).
• Enter the power of the brake resistor in P6-20 (kW).

It is highly recommended to equip the drive with a main contactor
in order to provide an additional thermal overload protection for the
braking resistor.
The contactor should be wired so that it will open when the resistor
overheats, otherwise the drive will not be able to interrupt the main
supply if the brake chopper remains closed (short-circuited) in a fault
situation.
It is also recommended to wire the thermal overload protection to a
digital input of the drive as an External Trip.
