CAUTION STATEMENTS
710-13019-00A MVS User Manual Page 3
This symbol is used throughout this manual to draw attention to topics of special importance to the
installation and operation of MVS Series soft starters.
Caution Statements cannot cover every potential cause of equipment damage but can highlight common causes of
damage. It is the installer's responsibility to read and understand all instructions in this manual prior to installing, operating
or maintaining the soft starter, to follow good electrical practice including applying appropriate personal protective
equipment and to seek advice before operating this equipment in a manner other than as described in this manual.
Read and understand the entire manual before installing operating, or maintaining the starter. Follow all
applicable local and national codes.
Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
Use only electrically insulated tools and clothing and insulated protective gear when working around electrical
equipment.
Disconnect all power and ensure that the starter is de-energised before servicing the starter.
Do not rely on visual indications such as switch position or fuse removal for determining a de-energised
condition. Always assume that a terminal is energised until it is checked with a properly rated meter to ensure
that a terminal is de-energised and grounded.
Isolate the soft starter completely from the power supply before attempting any work on the starter or motor.
Always use a properly rated voltage sensing device to confirm power is off.
Before servicing the starter, ensure that all static charge has been discharged by grounding it with an appropriate
grounding device.
Metal swarf in the cabinet can cause equipment failure.
Do not apply voltage to the control input terminals. These are active 24 VDC inputs and must be controlled
with potential free contacts.
Contacts or switches operating the control inputs must be suitable for low voltage, low current switching (ie gold
flash or similar).
Cables to the control inputs must be segregated from mains voltage and motor cabling.
Some electronic contactor coils are not suitable for direct switching with PCB mount relays. Consult the
contactor manufacturer/supplier to confirm suitability.
The examples and diagrams in this manual are included solely for illustrative purposes. The information contained in this
manual is subject to change at any time and without prior notice. In no event will responsibility or liability be accepted for
direct, indirect or consequential damages resulting from the use or application of this equipment.
WARNING - ELECTRICAL SHOCK HAZARD
MVS soft starters contain dangerous voltages when connected to mains voltage. Only a qualified electrician
should carry out the electrical installation. Improper installation of the motor or the soft starter may cause
equipment failure, serious injury or death. Follow this manual and local electrical safety codes.
SHORT CIRCUIT
MVS soft starters are not short circuit proof. After severe overload or short circuit, the operation of the soft
starter should be fully tested by an authorised service agent.
GROUNDING AND BRANCH CIRCUIT PROTECTION
It is the responsibility of the user or person installing the soft starter to provide proper grounding and branch
circuit protection according to local electrical safety codes.
ARC FLASH HAZARD
Soft starters have a potential risk of arc flash. When insulation or isolation between electrified conductors is
breached or can no longer withstand the applied voltage, a short circuit occurs through the air. This may cause
a phase-to-ground and/or a phase-to-phase fault.
AuCom soft starters have been designed to mitigate an arc fault, however it is the responsibility of the site
engineer to ensure that personnel are protected from serious injury that may result from an arc fault.
Although unlikely, arc fault can be caused by:
Contamination in the insulation caused by deterioration over time
Section 1 Caution Statements

CAUTION STATEMENTS
Page 4 MVS User Manual 710-13019-00A
Inadequate insulation system on cable terminals
Overvoltage
Incorrect protection coordination settings
Overheating of the contact area, due to incorrect tightening of connections
Introduction of foreign matter, including swarf, vermin, tools or maintenance equipment left in the starter
STORAGE
The starter must be stored in its original packaging in a clean and dry environment. The starter should be
unpacked only after the equipment room is ready for installation. Particular care should be taken to avoid
exposure of the electronics to cement and/or concrete dust.

GENERAL DESCRIPTION
710-13019-00A MVS User Manual Page 5
2.1 Overview
The MVS provides compact and robust soft start solutions for control of medium voltage motors. MVS soft starters
provide a complete range of motor and system protection features and have been designed for reliable performance in the
most demanding installation situations.
Each MVS soft starter comprises two elements:
a power assembly
a controller module
The power assembly and controller module are supplied as a pair and share the same serial number. Care should be
taken during installation to ensure the correct controller and power assembly are used together.
Each MVS is also supplied with two fibre-optic cables, to connect the controller module to the power assembly, and three
non-conduction lead assemblies, allowing the soft starter to be tested with a low-voltage motor (< 500 VAC).

2.3 Key Features
MVS soft starters offer several special functions to ensure ease of use and to provide optimal motor control in all
environments and applications.
Customisable Protection
The MVS offers comprehensive protection to ensure safe operation of the motor and soft starter. The protection
characteristics can be customised extensively to match the exact requirements of the installation.
Use parameter group 4 on page 28 to set the conditions in which each protection mechanism will activate.
Example: use parameter 4C
Undercurrent to set the level for an undercurrent trip and parameter 4D
Undercurrent Delay to set a delay on the trip.
Use parameter group 16 on page 39 to select the soft starter's response when a protection mechanism activates. Each
protection can be set to trip the starter, activate a warning flag, or be ignored. All protection activations are recorded in
the event log, regardless of the protection class setting.
Example: Use parameter 16C
Undercurrent to select the response for an undercurrent trip (trip, warn or write
to log). The default response is trip.
NOTE
MVS soft starters have built-in trip points to ensure operation remains within the soft starter's capability.
These internal trips cannot be overridden. Certain faults within the MVS will also prevent the soft starter
from operating. Refer to
Troubleshooting on page 54 for details.
Advanced Thermal Modelling
Intelligent thermal modelling allows the soft starter to predict whether the motor can successfully complete a start. The
MVS uses information from previous starts to calculate the motor's available thermal capacity, and will only permit a start
which is predicted to succeed.
This feature can be enabled or disabled using parameter 4N Motor Temperature Check .
Comprehensive Event and Trip Logging
The MVS has a 99-place event log to record information on soft starter operation. A separate trip log stores detailed
information about the last eight trips.
Informative Feedback Screens
A digital display screen allows the MVS to display important information clearly. Comprehensive metering information,
details of starter status and last start performance allow easy monitoring of the starter's performance at all times.
Dual Parameter Set
The MVS can be programmed with two separate sets of operating parameters. This allows the soft starter to control the
motor in two different starting and stopping configurations.
The secondary motor settings (parameter groups 9 and 10) are ideal for dual speed motors or conventional (squirrel-cage)
motors which may start in two different conditions (such as loaded and unloaded conveyors).
NOTE
MVS soft starters are not suitable for controlling two separate motors. The secondary parameter set
should only be used for a secondary configuration of the primary motor.
The MVS will use the secondary motor settings to control a start when instructed via a programmable input (refer to
parameters 6A and 6F
Input A or B Function ).
Fibre Optics
The MVS uses two-line fibre optic connections between the low voltage control module and the high voltage power
assembly for electrical isolation. This fibre optic link simplifies installation of chassis mount MVS starters into custom panels.

4.2 Mounting Instructions - Controller
The Controller is secured into place using ten M4 nuts, affixed to the studs on the back of the controller.
To mount the controller, make a 186 mm x 300 mm cutout at the desired mounting location. Ensure adequate clearance
(>85 mm) is available behind the mounting location.If you intend to use a communication module, allow for a minimum
clearance of 120 mm behind the mounting panel.
Drill 5 mm holes to accommodate the studs on the controller. Fit the controller through the cutout and tighten the nuts
onto the studs.
NOTE
Before installation, always ensure that you are using the correct controller for the soft starter. This can
be checked by comparing the serial number on the back of the controller with the serial number on the
front of the power assembly.

4.4 Earth Terminations
A 10 mm earth stud is located on each side of the power assembly, at the rear of the unit. Use only M10 high tensile grade
8.8 threaded fasteners for all terminations. Use a pre-load torque setting between 28 ~ 30 Nm. Use only Belleville
washers.
4.5 Control Terminations
On the control voltage terminal block, control wiring is secured in place by 3 mm spring terminals. Use a screwdriver to
open the terminal clamp, then insert the wire into the terminal cage. Release the clamp by removing the screwdriver.

4.6 Control Wiring
The soft starter can be controlled in three ways:
using the buttons on the Controller
via remote inputs
via a serial communication link
The LCL/RMT button controls whether the MVS will respond to local control (via the Controller) or remote control (via
the remote inputs).
The Local LED on the Controller is on when the soft starter is in local control mode and off when the soft starter is in
remote control mode.
Control via the serial communication network is always enabled in local control mode, and can be enabled or disabled in
remote control mode (refer to parameter 6R). Control via the serial communication network requires an optional
communication module.
The STOP button on the Controller is always enabled.
The MVS has three fixed inputs for remote control. These inputs should be controlled by contacts rated for low voltage,
low current operation (gold flash or similar).

CAUTION
Do not apply voltage to the control input terminals. These are active 24 VDC inputs and must be
controlled with potential free contacts.
Cables to the control inputs must be segregated from mains voltage and motor cabling.
The reset input can be normally open or normally closed. Use parameter 6M to select the configuration.
NOTE
Reset input is normally closed by default.
4.7 Terminal Block (Controller)
Terminations on the Controller use plug-in terminals. Unplug the terminal blocks, complete the wiring, then re-plug the
terminal blocks into the controller.
4.8 Power Circuits
Overview
MVS soft starters are designed to operate as part of a system including other components. A main contactor and bypass
contactor are required in all installations. MVS models V02 ~ V07 must be installed with fuses.
The following additional components may also be required:
main isolator/ earth switch
power factor correction
line inductors
transient/ overvoltage protection
MV/LV control supply transformer
Main Contactor
The MVS must always be installed with a main contactor. Select a contactor with an AC3 rating greater than or equal to
the full load current rating of the connected motor or there is an option for a circuit breaker above 7.2 kV.
The main contactor is associated with terminals L1, L2, L3 on the supply side of the soft starter. The coil is associated with
output terminals 13, 14 of the MVS (refer to
Power Circuit Configuration ).
To ensure that the potentially dangerous medium voltage area is isolated from the low voltage control area, power is
supplied to the main contactor coil from the control voltage terminal block (refer to
Internal Wiring ).
Bypass Contactor
The MVS must always be installed with a bypass contactor. Select a contactor with an AC1 rating greater than or equal
to the full load current rating of the connected motor or there is an option for a circuit breaker above 7.2 kV.
