Introduction
Caution Statements
1
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
adhere to all instructions in this manual, to follow good electrical practice and to
seek advice before operating this equipment in a manner other than as described
in this manual.
• Ensure that the soft starter is completely isolated from the power supply before
attempting any work on the unit.
• Entry of metal swarf into 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 circuits.
• Ensure contacts or switches operating the control inputs are suitable for low
voltage, low current switching (ie gold flash or similar).
• Ensure cables to the control inputs are segregated from AC power and control
wiring.
• Some electronic contactor coils are not suitable for direct switching with PCB
mount relays. Consult the contactor manufacturer/ supplier to see if this is
advisable.
• Do not connect power factor correction capacitors to the output of MVS soft
starters. If static power factor correction is employed, it must be connected to
the supply side of the soft starter.
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 line
voltage. Only a competent 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, the National
Electrical Code (NEC®) and local 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.
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 the
National Electrical Code (NEC®) and local safety codes.

2.1 Overview
The MVS Series 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 resistor assemblies,
allowing the soft starter to be tested with a low-voltage motor (< 500 VAC).

Installation
Key Features
The MVS offers several special functions to ensure safe and simple installation and
configuration.
Comprehensive Simulations
The MVS offers software-based simulation functions to check all aspects of
operation, including starting and stopping, protection mechanisms and signal inputs
and outputs. The simulations are accessed via the Commissioning Menu.
Low Voltage Test Mode
The low voltage test mode lets commissioning staff check the soft starter's
electrical configuration safely, without requiring access to specialised medium
voltage equipment. The MVS can start and stop a small three-phase motor, testing
associated equipment such as contactors and relays.

5.1 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. The following additional components may also be required:
• main isolator/ earth switch
• R Rated protection fuses
• power factor correction
• line inductors
• transient/ overvoltage protection
• control supply transformer
5.2 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.
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
Diagram 1: Standard Power Circuit Configuration on page 16).
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 Diagram 4: Internal Wiring on page 21).
5.3 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.
The bypass contactor is associated with terminals L1, L2, L3 on the supply side of
the soft starter, and bypass terminals T1B, T2B, T3B on the motor side. The coil is
associated with output terminals 23, 24, and the auxiliary Normally Open contact is
associated with input terminals C73, C74 of the soft starter (refer to Diagram 1:
Standard Power Circuit Configuration on page 16).
To ensure that the potentially dangerous medium voltage area is isolated from the
low voltage control area, power is supplied to the bypass contactor coil from the
control voltage terminal block (refer to Diagram 4: Internal Wiring on page 21).

5.4 Main Isolator/ Earth Switch
A main isolator/ earth switch can be connected on the supply side of the main
contactor (refer to Diagram 2: Complete Power Circuit Configuration on page 18).
CAUTION
The main isolator/ earth switch should only be operated when the motor
is not running.
5.5 R Rated Protection Fuses
If specified, R Rated protection fuses can be installed on the supply side of the soft
starter to provide Type 2 coordination and short circuit protection for the motor
branch circuit. The appropriate fuse should be selected from the table below,
based on the motor's rated full load current.
This recommendation is based on two starts per hour (equally spaced) and
maximum ambient operating temperature of 40 ºC. Consult your local supplier for
operating conditions not covered by these charts.

18R fuse for 6.6 kV: A072B1DARO-18R or JCR-B-18R
5.6 Power Factor Correction
Power factor correction capacitors should be selected based on the motor data and
the required final power factor.
If power factor correction capacitors are being used, select a contactor according to
the required kVAr. The contactor must be connected on the supply side of the soft
starter. The power factor correction capacitor contactor coil is associated with
output terminals 33, 34 of the soft starter's power interface PCB.
To ensure that the potentially dangerous medium voltage area is isolated from the
low voltage control area, power is supplied to the power factor correction capacitor
contactor coil from the control voltage terminal block (refer to Diagram 4: Internal
Wiring on page 21).
NOTE
The capacitor bank must be fed from the supply side of the soft starter.
5.7 Line Inductors
Line inductors are required if the cable run between the soft starter and the motor
is greater than 200 m. Line inductors should be installed outside the panel,
between the soft starter output (terminals T1, T2, T3) and the motor. Contact your
local supplier for selection details.
5.8 Transient/ Overvoltage Protection
Overvoltage protection should be installed if there is a risk of high transients at the
installation. If required, use the optional Overvoltage Protection Kit. Contact your
local supplier for details.

5.9 Control Supply Transformer
The MVS requires a low voltage control supply (110~130 VAC or 220~240 VAC).
If low voltage is not available, a transformer is required. Use a transformer with
primary voltage matching the mains voltage, and secondary voltage of 110 VAC.
Use a single phase 500 VA transformer with protection fuses on both the primary
and secondary sides (refer to Diagram 2: Complete Power Circuit Configuration on
page 18).
