CAUTION STATEMENTS
2. Caution Statements
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 equipment, 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 MVE. Follow all
applicable local and national codes.
•Apply appropriate personal protective equipment (PPE) and clothing, and follow safe electrical work
practices.
•Disconnect all power and ensure that the MVE is de-energised before servicing the equipment.
•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 and ensure that a terminal is
de-energised and grounded.
•Isolate the MVE completely from the power supply before attempting any work on the MVE or motor.
•Always use a properly rated voltage sensing device to confirm power is off.
•Before servicing the MVE, ensure that all static charge has been discharged by grounding it with an
appropriate grounding device.
•Metal debris in the enclosure can cause equipment failure.
•The control inputs are powered by the soft starter. Do not apply external voltage to the control input
terminals.
•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 contactor coils are not suitable for direct switching with PCB mount relays.
WARNING - ELECTRICAL SHOCK HAZARD
The MVE contains dangerous voltages when connected to mains voltage. Only a qualified electrician should
carry out the electrical installation. Improper installation of the motor or the MVE may cause equipment
failure, serious injury or death. Follow this manual and local electrical safety codes.
SHORT CIRCUIT
The MVE is not short circuit proof. After severe overload or short circuit, the operation of the MVE 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 MVE to provide proper grounding and branch
circuit protection according to local electrical safety codes.
ARC FLASH HAZARD
Medium voltage equipment has 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.
Although unlikely, arc fault can be caused by:
•Contamination in the insulation caused by deterioration over time
•Inadequate insulation system on cable terminals
•Overvoltage
•Incorrect protection coordination settings
•Overheating of the contact area, due to incorrect tightening of connections
•Foreign matter, such as metal debris, vermin, tools or maintenance equipment left in the starter
AuCom medium voltage equipment has 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.

INSTALLATION
5.3 Power Circuits
Overview
MVE soft starters are designed to operate as part of a system including other components.
•A bypass switching device (contactor or vacuum circuit breaker) is required in all installations.
•A main switching device (contactor or circuit breaker) is required in all installations. This can be located
in the soft starter panel or the upstream feeder panel.
•If contactors are used for one or both switching devices, appropriately rated fuses must be installed
upstream of the main switching device to provide short circuit protection if the short circuit level of the
network/supply is higher than the short circuit rating of the contactor.
Additional components may also be required to comply with soft starter panel specifications.
Main Switching Device
The MVE can be installed with a main contactor or a circuit breaker.
•Select a contactor with an AC3 rating greater than or equal to the full load current rating of the
connected motor.
•Select a circuit breaker greater than or equal to the full load current rating of the connected motor.
The main switching device 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 MVE.
To ensure that the potentially dangerous medium voltage area is isolated from the low voltage control area, power is
supplied to the main switching device coil from the control voltage terminal block.
Bypass Switching Device
The MVE must always be installed with a bypass contactor or circuit breaker.
•Select a contactor with an AC3 rating greater than or equal to the full load current rating of the
connected motor.
•Select a circuit breaker greater than or equal to the full load current rating of the connected motor.
The bypass switching device 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.
To ensure that the potentially dangerous medium voltage area is isolated from the low voltage control area, power is
supplied to the bypass switching device coil from the control voltage terminal block.
R Rated Protection Fuses
If contactors are used for one or both switching devices, appropriately rated fuses must be installed upstream of the
main switching device to provide short circuit protection if the short circuit level of the network/supply is higher than
the short circuit rating of the contactor. Select the appropriate fuse based on the motor's rated full load current.
Transient/ Overvoltage Protection
Overvoltage protection should be installed if there is a risk of high voltage transients at the installation. Contact your
local supplier for details.
Line Inductors
Output line inductors may be required depending on various factors, including the soft starter model, the system
operating voltage, the cable type, and the length of the cable run between the soft starter and the motor.
If required, line inductors are typically installed in a shielded caged enclosure at the soft starter end of the motor
cable.
To find out if line inductors are required for your specific installation, contact your local supplier for advice. You will
need to provide information about the motor output cable, including the cable length, cable type, and cable inductance
and capacitance per km.

INSTALLATION
Power Factor Correction
CAUTION
Power factor correction must be switched in using a dedicated contactor. Installing power factor correction
capacitors with no contactor may damage the soft starter.
Power factor correction capacitors should be selected based on the motor data and the required final power factor.
Select a contactor according to the required kVAr.
The soft starter must control the power factor correction capacitor contactor. Use the PFC output (terminals 33, 34 on
the power interface board).

CAUTION
Capacitive surge arrestors may be mounted in the motor termination box. Check the motor datasheet and
check inside the termination box before connecting the soft starter. Disconnect any capacitive surge
arrestors.

5.4 Operation mode selector switch (S1)
The MVE can soft start the motor, or can DOL start the motor with or without protection. Use the operation mode
selector switch (S1) to select the start mode.
SST position (soft start)
•The customer's external control signals start and stop the motor.
•The MVE performs a normal soft start.
•All soft starter protections are active.
•Relay outputs on the soft starter's power interface board control the line, bypass and PFC contactors.
DOL+ position (DOL with protection)
•The customer's external control signals start and stop the motor.
•The line and bypass contactors start the motor DOL.
•All soft starter protections are active.
•Relay outputs on the soft starter's power interface board control the line, bypass and PFC contactors.
NOTE
This mode allows the motor to be started when there is a fault with one of the soft starter phase arms. The
controller and power interface board must be in healthy working state.
DOL position (DOL without protection)
•The customer's external control signals start and stop the motor.
•The line and bypass contactors start the motor DOL.
•All soft starter protections are bypassed.
•The line and bypass contactors are controlled by the start and stop control signals.
•The PFC contactor (if used) must be controlled by a separate manual switch.
NOTE
This mode allows emergency operation of the motor when there is a major failure of any soft starter
component. Back-up fuses provide short circuit protection. Additional protections such as motor protection
or RTD overtemperature may be available if separate protection equipment is installed.
