2.2 Unexpected Operation
WARNING – ACCIDENTAL STARTS
In some installations, accidental starts may pose an increased risk to safety
of personnel or damage to the machines being driven. In such cases, it is
recommended that the power supply to the soft starter is fitted with an
isolating switch and a circuit-breaking device (eg power contactor)
controllable through an external safety system (eg emergency stop, fault
detector).
WARNING – STARTER MAY START OR STOP UNEXPECTEDLY
The VersiStart p III will respond to control commands from various sources,
and could start or stop unexpectedly. Always disconnect the soft starter from
mains voltage before accessing the starter or load.
WARNING – DISCONNECT MAINS BEFORE ACCESSING STARTER OR
LOAD
The soft starter has built-in protections which can trip the starter in the event
of faults and thus stop the motor. Voltage fluctuations, power cuts and motor
jams may also cause the motor to trip.
The motor could restart after the causes of shutdown are rectified, which
may be dangerous for personnel. Always disconnect the soft starter from
mains voltage before accessing the starter or load.
CAUTION – MECHANICAL DAMAGE FROM UNEXPECTED RESTART
The motor could restart after the causes of shutdown are rectified, which
may be dangerous for certain machines or installations. In such cases, it
is essential that appropriate arrangements are made against restarting
after unscheduled stops of the motor.

2.3 Avertissements à l'attention des clients canadiens
AVERTISSEMENT
L'icône AVERTISSEMENT ci-contre signale les informations concernant des
risques pouvant entraîner des blessures graves, voire mortelles. Pour votre
sécurité, veuillez consulter les avertissements sur cette page ou demander
une copie du présent manuel en français auprès de votre distributeur local.
AVERTISSEMENT – RISQUE DE CHOC ÉLECTRIQUE
Les zones suivantes sont soumises à des tensions pouvant provoquer des
risques de chocs électriques graves, voire mortels :
Raccordement et câbles d'alimentation AC
Câbles et raccordements de sortie
De nombreuses pièces internes du démarreur
PAR SÉCURITÉ
La fonction STOP du démarreur progressif n'isole pas des tensions
dangereuses de la sortie du démarreur. Le démarreur progressif doit être
déconnecté par un dispositif d'isolement électrique approprié avant
d'accéder aux connexions électriques.
Les fonctions de protection du démarreur progressif ne concernent que
la protection du moteur. Il relève de la responsabilité de l'utilisateur
d'assurer la sécurité des personnes travaillant sur les machines.
Le démarreur progressif est un appareil conçu pour s'intégrer dans un
système électrique ; il relève donc de la responsabilité du concepteur ou
de l'utilisateur de veiller à ce que ce système soit sûr et conçu selon les
normes de sécurité locales en vigueur.
AVERTISSEMENT – DÉMARRAGES ACCIDENTELS
Dans certaines installations, des démarrages accidentels peuvent
provoquer un risque supplémentaire pour la sécurité des personnes ou
endommager les machines contrôlées. Dans de tels cas, il est
recommandé de doter l'alimentation du démarreur progressif d'un
interrupteur d'isolement et d'un coupe-circuit (par exemple, un disjoncteur)
contrôlable à partir d'un système de sécurité externe (par exemple, un
arrêt d'urgence, un détecteur de défaut).
AVERTISSEMENT – LE DÉMARREUR PEUT DÉMARRER OU
S'ARRÊTER À TOUT MOMENT
Le démarreur progressif répond aux commandes de contrôle de différentes
origines et peut par conséquent démarrer ou s'arrêter à tout moment.
Toujours déconnecter le démarreur de la tension secteur avant d'accéder au
démarreur ou à la charge.

VersiStart p III
8
AVERTISSEMENT – DÉCONNECTER L'ALIMENTATION PRINCIPALE
AVANT D'ACCÉDER AU DÉMARREUR OU À LA CHARGE
Le démarreur progressif comporte des protections intégrées qui peuvent
déclencher des mises en sécurité dans l'éventualité de défauts et ainsi
arrêter le moteur. Des fluctuations de tension, des coupures d'alimentation et
des blocages du moteur peuvent produire des mises en sécurité de celui-ci.
Le moteur pourrait redémarrer une fois que les causes de l'arrêt ont été
résolues, ce qui pourrait mettre en danger le personnel. Toujours
déconnecter le démarreur de la tension secteur avant d'accéder au
démarreur ou à la charge.
AVERTISSEMENT
Ne pas appliquer la tension du secteur au démarreur tant que tout le
câblage n'est pas terminé.
AVERTISSEMENT
Toujours appliquer la tension de commande avant (ou en même temps que)
la tension secteur.
AVERTISSEMENT
Lors du raccordement du VersiStart p III en connexion 6 fils, toujours
installer un contacteur principal ou un disjoncteur magnéto-thermique à
bobine de déclenchement.
AVERTISSEMENT
Si l'entrée de démarrage est fermée lorsque la tension de commande est
appliquée, le démarreur tentera d'effectuer un démarrage.
Vérifier que l'entrée de démarrage/arrêt est ouverte avant d'appliquer la
tension de commande.

3 Declaration of conformity
In industrial linguistic usage the drive controllers of the type series VersiStart p III
are called "devices", however, in the sense of the "law on the safety of equipment",
the "EMC-law" or the "EC-machinery directive" they are not devices or machines
ready for use or connection but they are components. It is only possible to define
their final function, when these components are integrated into the design and
construction of the user.
To be able to use the devices to their intended purpose, it requires power
supply networks according to DIN EN 50160 (IEC 60038).
The user takes the responsibility that the user's design and construction comply
with the applicable legal provisions.
The commissioning is strictly forbidden as long as the conformity of the final system
with the guidelines 2006/42/EC (Machinery directive) and 2014/35/EU (Low voltage
directive) is not proved.
The devices of the VersiStart p III series are electrical equipment that is used in
industrial electrical power installations. They are designed for application in
machines, in order to reduce the starting torque and starting current peaks as well
as the tripping torque of drives with three-phase induction motors. With due regard
to the installation guidelines they meet the following requirements:
Emitted interference: Continuous duty EN 61000-6-3:2005
Acceleration, deceleration EN 60947-4-2
Immunity to interference: EN 61000-6-2:2005
VersiStart p III has been designed to meet the standards specified in EN 60947-4-2:
Low voltage switchgear – Part 4-2 Contactors and motor-starters – AC
Semiconductor motor controllers and starters, for low voltage safety, operation and
EMC.
This product has been designed as Class B equipment. Use of this product in
domestic environments may cause radio interference, in which case the user may
be required to employ additional mitigation methods.

4.3 Model Selection
Starter sizing
The soft starter must be the correct size for the motor and the application.
Select a soft starter that has a current rating at least equal to the motor's full load
current (nameplate) rating, at the start duty.
The soft starter's current rating determines the maximum motor size it can be used
with. The soft starter's rating depends on the number of starts per hour, the length
and current level of the start, and the amount of time the soft starter will be off (not
passing current) between starts.
The soft starter's current rating is only valid when used in the conditions specified in
the AC53b code - the soft starter may have a higher or lower current rating in
different operating conditions.

Finger Guard Kit
Finger guards may be specified for personnel safety. Finger guards fit over the soft
starter terminals to prevent accidental contact with live terminals. Finger guards
provide IP20 protection when used with cable of diameter 22 mm or greater.
Finger guards are compatible with models VS p 184 ~ VS p 580.
Soft Starter Management Software
PC software can provide real-time or offline management of soft starters.
•For real-time management in a network of up to 254 starters, the software
must connect to the soft starter via a Modbus TCP or Modbus RTU card. The
software can monitor, control and program the starter across the network.
•The software can be used to program the starter via the USB port on the
pumping smart card.
•For offline management, a configuration file generated in the software can be
loaded into the starter via the USB port.
4.8 Main Contactor
A main contactor is recommended to protect the soft starter from voltage
disturbances on the network, while stopped. Select a contactor with an AC3 rating
greater than or equal to the full load current rating of the connected motor.
Use the main contactor output (33, 34) to control the contactor.
WARNING
When connecting the VersiStart p III in inside delta configuration, always
install a main contactor or shunt trip circuit breaker.
4.9 Circuit Breaker
A shunt trip circuit breaker may be used instead of a main contactor to isolate the
motor circuit in the event of a soft starter trip. The shunt trip mechanism must be
powered from the supply side of the circuit breaker or from a separate control
supply.

4.10 Power Factor Correction
If power factor correction is used, a dedicated contactor should be used to switch in
the capacitors.
To use the VersiStart p III to control power factor correction, connect the PFC
contactor to a programmable relay set to Run. When the motor reaches full speed,
the relay will close and power factor correction will be switched in. Do not use the
soft starter relay output to directly switch in power factor correction.

CAUTION
Power factor correction capacitors must be connected to the input side of the
soft starter. Connecting power factor correction capacitors to the output side
will damage the soft starter.
4.11 Short Circuit Protection Devices (SCPD)
Fuses may be installed to protect the soft starter or the installation.
Type 1 Coordination
Type 1 coordination requires that, in the event of a short circuit on the output side of
a soft starter, the fault must be cleared without risk of injury to personnel. There is
no requirement that the soft starter must remain operational after the fault.
HRC fuses (such as Ferraz/Mersen AJT fuses) can be used for Type 1 coordination
according to IEC 60947-4-2 standard.
Type 2 Coordination
Type 2 coordination requires that in the event of a short circuit on the output side of
a soft starter, the fault must be cleared without risk of injury to personnel or damage
to the soft starter.
Semiconductor fuses for Type 2 circuit protection are additional to HRC fuses or
MCCBs that form part of the motor branch circuit protection.
CAUTION
DC Brake: A high brake torque setting can result in peak currents up to
motor DOL being drawn while the motor is stopping. Ensure protection
fuses installed in the motor branch circuit are selected appropriately.

CAUTION
Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with
the National Electrical Code and any additional local codes.
