NOTE
The EMX4e is not user serviceable. The unit should only be serviced by
authorised service personnel. Unauthorised tampering with the unit will void
the product warranty.
FOR YOUR SAFETY
•The STOP function of the soft starter does not isolate dangerous
voltages from the output of the starter. The soft starter must be
disconnected by an approved electrical isolation device before accessing
electrical connections.
•Soft starter protection features apply to motor protection only. It is the
user’s responsibility to ensure safety of personnel operating machinery.
•The soft starter is a component designed for integration within an
electrical system; it is therefore the responsibility of the system
designer/user to ensure the system is safe and designed to comply with
relevant local safety standards.
2.1 Electrical shock risk
WARNING – ELECTRICAL SHOCK RISK
The voltages present in the following locations can cause severe electric
shock and may be lethal:
•AC supply cables and connections
•Output cables and connections
•Many internal parts of the starter
SHORT CIRCUIT
The EMX4e is not short circuit proof. After severe overload or short circuit,
the operation of the EMX4e 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 EMX4e to provide
proper grounding and branch circuit protection according to local electrical
safety codes.
4EMX4e User Manual 710-21918-00A

CAUTION STATEMENTS
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 EMX4e 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.

CAUTION STATEMENTS
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
L’EMX4e 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.
6EMX4e User Manual 710-21918-00A

CAUTION STATEMENTS
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
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.

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.

EMX4e starters can be used with a remote keypad, mounted up to 3 metres away
from the starter. Each expansion card includes a keypad connection port, or a
dedicated keypad connector card is available.
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 EMX4e-0184B ~ EMX4e-0580B.
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.
3.8 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.
3.9 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.
14 EMX4e User Manual 710-21918-00A

SYSTEM DESIGN
3.10 Power Factor Correction
If power factor correction is used, a dedicated contactor should be used to switch in
the capacitors.
To use the EMX4e 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.

Fuses may be installed to protect the soft starter or the installation.

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
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.
