CAUTION STATEMENTS
710-14888-00C EMX4i User Manual 5
GROUNDING AND BRANCH CIRCUIT PROTECTION
It is the responsibility of the user or person installing the EMX4i to provide
proper grounding and branch circuit protection according to local electrical
safety codes.
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 EMX4i 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.
