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.
NOTE
The EMX3 is not user serviceable. The unit should only be serviced by authorised service personnel. Unauthorised
tampering with the unit will void the product warranty.
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
The AC supply must be disconnected from the starter using an approved isolation device before any cover is removed from
the starter or before any servicing work is performed.
WARNING - ELECTRICAL SHOCK HAZARD
Models EMX3-0500B~EMX3-1600C: The busbar and heatsink must be treated as live whenever the unit has mains voltage
connected (including when the starter is tripped or waiting for a command).
SHORT CIRCUIT
The EMX3 is not short circuit proof. After severe overload or short circuit, the operation of the EMX3 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 EMX3 to provide proper grounding and branch circuit protection
according to local electrical safety codes.
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.
2.2
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 EMX3 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.
AUTO-START
Use the auto-start feature with caution. Read all the notes related to auto-start before operation.
