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.
NOTE
The soft starter 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 HAZARD
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 soft starter is not short circuit proof. After severe overload or short circuit, the
operation of the soft starter 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 soft starter 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).
