2 Safety
2.1 Safety Symbols
The following symbols are used in this manual:
DANGER
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
NOTICE
Indicates a property damage message.
2.2 Qualified Personnel
Correct and reliable transport, storage, installation, operation, and maintenance are required for the trouble-free and safe operation
of the soft starter. Only qualified personnel are allowed to install or operate this equipment.
Qualified personnel are defined as trained staff, who are authorized to install, commission, and maintain equipment, systems, and
circuits in accordance with pertinent laws and regulations. Also, the qualifed personnel must be familiar with the instructions and
safety measures described in this manual.
2.3 Safety Precautions
Safety precautions 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 before installing, operating, or maintaining the equipment.
Follow good electrical practice including applying appropriate personal protective equipment.
Seek advice before operating this equipment in a manner other than described in this manual.
NOTICE
The VLT® Soft Starter MCD 600 is not user serviceable. The unit should only be serviced by authorized service personnel. Unau-
thorized tampering with the unit voids the product warranty.
WARNING
PROPER GROUNDING
It is the responsibility of the installer of the soft starter to provide proper grounding and branch circuit protection according to
local electrical safety codes. Not providing proper grounding and branch circuit protection may lead to death, personal injury, or
equipment damage.
Disconnect the soft starter from mains voltage before carrying out repair work.

WARNING
UNINTENDED START
When the soft starter is connected to AC mains, DC supply, or load sharing, the motor can start at any time. Unintended start
during programming, service, or repair work can result in death, serious injury or property damage. The motor can start with an
external switch, a fieldbus command, an input reference signal from the LCP, or after a cleared fault condition.
Press [Off/Reset] on the LCP before programming parameters.
Disconnect the soft starter from the mains.
Completely wire and assemble the soft starter, motor, and any driven equipment before connecting the soft starter to AC
mains, DC supply, or load sharing.
Fit the power supply to the soft starter with an isolating switch and a circuit-breaking device (for example a power contactor)
controllable through an external safety system (for example an emergency stop or a fault detector).
CAUTION
POWER FACTOR CORRECTION
Connecting power factor correction capacitors to the output side will damage the soft starter.
Do not connect power factor correction capacitors to the output of the soft starter. If static power factor correction is em-
ployed, it must be connected to the supply side of the soft starter.
CAUTION
SHORT CIRCUIT
The VLT® Soft Starter MCD 600 is not circuit proof.
After severe overload or short circuit, the operation of the MCD 600 should be fully tested by an authorized service agent.
CAUTION
MECHANICAL DAMAGE FROM UNEXPECTED RESTART
The motor could restart after the causes of a shutdown are rectified, which may be dangerous for certain machines or installa-
tions.
Ensure that appropriate arrangements are made against restarting after unscheduled stops of the motor.
WARNING
SAFETY OF PERSONNEL
The soft starter is not a safety device and does not provide electrical isolation or disconnection from the supply.
If isolation is required, the soft starter must be installed with a main contactor.
Do not rely on the start and stop functions for safety of personnel. Faults occurring in the mains supply, the motor connec-
tion, or the electronics of the soft starter can cause motor starts or stops.
If faults occur in the electronics of the soft starter, a stopped motor may start. A temporary fault in the mains supply or loss of
motor connection can also cause a stopped motor to start.
To provide safety of personnel and equipment, control the isolation device through an external safety system.
NOTICE
Before changing any parameter settings, save the current parameter set to a file using MCD PC Software or the Save User Set
function.

3.3 Selection of Soft Starter Size
The size of the soft starter must match the motor and the application.
Select a soft starter that has a current rating at least equal to the motor's full load current rating (see motor nameplate) 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 is off (not passing cur-
rent) between starts.
The soft starter's current rating is only valid when used in the conditions specified in the AC53 code. The soft starter may have a
higher or lower current rating in different operating conditions.
