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
employed, 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
installations.
-Ensure that appropriate arrangements are made against restarting after unscheduled stops of the motor.
