6 Only qualified personnel are allowed to install or operate this personnel are defined as trained staff, who are authorized to install, commission, and maintain equipment, systems, andcircuits in accordance with pertinent laws and regulations. Also, the qualifed personnel must be familiar with the instructions andsafety measures described in this Safety PrecautionsSafety precautions cannot cover every potential cause of equipment damage, but can highlight common causes of damage. It is theinstaller's responsibility to:Read and understand all instructions in this manual before installing, Operating , or maintaining the good electrical practice including applying appropriate personal protective advice before Operating this equipment in a manner other than described in this O T I C EThe VLT soft Starter MCD 600 is not user serviceable. The unit should only be serviced by authorized service personnel.

7 Unau-thorized tampering with the unit voids the product A R N I N GPROPER GROUNDINGIt is the responsibility of the installer of the soft Starter to provide proper grounding and branch circuit protection according tolocal electrical safety codes. Not providing proper grounding and branch circuit protection may lead to death, personal injury, orequipment the soft Starter from mains voltage before carrying out repair / 175R1174 | 9 Danfoss A/S soft Starter MCD 600 Operating Guide ------------W A R N I N GUNINTENDED STARTWhen the soft Starter is connected to AC mains, DC supply, or load sharing, the motor can start at any time. Unintended startduring programming, service, or repair work can result in death, serious injury or property damage. The motor can start with anexternal switch, a fieldbus command, an input reference signal from the LCP, or after a cleared fault [Off/Reset] on the LCP before programming the soft Starter from the wire and assemble the soft Starter , motor, and any driven equipment before connecting the soft Starter to ACmains, DC supply, or load 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).

If static power factor correction is em-ployed, it must be connected to the supply side of the soft A U T I O NSHORT CIRCUITThe VLT soft Starter MCD 600 is not circuit severe overload or short circuit, the operation of the MCD 600 should be fully tested by an authorized service A U T I O NMECHANICAL DAMAGE FROM UNEXPECTED RESTARTThe motor could restart after the causes of a shutdown are rectified, which may be dangerous for certain machines or that appropriate arrangements are made against restarting after unscheduled stops of the A R N I N GSAFETY OF PERSONNELThe soft Starter is not a safety device and does not provide electrical isolation or disconnection from the isolation is required, the soft Starter must be installed with a main not rely on the start and stop functions for safety of personnel.

9 Faults occurring in the mains supply, the motor connec-tion, or the electronics of the soft Starter can cause motor starts or faults occur in the electronics of the soft Starter , a stopped motor may start. A temporary fault in the mains supply or loss ofmotor connection can also cause a stopped motor to provide safety of personnel and equipment, control the isolation device through an external safety O T I C EBefore changing any parameter settings, save the current parameter set to a file using MCD PC Software or the Save User / 175R117410 | Danfoss A/S soft Starter MCD 600 Operating Guide -N O T I C EUse the Auto-start feature with caution.
