1.1 Safety
1.1.1 Warnings
When reading this manual you will come across different symbols that require special attention. The symbols used are the following:
NB!
Indicates something to be noted by the reader
Indicates a general warning
Indicates a high voltage warning
The examples and diagrams in this manual are included solely for illustrative purposes. The information contained in this manual is subject to change at
any time and without prior notice. In no event will responsibility or liability be accepted for direct, indirect or consequential damages resulting from the
use or application of this equipment.
WARNING - ELECTRICAL SHOCK HAZARD
MCD 500 soft starters contain dangerous voltages when connected to mains voltage. Only a competent electrician should carry out the
electrical installation. Improper installation of the motor or the soft starter may cause equipment failure, serious injury or death. Follow
this manual and local electrical safety codes.
Disconnect the soft starter from mains voltage before carrying out repair work.
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.
Do not connect power factor correction capacitors to the output of MCD 500 soft starters. If static power factor correction is employed,
it must be connected to the supply side of the soft starter.
The motor can be stopped by means of digital or bus commands while the soft starter is connected to the mains, if the soft starter is in Auto On mode.
1. If personal safety considerations make it necessary to ensure that no unintended start occurs,
these stop functions are not sufficient.
2. A motor that has been stopped may start if faults occur in the electronics of the soft starter, or a temporary fault in the supply mains or the
motor connection ceases.
AUTO-START
Use the auto-start feature with caution. Read all the notes related to auto-start before operation.

Equipment containing electrical components may not be disposed of together with domestic
waste.
It must be collected separately as electrical and electronic waste according to local and cur-
rently valid legislation.
