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.
