4.1.7 Motor Connection
MCD 500 soft starters can be connected to the motor in-line
or inside delta (also called three-wire and six-wire
connection). The MCD 500 will automatically detect the
motor connection and perform the necessary calculations
internally, so it is only necessary to program the motor full
load current (par. 1-1).
N
NOTE
For personnel safety, the power terminals on models up to
MCD5-0105B are protected by snap-off tabs. W
hen using
large cables, it may be necessary to break off these tabs.
Models which are internally bypass
ed do not require an
external bypass contactor.
