<strong>DM</strong>4 soft <strong>starters</strong><br />
14/24<br />
Bypass circuit<br />
Engineering<br />
Connection examples<br />
After completion of the acceleration phase (full mains voltage reached), the soft<br />
starter M4 actuates the bypass contactor. This connects the motor directly with the<br />
mains.<br />

Advantage:<br />
• The soft starter’s heat dissipation is reduced to the heat dissipation at idle.<br />
• The limit values of radio interference class “B” are maintained.<br />
The bypass contactor is now switched into a zero-current state <strong>and</strong> can therefore be<br />
laid out to AC-1.<br />
If an EMERGENCY STOP requires an immediate isolation, the bypass contactor has<br />
to also switch the motor load <strong>and</strong> must therefore be laid out according to AC-3.<br />
