4.2.3 Commissioning examples
All SK 1x5E devices can basically be operated in the condition in which they are delivered.
If an automatic start-up is required when "Mains on" takes place (depending on setting
P130 ), either
adapt parameter ( P428 ) or set DIP switch S1-DIP1 = ON.
The PTC input must be bypassed, if a motor with PTC is not available.
The motor starter must be provided with an external 24 V DC control voltage.

Motor start via switch
Motor start with direction of rotation "right":
• If the switch is set to "On" and 24 V DC is therefore present at digital input 1 (terminal 21), the
motor starter starts to operate in the "right" (clockwise) direction.
Motor start with direction of rotation "left":
• If the switch is set to "On" and 24 V DC is therefore present at digital input 2 (terminal 22), the
motor starter starts to operate in the "left" (anticlockwise) direction.
Motor start via mains voltage "ON"
DIP switch S1 / DIP1 = ON corresponds to automatic start
Motor start with direction of rotation "right":
• If the mains voltage is set to "On" and 24 V DC is therefore present at digital input 1 (terminal 21),
the motor starter automatically starts to operate in the "right" (clockwise) direction.
Motor start with direction of rotation "left":
• If the mains voltage is set to "On" and 24 V DC is therefore present at digital input 2 (terminal 22),
the motor starter automatically starts to operate in the "left" (anticlockwise) direction.
