2.4 Power connection
The power section should be protected according to the connection form
used.
Cable and device protection on the supply side:
•
Input AC… via standard fuses for cable protection or via motor-protective
circuit-breaker.
•
Fuses in UL compliant systems must be UL-approved.
•
The rated operating voltages of the fuses must be suitable for the local
mains voltage.
•
No fuses are required on the motor side.
The following figure shows the basic connection of motor and power
section.

F3 = optional semiconductor fuse
Q1 = Cable prot motor protection
Q21 = Soft starter
M1 = Motor
At the output of the soft starter (terminals 2T1, 4T2, 6T3) you must not
•
Connect any capacitive load (e.g. phase compensation capacitors),
•
Connect several soft starters in parallel,
•
Feed a mains voltage or a voltage from a variable frequency drive or other
voltage source.
