ABB PSE18 Manuel page 8

Capacitors for power factor compensation are not allowed between
the softstarter and the motor, since this can cause current peaks which
can damage the thyristors in the softstarter. If such capacitors are to be
used, they should be connected on the line side of the softstarter.
3. Connect control supply voltage to terminals 1 and 2.
4. Connect terminal 14 to the functional earth.
The earthing is not a protective earth, it is a functional earth. The
earthing cable should be as short as possible. Maximum length 0.5 m.
The earthing cable should be connected to the mounting plate, which
should also be earthed.
5. Connect the start, stop and other control circuits including the analog
out to the terminals, 8, 9, 10, 11, 12, 13 and 14 if needed. This section
is using an internal 24 V DC. Do not feed with any external voltage.
Do not connect an external voltage to the control terminals 8, 9, 10, 11,
12, 13 and 14. Failure to observe the above may damage the softs-
tarter and the warranty may no longer be valid.
6. Connect terminals 3, 4, 5, 6 and 7 when using the signal output relays.
These are potential free contacts for maximum 250 V AC, 1,5 A AC-15.
Make sure you are using the same voltage level within this terminal
section.
The same external voltage (maximum 24 V DC or maximum 250 V AC)
must be connected to the output relay terminals 3, 4, 5, 6 and 7. Failure
to observe the above may damage the softstarter and the warranty may
no longer be valid.
