Control supply and control circuit
Wires in industrial control applications are divided into
three groups: main power supply, control supply and
control circuit.
Main power supply (1L1, 3L2, 5L3, 2T1, 4T2, 6T3)
Control supply voltage (terminals 1 and 2)
Control circuit (terminals 13 - 21).
3.2.1
Control supply voltage -
terminals 1 and 2
Connect neutral and phase to terminal 1 and 2.
See
Figure 4.
INFORMATION
Only use 100-250 V, 50 / 60 Hz supply voltage.

3.2.2
Functional earth - terminal 22
Softstarters type PSTX85...PSTX370 should be earthed
using the terminal 22 as shown in
Figure 5
(one
connection is sufficient). Connect the cable to an earthing
point close to the softstarter. The cable should be as
short as possible. A suitable earthing point is next to the
softstarter on the mounting plate, which should also be
earthed.
INFORMATION
This is not a protective earth, it is a function
earth. The earthing cable should be as short as
possible. Maximum length 0.5m.
INFORMATION
Do not use functional earth in IT-networks,
commonly found in for instance marine
applications.
