5.1.2 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)
Control supply voltage -
5.1.2.1
terminals 1 and 2
Connect neutral and phase to terminal 1 and 2.
See Figure 27.
Check that you have the correct supply voltage
U . See chapter 3.2.1 General.

5.1.2.2
Softstarters type PSTX85...PSTX370 should be earthed
using the terminals as shown in Figure 27 (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 Marine applications
and IT networks.
