ATTENTION!
The connection of the motor to the Soft-Starter must be made
carefully. Follow strictly the connection diagrams according
to the winding types shown in Figure 3.5 and item 6.4.1.
If reversal of motor direction of rotation is required, change
the Soft-Starter connection to the network only.
Ensure that the electronics is switched OFF while connec-
tions are changed each other.
Do not start motor with wrong P28 content:
OFF = standard connection
on = within the motor delta connection

relay
This function, when enabled, permits activates full
voltage indication by means of RL1 or RL2 (P51 or
P52) in order to energise a by-pass contactor.
The main function of the Soft-Starter By-Pass is
to eliminate the losses in the form of heat generated
by the Soft-Starter.
NOTE!
1) This function must always be programmed when a by-
pass contactor is used.
2) To keep the protections relating to motor current
reading, use external current transformers or the MAC-0x.
See section 10.
3) When P43 is set to "On", the parameters P74 and P76
become inactive "OFF".
