Note
Contactor K3 is required for the 'Op-
eration in Bypass Power Circuit' and
is controlled by the programmable
relay set as a 'Top of Ramp' relay.
The
Electronic control card
is located underneath
the cover in the all units.
Connections shown in the control circuit wiring diagram
are made to the electronic control card terminals as
shown in fig.2.2 below.

For this
configuration,
applying the
equation,
I

(XFE)
allows lower current
rating XFE than
the motor.

Wiring Diagrams
Use the control circuit with one of these power circuits
Note 1:
Correction capacitors:
Power factor correction capacitors must
NOT
be positioned on the output of the power circuit.
Note 2:
Fuse Selection:
Where semiconductor type fuses are required, they should be selected from the table in Section 5.
Note 3:
The in-line configuration shown in Fig 2.3 requires that the firing mode be set to ‘0’.
Note 4:
The
In-Delta configuration
as in Fig 2.4 requires that the Firing Mode be set to
‘1’.
An in-line contactor controlled by the XFE
MUST
be used with the In-Delta firing mode.
Note 5:
The
bypass configuration
as in Fig 2.5 is automatically detected as “Auto bypass” is set as default.
