Three phase Designation
Please take extreme care when connecting the controller to the three-
phase supply. Incorrect connection may result in damage to the control-
ler.
The controller is normally supplied according to your requirements in
either a star or delta supply. However, some models may have a dual
supply option which accepts either Star or Delta 3-phase supply.

Filter Option
In countries where noise across power lines is a concern,
Mold-Masters recommends that you t the model 63AYC10B in-line
lter which is supplied by TC Connectivity
Star /Delta option
Where a cabinet is tted with a dual supply option then there are two
places within the rear of the cabinet that you must alter to change be-
tween Star and Delta supply.
Do not change the supply wiring until the controller has been discon-
nected from all electrical supplies.
At the upper connection blocks, change the Star/Delta cross-links using
a single 3-way link for Star supplies or three 2-way links for Delta
supplies. The connector strip shows the appropriate cross-links to use
and looks similar to this diagram.
At the base of the cabinet is the mains connector
strip that will accept a Star or Delta supply cable.
Use only 4-core supply cable for Delta connection
and 5-core supply cable for Star connection. Wire
this cable into the lower terminal as shown here.
