Wiring layout and connections
The cable entry for the unit is at the rear behind a removable cover-plate.
Always ensure that all the cables are secure and the length adequate.
The terminal block layout and wiring numbering is shown on the next page.
It can bee seen that the reserve and rectifier terminals are bridged.
If it is required to supply the unit from two different sources, simply remove the
bridging cables.
The phase rotation must always be clockwise
.
The labeling notation is as follows:
Rectifier input terminals:
1U1, 1V1, 1W1 & 1N1
Reserve input terminals: 2U1, 2V1 & 2W1
Output terminals:
U2, V2, W2 & N2
The earth connection is made to the earth stud under the wiring compartment.
