Output 1 and 2 in Symmetrical Configuration.
1 Depending upon the desired output configuration the wiring
should be made as shown in fig. 17b, c, d or e.
2 Same conditions for both outputs.
3 If the output voltages are increased above Uo nom via R-input
control, option P setting, remote sensing or option T, the output
currents should be reduced accordingly so that
Po nom is not ex-
ceeded.
