Contains most of the electronics and power supplies
Located on the right end of the TS3244 (TS3, TS3/8)
Located on the left end of the TS3244 (TS8)
TS8 machines are auto configuring (or wide ranging). The unit has a voltage
range of 200-240 V (including tolerances the voltage range is 180-264).
Therefore, NO jumpers are required.
For TS3, the voltage rating is 200-208 / 220 / 230-240 V, with jumper
settings on a DIN rail, and on terminal blocks in the last design ~SN60+. For
more some quite ancient info on TS3, see Power
Distribution .
