Delta Tau 3Ax-602646-xUxx User Manual

 

Connect desired main input power to input terminals marked L1, L2, and L3 (see Figure 7).  The power 
ground can be connected at the terminal marked CHAS GND or at the grounding screw, marked E, located 
on the end panel of the Quad Amplifier chassis.  The main input power terminals are rated for 600V and 85 
Amps. 

Connect single-phase input power to pins 1 and 2 of AC input connector C3 marked CONTROL AC 
INPUT PWR, located on the top panel of the Quad Amplifier (see Figure 7).  Pin 4 of connector C3 is used 
for ground (green wire).  If the input power requirements have changed since the Quad Amplifier order, the 
Control Power Transformer  (T201), located under the Quad Amplifier cover, must be reconfigured for 
proper operation (see Figures 7 and 8). 

Control AC Input voltage is factory set in accordance with the ordering information.   

For 120VAC Operation 

Jump pin 1 to pin 5 and jump pin 2 to pin 6.  Power is applied to pins 1 and 2 via AC input connector C3. 

For 208VAC Operation 

Jump pin 1 to pin 5 and jump pin 3 to pin 7.  Power is applied to pins 1 and 3 via AC input connector C3. 

For 230VAC Operation  

Jump pin 1 to pin 5 and jump pin 4 to pin 8.  Power is applied to pins 1 and 4 via AC input connector C3. 

For 380 VAC Operation 

Jump pin 4 to pin 5 and pin 6 to pin 9. Power is applied to pins 1 and 10 via AC input connector C3.
