Notes

1The frame connection to the PDU chassis must be made to the same panel that has the grounded stud.

2The array and logic DPCS’s are safety grounded through the input AC connector.

3There may be metal-metal contact between DCPS chassis and machine frame. Frame which is not controlled and can not serve as a safety ground.

4On PDU chassis, there is a dedicated nut

for incoming ground wire connection to chassis stud.

5CB100 = 30 rating. TBD delay curve

6Both phases are fused in logic and array PS’s.

7Logic PS fuse = 3AB, 250V, 15A, standard delay curve

Array PS fuse = 3AG, 250V, 6.3A, slow-blow delay curve

8Only one phase is fused in AUX PS.

9Ground connections to IEC-320 connectors in power strips are double crimped

#16 AWG IN 0.250 fast-on tab connectors.
