The frame connection to the PDU chassis

must be made to the same panel that has the

grounded stud.

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

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

On PDU chassis, there is a dedicated nut
for incoming ground wire connection to
chassis stud.

CB100 = 30 rating. TBD delay curve

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

Logic PS fuse = 3AB, 250V, 15A, standard
delay curve
Array PS fuse = 3AG, 250V, 6.3A, slow-blow
delay curve

Only one phase is fused in AUX PS.

Ground connections to IEC-320 connectors in
power strips are double crimped
#16 AWG IN 0.250 fast-on tab connectors.
