There is one AC power cord receptacle located at the rear of the 7450 ESS-1AC/DC
model chassis.
The power supply operates with a nominal utility system voltage of 100V to 240V, but
will operate with input voltages ranging from 85 to 264 VAC.
A fully redundant system operates with two power systems. AC and DC power types are
available in the 7450 ESS-1 chassis.
→ AC/DC model — Plug an AC power cord into the AC receptacle at the rear of the
chassis. Wire the single DC terminal block on the AC/DC model.
→ DC/DC model — Wire both DC terminal blocks on the DC/DC model.
An AC power cord is shipped with each 7450 ESS-1 AC/DC model unit.
The chassis has a AC plug receptacle to accept an AC power cord. The other end of the
AC power cord must have a plug that fits into the power source receptacle that is standard
for your geographic region.
