Optima 820 Series
4 Reference
Standard Features
(1) Main Power breaker and indicator. The breaker
will have a 15, 20, or 30 A maximum-duty rating
(de-rated to 80% for continuous duty). Indicator is
amber. Whenever the main circuit breaker is On,
the Powered indicator is illuminated to indicate that
power is
available
to the switched outlets. Outlets
themselves may not be on.
(2) Front-panel unswitched outlet. This outlet is always
powered when the main breaker is on—that is, it is
never switched or disabled by EPO even when those
options are included. Power is disabled when the
main breaker is off.
(3) Rear-panel switched outlets. These outlets are
controlled by the RCM switching software. All outlets
are disabled by remote EPO
when that option is
included
and the software state is updated to reflect
the off status of the outlets.
(4) Threaded ground lug.
(5) Power inlet. Most models include a strain-relieved
cable as shown. The plug will vary by model. Some
models include a panel-mounted C20 connector.
(6) Circuit breaker for internal control circuitry.
(7) Ethernet, RS-232 serial console, and auxilary
connections. All are RJ-45. Auxilary connectors are
for Marway Temperature/Humidity sensors.
(8) Mounting brackets. May be mounted in one of
three locations to yield a “flush,” recessed, or rear-
facing position of the chassis relative to the rack’s
mounting flanges. May also be removed for table top
operation, or adaptation of end user’s own custom
brackets.
Optional Features
(9) Optional display when the power monitoring option
is included (all “PSW” models). Displays volts, amps,
watts, VA, VAR, power factor, and frequency. When
item 9 is included, item 10 is also included.
(10) Optional display keypad used to navigate values
available on the display.
(11) Optional Remote EPO mode switch to control remote
EPO panel influence. When item 11 is included, item
12 is also included.
(12) Optional Remote EPO control bus interface for
interfacing to a Marway UCP.
