2-5 SERIES C R-FRAME, SPB AND DSII/DSLII
OPTIM TRIP UNITS
Model 750 and 1050 OPTIM Trip Units used in Series C
R-Frame, SPB Systems Pow-R and DSII/DSLII circuit
breakers are field replaceable. Model 550 is only avail-
able on the R-Frame circuit breaker. For each of these
circuit breaker types, rating plugs are used to select the
continuous ampere rating of the circuit breaker. The rat-
ing plugs and circuit breakers are keyed with a mechani-
cal interlock to prevent incorrect installation. The contin-
uous ampere rating of each of these circuit breakers is
adjustable via the rating plugs as follows:
• Series C R-Frame (800-2500 amperes) (Figure
2-7
)
• SPB Pow-R (200-5000 amperes) (Figure
2-8
)
• DSII/DSLII (100-5000 amperes) (Figure
2-9
)
Refer to Table
2.1
for the available rating plug values by
circuit breaker type.
Unit Status LED
The green Unit Status LED blinks with a one second on-
off duty cycle when power is applied to the trip unit and
it is functioning properly.
INCOM Transmit LED
The red transmit LED flashes red when the trip unit is
communicating over an INCOM network.
Programming Port
A custom phone type jack programming port is located
with the trip indicator battery behind the small access
cover. One end of the custom phone type cord provided
with the OPTIMizer Hand Held Programmer plugs into
the port, and permits direct programming of the trip unit
(Figure
2-6
). To access the programming port, remove
the access cover by pulling down on the release tab
located in the center of the cover while pulling out on the
cover. The port will accept either end of the custom
phone cord.
Notice:
When the OPTIMizer is plugged into a trip
unit, it prevents all remote IMPACC communi-
cations (if present) with that trip unit. This
action will also cause a No-Response alarm
on the Breaker Interface Module and a master
network. Refer to Instruction Book 29C892
