1 3. 1 .2 RMS-9 & EPIC MICROVERSATRIP®
INSTALLATION
The programmer mounts to the upper left of the breaker
as shown in Fig. 1 00. It mounts to the bracket assem bly
shown in Fig.
82.
Referring to Fig.
82,
the guide p ins mate
with the hole on either side of the programmer connector.
They provide the n ecessary alignment for the connector
engagement. The locking lever engages with the pin which
is assemb led to the programmer frame and secures the
programmer to the mounting bracket.
Installation .is as follows:
a. I nsert the guide pins into the holes and push on the
programmer, engaging the connectors.
b. The locking lever is released, securing the program
mer.
c. Verify that the locking lever did engage the program
mer pin.
To remove the programmer:
a. Pull out locking lever, which will release the program
mer pin. Remove the programmer.
1 3.2 CURRENT SENSORS
The current sensors supply the power and signal input
necessary to o perate the tri p system .
Like the
M icroVersaTrip"', the RMS-9 and Epic MicroVersaTrip '
uses a phase and neutral sensor. Fig. 1 01 shows the
phase sensors. See Section 1 3.5 for cabling d iagrams.
FIG. 1 00 - AKR-70-30
The fixed phase sensors have a polarity associated with
their windings. Their COM MON terminal is the right hand
termi nal as shown in Fig. 1 01 . A white wire with a terminal
will be connected to this COMMON terminal. All phase
sensors must be correctly wired for the programmer
summing circuit to function properly.
The phase sensors are available with an additional
winding. This winding is brought out to separate flag
terminals. These phase sensors are used when the hi
level instantaneous RMS-9 option (
'
H '-option) is required .
Fig. 1 02 shows an ' H ' -option phase sensor. When the
' H ' -option phase sensor is i nstalled , there are four leads
connected to it. There is no polarity associated with the
special winding connection . Fig . 1 0 2 shows the connec
tions for the additional ' H ' -option windings.
