GFK-2362
January 2010
The RX7i rack can be used for all RX7i CPU and I/O
configurations, Series 90™-70 I/O, and VME
modules.
Backplane connectors are spaced on 0.8" (20.3mm)
centers to accommodate single-width RX7i modules,
VME modules, and single-width Series 90-70
modules. Double-width Series 90-70 modules use
two slots each.
The rack accepts a power supply in slot 0 and a
CPU in slot 1. The IC698CPE010/020 and
IC698CRE020 CPUs with Ethernet daughter card
are double-width modules and use slots 1and 2. The
remaining slots can be used for one of the following
I/O combinations:
Seven single-width modules (with no doublewidth modules installed),
Four double-width modules, or
A combination of double-width and single-width
modules.
For a list of supported modules, see the
PACSystems RX7i Installation Manual, GFK-2223.
The power supply capacity may limit the number of
modules in a rack.
Racks, 9-slot, Front and Rear Mount
Integration of VME modules must be in
accordance with guidelines which are described
in the RX7i User's Guide to Integration of VME
Modules, GFK-2235.
RX7i racks are considered open equipment, and
therefore must be installed in a protective
enclosure rated IP54 or greater.
Features
Provides slot sensing for rack-type I/O modules.
No jumpers or DIP switches on the I/O modules
are required for addressing of these modules.
Provides automatic daisy chaining of interrupt
acknowledge and bus grant signals so no blank
slot jumpers are required.
Provides J2 backplane connectors to allow highspeed VME transfers of up to 64 data bits per
cycle.
Accepts plug-in RX7i power supplies
Supports an optional cooling fan assembly
(required for IC698CPE020/CRE020).

Rack Mounting
for module cooling. Mounting requirements (front or
rear mount) must be determined according to the
application. Mounting flanges are an integral part of
rack side panels.
RX7i racks are considered open equipment, and
therefore must be installed in a protective
enclosure rated IP54 or greater.
Overall rack dimensions are 11.15"H x 12.6"W x
7.25"D (283 x 320 x 184mm). The following figures
show mounting dimensions for the rear mount and
front mount racks.
These racks accommodate two module types:
Rack-type RX7i and Series 90-70 single-width
I/O modules, which use a detachable field wiring
terminal board. Each I/O module accepts up to
2
forty AWG #14 (2.10 mm ) wires. The wire
bundle is routed out the bottom of the terminal
board cavity where a cleat is provided for a tie
wrap to secure the bundle to the terminal board
housing.
VME modules, which have varying methods of
connecting to field devices.
Note: If your installation includes a fan assembly,
a minimum clearance of 23cm (9 inches) between
RX7i racks is recommended so that an individual fan
can be removed and replaced.
The rear-mount rack mounts in a 10" (254 mm) deep
enclosure. The rack must be mounted in the
orientation shown in the following figures. Sufficient
space must be left around the rack to allow air flow

I/O point references for modules in an RX7i rack are
configured using the Machine Edition Logic
Developer-PLC software. For information on
configuration, see the software online help and the
Proficy™ Machine Edition Logic Developer-PLC
Getting Started manual, GFK-1918.
Shield Ground
RX7i Modules
The power supply, CPU, and all RX7i modules have
metal faceplates that are screwed directly to the
enclosure at the top and bottom to ensure the
faceplate is grounded to frame ground.
Series 90-70 Modules
Some Series 90-70 I/O modules have a ground clip
that contacts the conductive bottom rail when the

module is fully inserted. Shield connections in the
user connectors are routed to this ground clip
through conductors on the module.
Safety Ground
The #8-32 ground studs on the sides of the rack
must be connected to earth ground with not less
2
than an AWG #12 (3.33 mm ) wire. Use of a nut and
star washer for each wire on the GND stud is
recommended to ensure adequate grounding. Refer
to applicable electrical safety codes.
Warning
If the ground lug is not connected to earth
ground, the rack is not grounded. The rack
must be grounded to minimize electrical
shock hazard, which may result in severe
personal injury, and maintain certification
to standards.

System Noise Protection
The following steps must be taken to properly
ground the PLC system to reduce the possibility of
errors due to electrical noise.
1. Make sure that the power supply mounting
screws are properly secured.
2. The GND terminal on the power supply must be
connected to the GND terminal on either side of
2
the rack using AWG #12 (3.33 mm ) wire. Use of
a ring terminal and star washer is
recommended.
3. The GND terminal on the rack must be
connected to a reliable earth ground.
Note: RX7i modules use faceplates fitted with an
EMI gasket (a metal strip along the side of the
faceplate) to ensure contact of the gasket with the
faceplate of each adjacent module in the rack,
forming a continuous EMI shield for the modules in
the rack. (RX7i power supplies have the gasket on
both sides of the faceplate.) The EMI gasket should
be facing to the right when installed as one views
the front of the rack. This EMI shield makes the rack
less susceptible to external electrical noise and
minimizes the level of electrical noise radiated by the
rack. If the rack is not fully populated with gasketed
faceplates, it must be installed in a metal enclosure
to achieve similar noise improvement. Gasketed filler
faceplates may be ordered as needed.
(IC698ACC735 – single-width; IC698ACC720 double-width)
Module Retention
Series 90-70 double width I/O modules have molded
latches that automatically snap onto the upper and
lower rails of the rack when the module is fully
inserted. Some VME modules or Series 90-70 single
width modules may not have these latches.
RX7i modules are mechanically tied to frame ground
using screws that secure the top and bottom of the
faceplates to the enclosure. For high vibration
applications, other modules can be secured to the
rack using M2.5x8 screws.
To remove an RX7i or Series 90-70 module, first
remove the field half of the terminal board (if it is an
I/O module). If screws have been used to secure
modules to the rack, remove the screws. Then grasp
the top and bottom of the module to depress the
latch releases (CPU and Ethernet modules do not
have latches) while pulling the module out. For
detailed information on removing I/O terminal
boards, refer to the applicable Installation Manual or
individual data sheets for I/O modules.
Warning
Do not remove (or insert) modules when
the power supply or any externallyconnected power sources are on.
Hazardous voltages may exist. Personal
injury, damage to the module, or
unpredictable operation of the device or
process being controlled may result.
Insulating Strips for High Voltage Modules
The RX7i rack is shipped with an Insulator Kit that
includes enough parts to update three Series 90-70
I/O modules.
An insulator strip is required on a high voltage
module that is installed to the immediate right of a
module with a metal faceplate. Insulating strips
should be installed on the following modules that
have versions earlier than:
IC697MDL240D
IC697MDL241D
IC697MDL250G
IC697MDL251E
IC697MDL640E
IC697MDL340G
IC697MDL341E
IC697MDL350F
IC697BEM731W
IC697BEM713H
Note: Current versions of these modules are
shipped with the insulators installed. The strip is
visible on the back of the printed wiring assembly.
To install the insulating strip:
The plastic insulating strip is installed on the back
side of the printed wiring assembly, along the edge
of the I/O connector to prevent the possibility of high
voltage I/O cards short-circuiting to the metal
faceplates of VME cards. (Follow the installation
instructions included with the kit). Use part number
44A752213-G01 to order additional kits as
necessary.

Rack Fan Assembly
Rack Fan Assemblies are available in several
versions for forced air cooling when heat build-up
could be a problem.
Note:
A Rack Fan is required if the
IC698CPE020, IC698CRE020 or
IC698PSA350 is installed in the rack.
Three rack fan assemblies are available:
The following illustration shows the position of the
fan assembly mounted on a rack. It is mounted on
the bottom of the rack with air flow from the bottom
toward the top of the rack. When using the fan
assembly, filler faceplates are required to block
unused openings so that the normal bottom-to-top
airflow is maintained.
IC697ACC621 for 120VAC power source
IC697ACC624 for 240VAC power source
For detailed specifications and installation
instructions, refer to the documentation for the Rack
Fan Assembly.
IC697ACC644 for 24VDC power source
Note:
It is recommended that the fans be wired to the
same source of power as the PLC to ensure that the
fans are running when the PLC is active.
Typical Fan Assembly Mounted on Rack (AC Type Fan Assembly Shown)
A minimum of 23cm (9 inches) between
RX7i racks is required to remove and
replace an individual fan.
