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 RX7i 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:
fifteen single-width modules (with no doublewidth modules installed),
eight 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, 17-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 AC power supplies
Supports higher wattage power supply for highcurrent configurations.
Supports an optional cooling fan assembly
(required for IC698CPE020 or IC698CRE020).

Rack Mounting
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.
These racks accommodate two module types:
Overall rack dimensions are 11.15"H x 19"W x 7.5"D
(283 x 483 x 190mm).
Note:
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.
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 rack must be mounted in the orientation shown
in the following figures. Sufficient space must be left
around the rack to allow air flow for module cooling.

Safety Ground
I/O point references for modules in an RX7i rack are
configured using the CIMPLICITY® Machine Edition
Logic Developer-PLC software. For information on
configuration, see the software online help and the
CIMPLICITY Machine Edition Logic Developer-PLC
Getting Started manual, GFK-1918.
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.
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.
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.

Warning
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.
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.
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.
A blank faceplate is available to cover two
consecutive unused slots in the rack or a single
unused slot (IC698ACC735 – single-width;
IC698ACC720 -double-width).
3. The GND terminal on the rack must be
connected to a reliable earth ground.
Insulating Strips for High Voltage Modules
Note: RX7i modules with faceplates fitted with an
EMI gasket (a metal strip along the side of the
faceplate) 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.) 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 into a metal
enclosure to achieve similar noise improvement.
Module Retention
Series 90-70 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 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.
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. Note that it is
mounted on the bottom of the rack with air flow from
the bottom towards the top of the rack. When using
the fan assembly, filler faceplates are required to
block unused openings so that the normal bottom-totop airflow is maintained.
IC697ACC721 for 120 VAC power source
IC697ACC724 for 240 VAC power source
For detailed specifications and installation
instructions, refer to the documentation for the Rack
Fan Assembly.
IC697ACC744 for 24 VDC 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.
