Features
Provides additional rack cooling
Three fans per assembly
Easy installation
120 VAC, 240 VAC, or 24 VDC models
Used with 9-slot IC697 standard racks, 17-slot
IC697 VME Integrator racks, and IC698 racks
Functions
The Rack Fan Assembly is an easily installed
accessory for use with IC697 standard 9-slot racks,
VME Integrator 17-slot racks and IC698 racks. The
fan assembly consists of three fans. This fan
assembly provides additional rack cooling for
installations where heat buildup could be a problem.
The fans have a low noise level and use ball
bearings for extended life.
It is recommended that the fans be wired to the
same source of power as the PLC. This will ensure
that the fans are running when the PLC is active.
AC Rack Fan Assemblies (IC697ACC721/724):
The three fans are wired in parallel using a cable
assembly (supplied with the fan assembly) that
plugs into the three fan wiring connectors (see
Figure 1). When the cable assembly is installed, the
fan on the left (looking at front of rack) will have a 3foot lead with stripped ends for connecting to the
120 or 240VAC power source.
24 VDC Rack Fan Assembly (IC697ACC744): For
Revision B Rack Fan Assemblies and later, the
power cable wiring is the same as for the AC Rack
Fan Assembles (IC697ACC721/724). For earlier
versions, the three fans each have a pair of 12" (310
mm), 24 AWG leads. Connect these leads in
parallel, with all red leads connected to +24 VDC,
and all black leads connected to 24 VDC Common.
Use wire ties to fasten leads down.
Rack/Fan Assembly Compatibility
The following, and later, versions of the Rack Fan
Assemblies IC697ACC721B, 724B, and 744 are
compatible with the following racks:
IC697CHS782A and or later versions
IC697CHS783A or later versions
IC697CHS790D or later versions
IC697CHS791D or later versions
IC698CHS017 and IC697CHS117, all versions
Note: This version of the Rack Fan Assembly is
compatible with racks built to conform to shock
and high vibration specifications. These high
vibration racks have an SV suffix added to the
existing rack suffix. For example,
IC697CHS790ESV denotes that the rack is a
high vibration rack. All rack mounting
dimensions and instructions in this data sheet
apply to high vibration racks.
Earlier versions of the fan assemblies
IC697ACC721A and 724A are compatible with the
following IC697 racks.
IC697CHS782A, B only
IC697CHS783A, B only
IC697CHS790D only

Installing the Fan Assembly
Note:
To install the fan assembly, use the following
instructions (refer to Figure 3). The only tool you need
to attach the fan assembly to the rack is a #2 Phillips
screwdriver.
A minimum of 23cm (9 inches) between racks
is required to remove and replace an
individual fan.

Mounting Fan Assembly on Racks
1. Position the fan assembly on the bottom of the
rack and slide the flange on the rear of the fan
assembly (flange without slots) under the lip of
the rear rail on the rack.
2. While doing this, align the two holes in each end
of the fan assembly with the holes in the rack side
plates.
3. Install two screws in each end and secure the fan
assembly by tightening the screws to 10-12 in.lbs.
4. There are two additional screws that must be
installed in the front rail. Install these screws and
tighten to 10-12 in.-lbs.

Changing the Filter
Each fan has a polyurethane filter which can be
removed, and cleaned or replaced as needed.
Removing a filter is easy, simply lift the tabs located
on all four sides of the plastic retainer. Remove the
filter and either clean it or replace it with a new filter.
To replace a retainer, align the retainer with the filter
assembly and snap the retainer back in place. Details
of the filter assembly are shown in the following
figure.
