Type CP7010 System Cabinet Assembly
This bulletin describes the following products:
Type CP7010 System Cabinet Assembly
Type CP7901 Cable Tray
Type CP7921 Cabinet Grounding Kit
Type CP7010 System Cabinet
Assembly
The Type CP7010 System Cabinet Assembly is an
equipment enclosure that houses rack-mounted
PROVOXr instrumentation such as controllers,
communications files, control I/O subsystem files, and
distributed I/O subsystem files. Cabinet dimensions
(Figure 1) allow single-depth mounting of all files. I/O
termination panels can be mounted front and back.
The cabinet can also house other instrumentation
requiring surface mounting. The cabinet may be joined
back-to-back or side-to-side to form cabinet groups.
Various wiring and cooling options may be selected to
meet instrument requirements.
A base assembly consists of the following:
Cabinet frame with lifting eyes and leveling feet
High temperature sensor
Full-length front door with keylock
Top and bottom panels
D001122X052
A plinth-type cabinet base raises the cabinet assembly
to allow bottom entry for power and signal wiring, if
raised flooring is not used. The base has removable
panels to allow use of a fork-lift or other lifting device,
for positioning of cabinets in the plant.
A high temperature sensor supplies heat monitoring
capability in each cabinet. The sensor is mounted at
the inside top of the cabinet. The sensor is used in
conjunction with the Type CP6103 System Power
Supply Unit, which provides the contacts to turn on an
external alarm. For additional information on the Type
CP6103 System Power Supply Unit refer to product
bulletin BU4.4:CP6103.
A rigid door frame provides integrity for the door and
an additional equipment mounting surface within the
cabinet. A continuous foamed-in gasket seals the
cabinet when the door is closed. Doors are available
with filtered lower cutouts used with top mounted fans
or with upper and lower filtered cutouts used with door
mounted fans.
Removable metal plates in the top panel provide
access for wiring. Top panels are available with
cutouts for two fans, or an air conditioner. Units with
solid top panels, and fans and filters in the door,
qualify for NEMA 12 applications. In cabinets with the
top mounted air conditioner, wiring access is from the
bottom. Bottom panels provide adjustable three-part
cable entry plates for entry access.
Side and back panels are available to fully enclose
cabinets. All panels use foamed-in gaskets to seal
panel and frame junctions. Side panels are available
with side mounted air conditioners. An optional rear
door is available for access to rear mounted I/O
termination panels.
The cabinets stand alone or bolt together in multi-bay
combinations. Side and back panels are not used
between joined cabinets. Shipping considerations limit
factory-assembled combinations to three bays or a
four pack.
Instrument Mounting
Cabinets assemblies are available with EIA rails for
rack-mounted instruments or an instrument mounting
panel for surface mounting. The panel installs on the
inside rear of the cabinet and can be adjusted in 1 inch
(25 mm) increments front and rear.

cabinet devices. Each cabinet with EIA rails includes a
horizontal tray that is mounted at the top. All other
horizontal trays are included with the rack-mounted
instruments.
Wiring
On units without a top-mounted air conditioner, power
and signal wiring enters the cabinet through a cutout in
the top panel or a three-part plate in the bottom panel.
On cabinet assemblies with a top-mounted air
conditioner, all wiring enters the cabinet through the
bottom panel.
Ventilation
The combination of doors with filtered cutouts and top
or door mounted fans provide required cooling. Where
conditions dictate sealed cabinets, air conditioning is
available with top or side mounted units to provide
environmental isolation and temperature control. Only
one air conditioner is required for every two joined
cabinets.
Laminated power bus bars are available to distribute
PRI 24 Vdc and SEC 24 Vdc power and ground to
rack mounted instruments. Bus bars mount vertically
inside the cabinet and have screw terminals spaced
throughout their length. Vertical cable trays are
available for routing power and signal wiring between

Type CP7921 Cabinet Grounding Kit
The Type CP7921 Cabinet Grounding Kit provides a
cabinet mounted, central termination point for all power
supply circuits located in system cabinets. This local
ground bus (LGB) is then connected to a single master
ground bus (MGB) and then to a single dedicated earth
ground for the instrumentation system. LGB assemblies
and MGB assemblies are available separately.
Each LGB assembly provides a central termination point
for all power supply and signal common circuits within a
cabinet group of eight bays or less. An assembly contains
eight screw terminals each for power supply and signal
common connections. It also includes two center tongue
terminal lugs; one for battery backup return line and one for
a MGB assembly connection.
Each MGB assembly provides a common termination point
for up to six LGB assemblies. An MGB assembly contains
seven center tongue terminal lugs. One lug is used for the
earth ground connection and the other six are used for
connection to LGB assemblies.

Weight: Wiring assembly for 1 to 3
cabinets (in-line) 2.8 pounds (1.28 kg)..
For 2 to 8 cabinets (back-to-back) 7.3
pounds (3.32 kg). For 4 to 8 cabinets
(in-line) 7.9 pounds (3.58 kg).
With one MGB connected to six LGB assemblies, each of
which is connected to eight cabinets, the power supply
circuits of up to 48 cabinets can be connected directly to
earth ground. If more than 48 cabinets are used, additional
grounding kits must be specified. When no more than eight
cabinets are used, the LGB assembly lug that is normally
connected to an MGB assembly is connected directly to a
single dedicated system earth ground.
