KU4000
Series
minimum, and yet, due to the innovative housing design,
relatively large components can be mounted inside.
The terminals are machine solderable and have straight or right
angle pins, depending on enclosure type (Type C has straight
pins, Type B has right angle pins). We can also supply enclosures
with fewer than the maximum number of terminals, please
contact us with your requirements.
The KU4000 series are available in five
widths, and are supplied with
terminals in three standard positions:
• Terminals on top and bottom
• Terminals on one side only
• Terminals at both ends, the
center area has no terminals.
KU4011B
Versatile, compact enclosures are ideal for applications with
space constraints and for mounting within large international
style enclosures with 45mm (1.77 in.) cutouts, such as Altech's
EK and AK series nonmetallic enclosures. Small to medium in
size, KU4000 enclosures offer 8 to 64 terminals for field wire
connections. Pressure plate or spring cage terminals are
standard. The KU4000 series are equipped with double level
terminals which provide a maximum number of external
connections in a minimal amount of space. Standard enclosures
are supplied as kits, containing the base, cover and the
maximum number of terminals.

PROTECTION
KU4000 enclosures have an IP20 rating (finger protected) and
meet VBG4 and other European accident prevention
requirements.
CONSTRUCTION
The KU4000 series housings are supplied as
unassembled kits. Each kit consists of a flat
base, a housing cover and 8, 16, 24, 32, 48 or
64 terminals. Double level
terminals keep the
enclosure size to a
Cover plugs are available as
accessories and can be plugged into
unused screw holes and wire entries.
Plugs are offered as sets, consisting of
KU4012C
one screw-hole cover and one wire
entry cover
(Refer to Accessories in the Ordering Pages).
Integral printed circuit board guides are molded into the housing
cover to save time when inserting boards. They also prevent
misconnections and keep the boards from moving.
Printed circuit boards can be mounted in three ways:
•Horizontally, parallel with the base
•Vertically, perpendicular to the base
•Vertically, parallel with the DIN rail
One large board can be mounted against the base of the
enclosure (parallel with the base) using terminals with straight
solder pins. Boards can also be mounted vertically
(perpendicular to the base) by using terminals with right angle
solder pins, or vertically (parallel with the DIN rail) by using a wire
jumper connection.
(Refer to the Ordering Pages).
The face of the cover is 45mm
(1.77 in.) high, and can be
mounted into standard DIN
distribution systems which have
45mm cutouts like Altechs EK
and AK series of industrial
enclosures. Mount the KU4000
enclosures together with circuit
EK Series Industrial Enclosure
breakers and other DIN rail
mount devices which also meet the 45mm standard. Removal of
the housing cover is possible for service and repair after
disconnecting the wires. KU4000 covers cannot be potted
without taking special steps.

TERMINALS
Pressure plate terminals are

proof connection. The pressure

plate, which is captive to the

terminal screw, automatically rises
when the screw is loosened. One
or two wires of equal or different
PC Board in
2
(14 AWG) can
Horizontal
sizes up to 2.5mm
Position
be terminated in each terminal.
The grooved corners of the
pressure plate ensure positive retention of the wires. The flat bottom
of the terminal extends to the inside of the enclosure and provides
the terminal-to-board connection. The terminal screws can be
turned by a flat tip or a #2 Pozidriv screwdriver.
The KU4000 series is also available with spring cage terminals. The
terminal is opened by appling pressure with a screwdriver to open
the clamp. Once the wire is inserted, the screwdriver is removed,
creating a vibration proof connection to the wire.
TERMINAL-TO-BOARD CONNECTIONS
The KU4000 series offers several fixed terminal-to-board
connection possibilities. (Refer to the Ordering Pages for
connection types.)
Wire Jumper
connections can be made by soldering a wire
jumper between the center hole of the right angle solder pins and
the printed circuit board(s). Upon soldering, the board is installed
into the enclosure complete with terminals and other
components.
All KU4000 terminals have
Machine Solderable Pins,
which
can be machine soldered to the board(s) in the same step as the
other components, saving assembly time.
MOUNTING
The KU4000 enclosures snap onto standard 35mm DIN rail or
can be panel mounted. Mount one or several enclosures
together, or mix them with other DIN rail mounted devices such
as terminal blocks, circuit breakers, etc. The choice is yours.
MARKING
The KU4000 series have large marking areas on the front of the
cover.
ACCESSORIES
• Cover Plugs for Screw Hole and Wire Entries
• Screws for Mounting Printed Circuit Board
• Pull-Out Panel Mounting Tabs
• 35mm DIN Rail
CUSTOMIZATION
We can supply the KU4000,
series enclosure kits with the
exact number of terminals to
meet
your
requirements.
Enclosures can also be
customized with cutouts and
holes. Custom colors and
special markings are also
available.
Enclosure Mounting Procedures
DIN Rail Mounting
The top of the enclosure base has notches molded onto the
sides. The bottom of the base has one spring-loaded tab that is
factory installed into a molded guide for DIN rail mounting.
When mounting, tilt the bottom of the enclosure slightly away
from the rail until the notches grab onto the top flange of the DIN
rail. Push the bottom of the enclosure forward towards the DIN
rail. The spring-loaded tab will snap onto the bottom of the rail
and hold the enclosure firmly in place.
To remove the enclosure
from the DIN rail, insert a
screwdriver
into
the
exposed slot in the tab
and pull the tab down. Pull
enclosure forward and
remove from the rail.
Panel Mounting
To mount enclosures on a panel or any flat surface, at least one
tab must be in place on the top and on the bottom of the
enclosure base in the panel mount position. Standard enclosures
are supplied with one tab on the bottom for DIN rail mounting.
Install one or more additional tabs
(see Accessories in the
Ordering Pages)
into molded tab guides on the back of the
enclosure base. Move the pre-installed bottom tab from the DIN
rail position to the panel mount position.
To move the tab, insert a screwdriver under the spring pin, lift it
and pull the tab forward until it extends approximately 6mm(.25
in.) from the enclosure. Release pin and lock the tab in the panel
mount position.
We can supply the enclosures already set up for panel mounting
if desired.
(Please specify when ordering).
