K70 Enclosure Series

Unspecified 

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

breakers and other DIN rail

mount devices which also meet

EK Series Industrial Enclosure

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.

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.

TERMINALS

Pressure plate terminals are standard for the KU4000 enclosure and

ensure a vibration 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 sizes up to 2.5mm2

(14 AWG) can 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 Philips 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.

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.

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 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.

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).
