Aluminum Junction Box

PN 897-850901-010 (Glass Lens version)
PN 897-850000-010 (Solid cover version)

This product is for use as a stand-alone certified junction box or for use in product applications where a
certified XP component junction box is part of a more advanced product package.

The Ratings are as follows:

Class 1, Division 1, Groups BCD
II 2 G Ex d IIB+H2
Ta -40ºC to 75ºC

Figure 1 Aluminum Condulet Approvals label

The ratings comply with EN 60079-0-2006 and EN 60079-1-2007 standards.

NOTE: Properly rated ¾” NPT blanking plugs must be installed on any conduit entry that is
not used. The blanking plugs shall be approved components and shall have hazardous location
ratings that are rated equal or greater than the junction box.

CSA

NOTE: All component types that may be attached to this ATEX and

box shall be approved components and shall have hazardous location ratings that are rated
equal to or greater than the junction box.

Special Conditions for Safe Use:

1. The equipment is only to be used in Zone 1 and Zone 2 hazardous locations.

2. Where necessary for safety, the contents of the enclosure shall comply with the appropriate
requirements of relevant standards for electrical apparatus for use in potentially explosive
atmospheres.

3. The assembled equipment shall comply with the appropriate requirements of relevant standards for
electrical apparatus for use in potentially explosive atmospheres.

4. The enclosed apparatus may be placed in any arrangement provided that an area of at least 20% of
each cross sectional area remains free to permit unimpeded gas flow and therefore unrestricted
development of an explosion.

5. Rotating or other devices creating turbulence shall not be incorporated.

6. Liquids shall not be used when there is risk of producing and explosive mixture by the decomposition
of or release of oxygen by these liquids.

7. Oil-filled contactors shall not be used.

8. The use of energy storage devices may present difficulties, due to the possibility of sparking, after
isolation from the supply, when the enclosure cover is removed. In addition, secondary cells, and in
some cases primary cells may emit flammable gas not considered under the normal certification
conditions. The following requirements shall apply:

8.1 All such devices shall be provided with adequate means to prevent incendive sparking when
flameproof covers are removed.

8.2 Enclosures which can be opened more quickly than the time necessary for the discharge of
incorporated capacitors to a residual energy of:

0.2 mJ for electrical apparatus of Group I or Group IIA, or

06 mJ for electrical apparatus of Group IIB

0.02 mJ for electrical apparatus of Group IIC

shall be provided with label stating delay needed before attempting to open the enclosure. If enclosed
components have a temperature above that of the temperature classification of the electrical apparatus a
label shall be provided stating the delay necessary before attempting to open the enclosure to allow the
component to cool below the temperature classification

9. No holes whether for mechanical or electrical purposes and whether blind or clear shall be drilled in
the enclosure other than those shown on the Component Certificate drawings.

10. All entry devices shall be of a type specified in the certification documents having an appropriate
component certificate and suitable for the conditions of use, or be specifically certified with the
apparatus.

11. Any unused entry shall be closed by a device of a type specified in the certification documents having
an appropriate component certificate and suitable for the conditions of use, or be specifically certified
with the apparatus.

12. The holder of the final Certificate will be required to provide information to enable the test authority
to verify compliance with the above and the relevant parts of the certification standard not explicitly
covered by the Component Certificate. (e.g., Temperature classification)

13. The window temperature must not exceed 75ºC.

Installation

Use the 0.25” mounting holes on the ears and suitable hardware for mounting to a wall or pipe.

Use internal and external grounding points as required or recommended by electrical installation
guidelines.

When installed with conduit runs, install a properly rated conduit seal within 18” of each conduit entry
point.

Properly rated ¾” NPT blanking plugs must be installed on any conduit entry that is not used.

Make sure the ambient temperature at place of installation is within the rated temperature limits of this
device.

Operation

Always remove power to devices within junction box prior to removing cover

Detcon J-Box Instruction Manual Rev. 0.0 Page 2 of 3

Aluminum Junction Box

A 7/64” (2.77 mm) Allen screwdriver tool is required for lock/unlocking of threaded cover prior to
removal.

If the cover cannot be unthreaded by hand force, use a wide span wrench (grabbing knobs on cover) or use
a strap wrench (grabbing circumference of cover) to unthread cover.

When returning junction box to service, always tighten the cover down snugly until the O-ring seal is
compressed.

Maintenance

If threading of cover becomes difficult, apply small amount of non-volatile non-corrosive thread grease to
keep aluminium threads from locking up.

Replace this junction box if there are visible signs of significant corrosion on the metallic enclosure. Replace
the cover if there is any evidence of damage to glass lens. Replace the O-ring if it is damaged.

Avoid scratching of the exterior paint to maximize corrosion resistance. Do not submerge in liquids.
Minimize direct exposure to highly corrosive vapors and liquids.
