Enclosure and Cover Installation Instructions
WARNING: Enclosures that are powder coated have a potential electrostatic charging hazard. Wipe the enclosure down with a moist
cloth before servicing.
For additional nonmetallic enclosure instructions, please refer to the HKH polymeric enclosure installation instruction
Form - K1443.
a:
Using a screwdriver with a #2 Phillips Head, a Standard Slotted or Robertson style head, remove the cover screws. Securely fasten the
enclosure to the mounting location, using up to a
1/4” (M6)
diameter steel bolt and washer. The mounting location must be flat and provide
proper clearance, rigidity and strength to support the enclosure and all contained devices. Mounting dimensions are shown in this document.
b:
Install Internal Components per the Mfrs. installation instructions. (See
"Wiring and Terminal Block"
and
"Cable Gland / Conduit Entry"
Installation Instructions
Sections below).
c:
Grounding connections are available at the din rail, earth continuity plate and internal- external ground stud.
d:
Bonding connections are available on covers and boxes of all enclosures. All exposed metal should be bonded per local electrical codes.
e:
Closing / Installing the enclosure cover: Thread each cover screw half way into the threaded insert without completely tightening in a diagonal
pattern. Then complete installation of cover by tightening screws in the same diagonal pattern to a minimum torque of 3 Nm (26 lb-ins.) to a
maximum of 4 Nm (35 lb-ins.).
DO NOT OVERTIGHTEN OR USE AN IMPACT TOOL. A consistent fit over the entire length of the cover joint should be verified at the time of
installation.
f:
This enclosure is provided without cable glands / conduit sealing devices. Proper selection of cable glands / conduit sealing devices must
occur in the field.
g:
Cable fittings must be certified “Ex e” components per EN 60079-7. For lines which are not permanently installed, only cable fittings
appropriate for this purpose can be used. They are to be protected from loosening and locked against rotation, i.e. clips, cemented, etc., per EN
60079-7. The operating (service) temperature of the enclosure is limited to the temperature of the gland fitting if less than the enclosure
.
h:
Killark KDE series drain and breather may be installed. The operating temperature of the enclosure is limited to the temperature of the drain
and breathers if lower than the enclosure's.
Other drain and breathers may be installed, the user is responsible for ensuring that the
protection concept, temperature class and relevant IP rating is maintained.
i:
All unused conduit openings must be fitted with a certified close-up plug of equivalent minimum required IP rating as required.
Maintenance Instructions:
WARNING:
Before
servicing the enclosure, be sure ALL electrical power is
OFF and LOCKED OUT
.
WARNING: Enclosures that are powder coated have a potential electrostatic charging hazard. Wipe the enclosure down with a moist
cloth before servicing.
WARNING: Maintenance on the end product should be carried out by authorized and trained personnel only. Following any
maintenance, the enclosure gasket must be checked for damage before the cover is replaced / reinstalled.
a:
After initial installation, the unit should be inspected at regular intervals to verify the cover is tight; that all conduit or gland connections are
intact and free of corrosion and that the enclosure mounting bolts are tight and in good condition.
b:
Inspect flanged surfaces of the box and of the cover gasket. Surfaces must be free of nicks, dirt or any foreign particle build-up that would
prevent a proper seal. Check hinges to ensure they are improper working order.
c:
Should the surfaces be damaged, consult factory. Never attempt to rework the surfaces in the field. Surfaces must seat fully against each other
to provide the proper joint.
d:
Apply a light coating of Killark “LUBG” lubricant to the box flange before closing the cover. All cover screws must be installed tightly (25 to 36
lb-ins.) to ensure the joint between the box and cover is sealed prior to powering the unit. An improper joint can result in an explosion with the
possibility of physical injury and property damage.
e:
SJICH hinged covers are permanent and are not field removable or replaceable. Prior to securing the cover add lubrication to the hinge pin to
aid in operation and the free movement of the cover
Important
: Care is to be taken opening the cover to help prevent accidental damage to the
cover and cover gasket. Never apply excess force to the cover when closing the hinged cover. Never hammer the cover, this will deform the
covers and possibly reduce the protection level of the enclosure.
