Empty enclosures GHG 716; industrial
GB
Applications other than those described are not permitted
without Cooper Crouse-Hind’s / CEAG prior written consent.
The instructions stated in section 7 of the operating instructions
shall be observed during operation.
The user alone is responsible for the appropriate use of this
junction box in consideration of the basic conditions existing at the
plant (see technical data).
6 Installation
For the mounting and operation, the respective national regulations as
well as the general rules of engineering will have to be observed.
6.1 Mounting
The units can be mounted without opening their enclosure.
If cable entries are used from the top, mount only in dry rooms or attach
where protected from moisture.
In case the terminal boxes are mounted directly onto the wall, they may
rest evenly only at the respective fastening points.
The chosen screw shall match the fastening hole (see dimensional
drawing) and it must not damage the hole (e. g. use of a washer).
If the screws are overtightened, the apparatus can be damaged.
6.1.1 Assembly of GHG 76.1 to GHG 76.3
Fix the fixing lugs to the bottom of the enclosure; facing either upwards
and downwards, or to the left and right (Fig 1).
Fix the enclosure with the fixing lugs to the wall.
6.1.2 Assembly of GHG 76.3 to GHG 76.8
Screw the enclosure onto the moulded-on fixing lugs.
Alternatively, the enclosures can be mounted using fixing lugs
that are available separately.
6.2
Opening of enclosures
6.2.1 Opening of enclosures without cover hinges
Unscrew cover fixing screws with a suitable screwdriver.
Enclosure cover is not safeguarded against falling down.
6.2.2 Opening of enclosures with cover hinges
Fig. 2
Unscrew cover fixing screws with a suitable screwdriver.
Lift the enclosure cover until the retension springs of the two side bolts of
the hinges engage.
Swing the cover sideways, max. 80°

Field of application
The empty enclosures are suitable for in-/outside use in industrial area.
The enclosure materials used, including any external metal parts, are high
quality materials which ensure a corrosion protection and resistance to
chemical substances corresponding to the requirements in a “normal
industrial atmosphere”:
-
Aluminum
In case of use in an extremely aggressive atmosphere, you can obtain
information concerning the chemical resistance of the materials used
from your Cooper Crouse-Hinds branch.

Application / Properties
The empty enclosures are intended for the distribution of electrical
energy e.g. light circuits, heater circuits, control circuits, intrinsically safe
circuits etc. in hazardous areas (see technical data).
The empty enclosures of sizes 6 to 8 sizes can be optionally equipped
with a hinge for the upper housing part.
The permissible operating temperature, see technical data.
The data as per point 3 and 4 shall be taken into account with the
use.
