Safety instructions

The junction boxes are not suitable
a
for Zone 0 and Zone 20 hazardous
areas. The temperature class and
explosion group marked on the junction
boxes shall be observed.
The requirements of the IEC/EN 60079-14
regarding excessive dust deposits and
temperature to be considered from the user.
They shall be used for their intended
purpose and in perfect and clean condition.
Prior to taking the junction boxes into
operation, they shall be checked in accord-
ance with the instruction as per section 6.
Observe the national safety rules and
regulations for prevention of accidents as
well as the safety instructions included in
these operating instructions and set in
italics the same as this text!

Field of application

The junction boxes GHG 791 01 and GHG 791
02 are suitable for use in Zones 1 and 2 as well
as in Zones 21 and 22 hazardous areas acc. to
IEC/EN 60 079-10-1 and IEC/EN 60 079-10-2!
The enclosure materials employed, including
the exterior metal parts, are made of high-quali-
ty materials which ensure a corrosion protec-
tion and resistance to chemical substances
corresponding to the requirements in a "normal
industrial atmosphere":
– impact resistant polyamide
– special steel AISI 316 L
In case of use in an extremely aggressive
atmosphere, please refer to manufacturer.
5 Use/Properties
The junction boxes are intended for the
distribution of electrical energy (e.g. light
circuits, heater circuits, control circuits etc.) in
hazardous areas up to max. 39A (see technical
data). The temperature class, explosion group
and permissible ambient temperature, see
technical data.
If the conductor cross-section in the junction
box is reduced, the maximum ampacity of
the conductor with the smallest cross-sec-
tion and the rated current of the junction
box must be taken into account.
The junction boxes can also be used in a
„normal industrial area" .
The data as per point 3 and 4 shall be taken
into account with the use.
Applications other than described are not
permitted without Cooper Crouse-Hinds's
prior written consent.
For the operation, the instructions stated in
section 7 of the operating instructions shall
be observed.
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).
