Safety instructions

The junction boxes are not
suitable 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 EN 61241-0 and -1
regarding excessive dust deposits and
temperature to be considered from the
user.
Modifications to the junction boxes or
changes of their design are not permitted.
They shall be used for their intended
purpose and in perfect and clean
condition.
For replacement and repair only genuine
Cooper Crouse-Hinds spare parts shall be
used.
Repairs that affect the explosion
protection, may only be carried out by
Cooper Crouse-Hinds or a qualified
electrician in compliance with the
respective national regulations.
Prior to taking the junction boxes into
operation, they shall be checked in
accordance with the instruction as per
section 6.
Before the initial operation, any foreign
matter shall be removed from the junction
boxes.
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!

Conformity with standards

The apparat is conform to the standards
specified in the EC-Declaration of conformity.
It has been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001.

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 60 079-10!
The enclosure materials employed, including
the exterior metal parts, are made of high-
quality materials which ensure a corrosion
protection 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 aggresive
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.
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.

Installation

For the mounting and operation, the
respective national regulations as well as the
general rules of engineering shall be
observed.
6.1

Mounting

The junction boxes can be mounted without
opening their enclosure.
In case the junction 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).
