Field of application
Modules of the series GHG 62. may be built
into enclosures in the type of protection
”increased safety” (EN 60079-7). When built
into these Ex e enclosures, the modules are
suited for use in both Zone 1 and Zone 2
hazardous areas in accordance with EN/IEC
60079-14 and EN/IEC60079-10-1!
The enclosure materials used, including any
external metal parts, are high quality materials
that ensure a corrosion resistance and
resistance to chemical substances according
to the requirements for use in a ”normal
industrial atmosphere”

Application / Properties
The explosion-protected module enclosures
in accordance with EN 60079-1 are used for
the flameproof encapsulation of switchgear
such as circuit breakers that give off arcs or
sparks during normal operation and, as a
result, could ignite an existing potentially
explosive atmosphere.
The use of these modules depends on the
respective encapsulated switch unit.
Important: When using these modules,
the technical data and the connection
diagram on the type label shall be
observed.
When circuit breakers are flameproof
encapsulated in the enclosures, after several
short circuits it is necessary to test the
modules to ensure that they function
correctly.
A signal contact (optional) on a circuit breaker
is actuated by an overload, earth fault or
short circuit. It cannot, however, be tripped if
the circuit breaker is switched manually.
When special switch or control units are
flameproof-encapsulated in these module
enclosures, details relating to the properties
and use of these modules shall be taken from
the respective supplementary sheet.
When RCCBs and RCBOs are flameproof
encapsulated in the enclosures, after several
short circuits it is necessary to test the
modules to ensure that they function
correctly. An RCCB/RCBO does not prevent
the feeling caused by an electric shock, but
limits the duration of the current flow through
the human body to such an extent that the

Safety instructions
The modules GHG 62. are not
suitable for Zone 0 hazardous
areas.
Warning: These modules shall be built
into an enclosure that fulfils the
requirements of a recognized type of
protection acc. to EN 60079-0.
The letter ”U” in the certification number
means that this component certificate
may only be used as a basis for the
certification of apparatus or protective
systems.
The permissible ambient temperature
range and the self-heating of the
apparatus, that is mainly caused by the
power dissipation are to be observed to
ensure that the operating temperature
range stated on the type label of the
apparatus is maintained.
The temperature class of the complete
installation or distribution is determined
by the power dissipation of all the built-in
modules and components.
Observe the directives for self-heating.
The apparatus shall be used for the
intended purpose and shall be in a perfect
and clean state.
Modifications to the distributions or
design changes are not permitted.
Prior to being put into operation, the
modules shall be checked in accordance
with the instructions given in section 6.
The minimum terminal cross sections of
the flameproof modules shall be observed
during connection in acc. with
EN 60204-1:2008.
The national safety rules and regulations
for the prevention of accidents, as well as
the safety instructions included in these
operating instructions, that, like this text,
are set in italics, shall be observed.
