Safety instructions

The control units GHG 418 .. are
not suited for use in Zone 0.
The operations must be carried
out by electrical suitably trained in hazardous
area with knowledge of increased safty
explosion protection IEC/EN 60079-14.
The temperature class and type of protection
stated on the apparatus shall be observed.
Modifications or changes to the control units
are not permitted.
They shall be used for their intended purpose
and shall be in a perfect and clean state.
Prior to being put into operation, the control
units shall be checked in accordance with the
instructions as per section 6.
Before initial operation, any foreign matter
shall be removed from the apparatus.
Apparatus without a protective cap may only
be built into approved or certified enclosures,
operating panels or switch cabinets.
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!

Field of application

The control units are intended for use in
potentially explosive atmospheres in zones 1,2 in
accordance with IEC/EN 60079-10-1.
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":
- impact resistant polyamide
When used in extremely aggressive atmos-
pheres, the additional data relating to the
chemical resistance of the plastics being used
shall be taken from the data sheet
GHG 902 4001 P0001.

5 Application / Properties
The control units GHG 418 .. are intended for the
local control of electrical installations in
potentially explosive atmospheres. These
apparatus components are built into switch
cabinets, operating panels or machinery
according to the individual requirements.
The version with gold-tipped contacts is suited
for switching extra-low voltage circuits. Special
attention shall be paid to the maximum current
load (see technical data, page 6). The contact
chamber of the gold-tipped version is marked
with the letter "G" or colour-coded.
To ensure a safe and reliable disconnection, the
normally closed contacts are designed as
compulsory opening contacts.
