Safety instructions

6062
The terminal and bus bar boxes
GHG 75. are not suitable for Zone
0 and Zone 20 hazardous areas.
6065
Even when used together with flanged-
mounted flameproof enclosures, these
6033
boxes shall not be used in Zone 0 and
Zone 20.
The operations must be carried out by
6170
electrical suitably trained in hazardous
area with knowledge of increased safty
explosion protection
. 021
IEC 60079-14.
The requirements of the EN 61241-0 and -1
. 023
regarding excessive dust deposits and
temperature to be considered from the
user.
. 024
The temperature class and explosion
group marked on the terminal boxes shall
be observed.
. 061
To ensure adherence to the temperature
class stated on the type label of the
apparatus, the permissible ambient
. 063
temperature, the rated terminal cross
section and the self heating of the
apparatus mainly due to the power
. 066
dissipation shall be taken into account
(test criterion for the self heating is an
overload of 10%).
. 067
The operator is required to ensure that
the overall current for the bus bar
systems does not exceed 275 A
(2x20x5mm), 440 A (3x20x5mm), 693 A
(2x30x10mm).
Modifications to the terminal boxes or
6
design changes are not permitted.
They shall be used for their intended
Special switch
purpose, whereby they shall be in a
mechanism
perfect and clean state.

replacements and for repairs.
Repairs that affect the explosion
protection may only be carried out by
CEAG or by a qualified electrician in
compliance with the respective national
regulations.
Prior to being put into operation, the
boxes shall be checked in accordance
with the instructions given in section 6.
Before opening the enclosure, it is
necessary to ensure that the terminal box
is isolated from the voltage supply or take
the appropriate protective measures.
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.

The terminal and bus bar boxes GHG 75. are
conform to the standards specified in the EC-
Declaration of conformity, enclosed
separately.
It has been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001
94/9 EC: Equipment and protective systems
intended for use in potentially explosive
atmospheres.
The terminal boxes fulfil further requirements,
such as the EC directive on electromagnetic
compatibility (2004/108//EC).
They have been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001.
