Safety instructions
The operations must be carried
out by electrical suitably trained
in hazardous area with
knowledge of increased safty
explosion protection IEC 60079-14.
The distributions GHG 619 are not
suitable for Zone 0 and Zone 20
hazardous areas.
The temperature class and explosion
group marked on the distributions shall
be observed.
The requirements of the EN 61241-0 and -1
regarding excessive dust deposits and
temperature to be considered from the
user.
The permissible ambient temperature, the
terminal cross section and the self-
heating of the apparatus, that is mainly
caused by the power dissipation are to be
observed to ensure that the temperature
class stated on the type label of the
apparatus is maintained. (Test criterion for
the self-heating is an overload of 10%).
The user shall ensure that the overall
current of the bus-bar system does not
exceed 180 A.
The apparatus shall be used for the
intended purpose and shall be in a perfect
and clean state.
Only original parts from the manufacturer
may be used as replacements and for repairs.
Repairs that affect the explosion
protection may only be carried out by
Cooper Crouse-Hinds / CEAG or by a
qualified electrician in compliance with
the respective national regulations.
Modifications to the distributions or
design changes are not permitted.
Prior to being put into operation, the
distri-butions shall be checked in
accordance with the instructions given in
section 6.
Before initial operation, any foreign
matter shall be removed from the
distribution enclosures.
Before opening the enclosures, it is
necessary to ensure that the distributions
are isolated from the voltage supply or
take the appropriate protective measures.
The minimum terminal cross sections of
the flameproof components shall be
observed during connection in acc. with
EN 60 204-1:2007.
When using a bus-bar system, it is
necessary to ensure that the surge short-
circuit current of the mains supply does
not exceed the value I
S
= 47kA.
The minimum degree of protection IP 54
is no longer guaranteed when the MCB is
open.
The flap shall be closed again
immediately after actuating the
components, whereby the red lock
position indicator shall be fully visible
under the window.
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.
