Explosion protected terminal boxes made of plastic or
stainless steel type GHG 72.
The data as per point 3 and 4 shall be
taken into account with the use.
Applications other than described are not
permitted without CEAG / CCH's prior
written consent.
For the operation, the instructions stated
in section 7 of the operating instructions
shall be observed.
The user alone is responsible for the
appropriate use of this installation switch
in consideration of the basic conditions
existing at the plant (see technical data).

Installation

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

6.1 6.1 Mounting Mounting
The plastic and stainless steel terminal boxes
can be mounted without opening their
enclosure.
When mounting the terminal boxes directly
onto the wall, they shall rest evenly only on
the fastening points provided for them. The
chosen screw must match the fastening hole
(see dimensional drawings page 9 - 11) and
they shall not damage the hole (e.g. use of a
washer).
The terminal boxes must be fastened
diagonally by means of at least 2 screws.
If the screws are overtightened, the
plastic terminal boxes may be damaged.
The plastic terminal boxes GHG 721 0 and
GHG 721 0 are suitable for fastening onto
CEAG / CCH apparatus holders by means of
self-cutting screws and clip-on mounting (see
fig. 4 - 7, page 14 + 15).
The respective mounting instructions will
have to be observed.

6.2 Opening the apparatus/

Electrical connection

The electrical connection of the apparatus
may only be carried out by skilled staff.
The table indicating the current load values
which is provided on the cover inside of the
terminal boxes is to be observed.
In order to maintain the mode of protection,
the conductors will have to be connected with
special care.
The insulation shall reach up to the
terminal. The conductor itself shall not be
damaged.
The connectible min. and max. conductor
cross-sections will have to be observed.
All screws and/or nuts of the supply
terminals, and unused terminals, shall be
tightened down.
The fitted standard terminals are designed
for direct connection of conductors with
copper cores.
If stud terminals are fitted, DIN cable lugs
shall be used.
Attention: The cable lugs should be
crimped onto the cable in a workmanlike
manner. It is to be ensured that the
required min. air gaps are kept
(at 690V ò12mm).
In case of mixed equipment Ex e / Ex-i, the
required minimum distances will have to be
kept (see e.g. EN 60079-11).
After removing the terminal rail (in order to
facilitate the entry of cables), the terminal rail
shall again be propperly put in place before
establishing the electrical connection.
Removal and mounting of the terminal rail are
performed as follows:
By pressing apart the enclosure sides, the
terminal rail can be detached from the bottom
part of the enclosure. In order to install the
terminal rail, it is fitted onto the catch on one
side of the enclosure wall and then snapped
in on the opposide enclosure wall (see fig. 3).
The PE rail can optionally be fitted in 4
positions (see fig.1):
A Enclosure top side - PE-connection bottom
B Enclosure top side - PE-connection top
C Enclosure bottom side- PE-connection bottom
D Enclosure bottom side- PE-connection top
The PE rail is fitted as follows:
It has to be pushed home in the respective
guide rails that are integrated into the lateral
enclosure walls.
Attention: Care has to be taken that the
PE rail has such a position that a proper
conductor connection is ensured.
In the case of building up the electrical
equipment in the "protective insulation"
version, appropriate sticker
( ) GHG 905 1002 P0005 can be
requested by the manufacturer.
If the inserted terminal rail is not equipped
completely with line-up terminals, the terminal
rail must be included in the equipotential
earth connection also.
