Applications other than those described
are not permissible without a written
declaration of consent from Messrs.
COOPER CROUSE-HINDS / CEAG.
During 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 maintenance and
repair supply socket distributions in
consideration of the basic conditions
existing at the plant (see Technical data).

Installation
The respective national regulations as well as
the general rules of engineering shall be
observed for the mounting and operation.
The improper installation and operation of
maintenance and repair socket distribution
may result in the invalidation of the
guarantee.
6.1
Mounting
The maintenance and repair supply socket
distributions can be mounted without opening
the enclosures.
When the socket distributions are mounted
directly onto the wall, the distributions shall
rest evenly only at the fastening points
provided for them.
The chosen screw shall match the fastening
hole (see dimensional drawing).
The socket distributions shall be fixed with
four screws minimum.
6.2
Opening the device/
Electrical connection
The electrical connection of the apparatus
may only be carried out by specialized
personnel
Before opening the apparatus (safety
switch), ensure that it has been isolated
from the voltage supply, or take appropriate
protective measures.
Before opening, set the switch to the "ON"
position.
The properly bared conductors of cables shall
be connected with due regard to the
respective regulations.
Maintenance and repair supply socket distributions, GHG 981
The conductors shall be connected with
special care in order to maintain the
explosion category.
To maintain the explosion protection,
conductors shall be connected with special
care.
The insulation shall reach up to the
terminal. The conductor itself shall not be
damaged.
The minimum and maximum conductor
cross sections that can be connected shall
be observed (see Technical Data, page 9).
If desired, the safety switch 80A can be
connected using 35 mm² cable lugs (DIN 46
234 / 8-35).
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 >12mm).
All screws and/or nuts of connection
terminals, including those not in use, shall be
tightened down securely.
Excessive tightening may affect or damage
the connection.
The supply terminals are designed for the direct
connection of conductors with copper wires.
If multi- or fine-wire connection cables are
used, the wire ends shall be handled
according to the applicable national and
international regulations (e.g. use of multicore
cable ends).
The position of the connection terminals is
shown in the wiring diagrams on pages 8 and
9 of these operating instructions.
To ensure that the safety switch closes
correctly, switching at the switch shaft of the
switch insert is not permitted when the
apparatus is open.
In order to guarantee the functioning and
efficiency of the ELCB (RCD), the maximum
permissible earth resistances specified in the
installation requirements shall be observed.
If, to facilitate the feeding of conductors into
the enclosure, the switch insert is removed
from the enclosure base, it shall be put back
correctly before the electrical connection is
made.
6.3
Cable entries (KLE);
blanking plugs
Generally, only certified cable entries and
blanking plugs may be used.
Trumpet-shaped cable glands or other
suitable entries with additional pull-relief
shall be used for flexible cables.
When using cable entries with a lower IP
protection than that which applies to the
device (see pages 8+9, Technical Data), the IP
protection of the whole device is reduced.
The mounting directives applicable to the
cable entries used shall be observed.
Unused holes shall be sealed with a certified
blanking plug in order to establish the
minimum protection category.
In case of sealing inserts that are cut to size, it
is necessary to ensure that the insert is properly
adapted to the cable diameter.
When fitting the cable entries, taken that the
sealing inserts are case shall be appropriate
for the cable diameter.
In order to ensure the required minimum
protection category, the cable glands shall be
tightened down.
Overtightening might impair the protection
category.
Warning: When tightening the cap nut of
the metal cable entry (e.g. type ADL/ADE),a
suitable tool shall be used to safeguard the
gland against twisting.
All unused metric COOPER CROUSE-HINDS
/ CEAG cable entries shall be closed with the
certified blanking plug for metric cable
entries.
