All screws and/or nuts of connection terminals,
including those not in use, shall be tightened
down securely.
The standard terminals are designed for the
direct connection of conductors with copper
wires.
The circuit diagram of the built-in components
is shown on the components or attached to
them, or it is shown in the operating instruc-
tions.
!
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.
If, to facilitate wiring, the built-in components
(AM/VM72 and AM/VM45 measuring instru-
ments, pushbutton contact block, signal lamp
bases, control switch contact blocks, potenti-
ometer bases, etc.) are snapped off the rail on
the bottom of the enclosure, the components
shall be snapped back properly into the same
notch on the rail.
To snap off components (including the
measuring instruments AM/VM72 and AM/
VM45), pull the hooks outwards to release
them.
To ensure that the apparatus closes correctly,
switching at the switch shaft of the switches
insert is not permitted when the apparatus is
open.
a Warning: the engaging positions of the
built-in components shall matches the
notches on the rail!
6.3

Cable entries (KLE);

blanking plugs

a
Generally, only certified cable entries and
blanking plugs may be used. Flexible cables
shall be used with trumpet-shaped cable
glands or other suitable entries with
additional pull relief.
The relevant mounting directives for cables
entries being used shall be observed.
When using cable entries with a degree of
protection that is lower than the IP protection of
the apparatus (see page 9), the degree of IP
protection for the complete unit is reduced.
Intrinsically safe circuits shall be fed through
cable entries that are colour-coded (light blue).
When using cable entries for fixed cables it is
necessary to ensure that no inadmissible high
mechanical stress is applied to the cable entry
or its seal.
In order to ensure the minimum degree of
protection, any unused entry holes shall be
sealed with certified blanking plugs.
When fitting cable entries, care has to be taken
that the sealing inserts are suitable for the cable
diameter. In the case of sealing inserts that are
cut out, it is necessary to ensure that the insert
is properly adapted to the cable diameter.
In order to ensure the required minimum
degree of protection, the cable entries shall be
tightened down securely.
a
Overtightening can impair the degree of
protection.
a
Warning: When tightening the cap nut of
the metal cable entry (e.g. type ADE;
CMDEL), a suitable tool shall be used to
safeguard the gland against twisting.
Any unused metric CEAG cable entries shall be
sealed with the blanking plug certified for these
metric cable entries.
6.4

Flange and metal plates *

If flange plates have to be dismantled, (e.g. to
drill entry holes), when replacing the plates, in
order to maintain the minimum degree of
protection, it is necessary to ensure that the
flange plate and the fixing clamp fit correctly.
a
PE conductors fed from outside shall be
connected to the PE terminal provided on
the flange. the maximum terminal cross
section is 6 mm².
a Warning: Metal flanges, metal plates and
metal glands shall be incorporated in the
potential equalization.

6.5

Closing apparatus /

Cover closure

a
When fitting the enclosure cover onto the
base, it is necessary to ensure that the
actuator elements correspond correctly with
the built-in components, care shall be taken
to ensure that the switch shaft of the switch
insert engages correctly in the carrier hole of
the switch handle and that the enclosure
cover for the respective base is being used.
The switch handle shall be in the position it had
when the apparatus was opened.
Any foreign matter shall be removed from the
apparatus.
To ensure the required minimum degree of
protection, the cover screws shall be tightened
down.
Overtightening may impair the degree of
protection.
