7. Push the protective cap over the connection terminals until the clips,
item 14, engage in the grooves of the component, item 1 (see Fig. 3).
Special attention shall be piad to the correct fit of the seal, item 6.
8. Tighten the connection cable in the protective cap with the pressure
screw, item 8 (see Section 6.3).
To dismantle, proceed in the reverse order. To release the protective cap,
the clips are pushed out of the grooves in the component, item 1, using
the dismantling tool (item 13) and the protective cap removed (see Fig. 4).
6.2

Opening apparatus / Electrical connection

Before opening the apparatus (pulling off protective cap), it is
necessary to ensure that there is no voltage or to take suitable
protective measures.
The electrical connection of the may only be carried out by special-
ists (IEC/EN 60079-14).
The properly bared conductors of cables shall be connected with due
regard to the respective regulations.
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).
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 compo-
nents or in the operating instructions.
6.3

Cable entries (KLE); blanking plugs

When fitting cables, care shall be taken to use sealing inserts of the cable
entry of the protective cap that are suited for the respective cable
diameter.
In order to ensure the required minimum degree of protection, the
pressure screws shall be tightened down securely.
Overtightening can impair the degree of protection.
6.4

Closing apparatus

Any foreign matter shall be removed from the apparatus.
In order to ensure the required minimum degree of protection, the
protective cap and the actuating element shall be mounted correctly in
accordance with the instructions (see 6.1).
Overtightening can impair the degree of protection.
6.5

Putting into operation

Before putting the apparatus into operation, the tests specified in the
individual national regulations shall be performed.
In addition to this, before being put into operation, the correct functioning
and installation of the apparatus and built-in components (signal lamps,
pushbuttons, etc.) shall be checked in accordance with these operating
instructions and other applicable regulations.
The improper operation of control units may result in the invalida-
tion of the guarantee.

The valid national regulations for the servicing / maintenance of
electrical apparatus for use in potentially explosive atmospheres
shall be observed (IEC/EN 60 079-17).
Prior to opening the enclosure, it is necessary to ensure that the
voltage supply has been isolated or to take suitable protective
measures.
The necessary intervals between servicing depend upon the specific
application and shall be stipulated by the operator according to the
respective operating conditions.
During servicing, above all, the parts on which the explosion protection
depend, (e.g. intactness of the flameproof components, the enclosure,
the seals and cable entries), and the switch mechanism function of the
control switch shall be checked.
If, in the course of servicing, it is ascertained, that repairs are necessary,
section 8 of these operating instructions shall be observed.
8
Only original COOPER CROUSE-HINDS / EATONparts shall be used for
carrying out repairs.
In the event of damage to the flameproof encapsulation, replacement
of these components is mandatory. In case of doubt, the respective
apparatus shall be sent to COOPER CROUSE-HINDS / EATONfor
repair.
Repairs that affect the explosion protection may only be carried out
by COOPER CROUSE-HINDS / EATONor by a qualified electrician in
compliance with the respective national regulations
(IEC/EN 60 079-19).
Apparatus modifications or design changes are not permitted.
When replacing individual built-in components (pushbuttons, etc.) section
6.2 "Opening apparatus / Electrical connection" shall be observed.
9
The respective valid national regulations for waste disposal shall be
observed when disposing of apparatus and built-in components (measur-
ing instruments, signal lamps, pushbuttons, etc.).
To facilitate the recycling of individual parts, parts made of moulded plastic
shall bear the marking for the type of plastic used.
The product range is subject to changes and additions.
