6 Mounting
See fig.1
Before mounting the modules, it is necessary to check them to ensure
that they are in perfect condition. Special attention shall be given to any
possible transport damages (cracks and damage to the flameproof
encapsulation or any other damage to the modules).
When mounting the enclosures directly onto a mounting plate, they shall
rest evenly only on the fastening points provided for them and shall be
fixed without distortion (fig. 1
The screws used shall match the fixing hole (see dimensions drawing) and
shall not damage the hole (e.g. use of a washer, test torque 2,5 Nm).
If the fixing screws are overtightened, the apparatus may be damaged.
6.1

Electrical connection

See fig. 2
The electrical connection of the apparatus may only be carried out by
trained staff (IEC 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 must not
be damaged.
The minimum and maximum connectable conductor cross sections are to
be observed (see technical data, max. 185 mm²).
The built-in standard terminal is designed for the direct connection of
conductors with copper wires.
All screws and/or nuts of the connection terminals, including those not in
use, shall be tightened down securely.
The circuit diagram of the built-in components is shown on the modules,
included with the switch unit or included in the operating instructions.
When using multi- or fine-wire connection cables, the wire ends shall be
treated in accordance with the valid national and international regulations
(e.g. use of cable end sleeves).
6.2

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
of the modules shall be checked in accordance with these operating
instructions and other applicable regulations.
The incorrect installation can result in the invalidation of the guarantee.
