6.2 Opening apparatus/
Electrical connection
Before opening the distribution enclosure,
it is necessary to ensure that the distri-
butions are isolated from the voltage
supply or to take suitable protective
measures.
The electrical connection of the apparatus
may only be carried out by trained staff.
The properly bared conductors of cables shall
be connected with due regard to the
respective regulations.
To maintain the explosion protection, con-
ductors 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.
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.
All screws and/or nuts of the connection
terminals, including those not in use, shall be
tightened down securely.
The built-in standard terminal is designed for
the direct connection of conductors with
copper wires.
DIN cable lugs shall be used to connect the
built-in bus bars and bolt terminals.
Warning: The cable lugs shall be crimped
onto the cable in a workmanlike manner. It
is necessary to ensure that the minimum
required clearances are maintained
(<12mm for 690V).
If connection terminals up to 240mm² (bolt
terminals) are built into the terminal boxes,
these terminals shall be wired as shown in
Fig. 10, page 32 (max. 2x 240mm²).
In the case of mixed Ex-e / Ex-i
installations, the required minimum
clearances shall be maintained (see, for
example, EN 60079-11).
The instructions for the installation of
intrinsically safe electrical apparatus shall
be observed.
