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.
To maintain the explosion protection, con-
ductors 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).
If desired, the safety switch GHG 264 (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 maintained (at 690V ≥12mm).
In the case of mixed Ex-e / Ex-i installations,
the required minimum clearances shall be
maintained (see, for example,
IEC/EN 60079-11).
When apparatus is open, (isolate voltage
supply) , it is necessary to ensure that no
voltage is carried over into the connected
intrinsically safe circuits.

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 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).
Refer to the wiring diagrams on page 11 for the
position of the connection terminals. An
example of one possible circuit arrangement is
shown in Fig. 5, page 14.
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.
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.
