1 General Information
These additional operating instructions are applicable only in conjunction with the Instal-
lation and Operating Instructions. They contain supplementary information on the spe-
cific requirements for use of the appliances in line with LCIE 03 ATEX 6202 X in areas
where there is a risk of explosion, in accordance with European Council Directive 94/9/EC
of 23 March 1994.
1.1 Uses
These submersible pumps are suitable for use in gaseous atmospheres requiring a group II,
category 2G appliance (use in zones 1 and 2), gas group IIB and temperature category T4.

Product data

1.2.1 Construction model
The explosion protection model provided falls into the fire protection category "flameproof
enclosure".
The following norms are upheld in particular:
Electrical materials for areas where there is a risk of explosion:
EN50014, General provisions
EN50018, flameproof enclosure "d"
Identification symbol: Ex II 2 G EEx d IIBT4

1.2.2 Operation parameters

The electrical parameters for the operation of the submersible pumps must be taken from
the rating plate. They are electrical values to be observed for new hydraulics when pumping
clear water and which can be operated to S1 as a maximum. The thermal protective switch
(WSK) will switch the pump unit off should these values be exceeded. To prevent misuse of
this function as a switch, ensure the submersible pump is operated below the switch-off
point at all times. We recommend that the operating current should be a maximum of 90%
of the nominal current (for nominal voltage decrease by the corresponding amount for high
voltage and under voltage). We also advise the operator to ensure when commissioning the
pump and at regular intervals thereafter that the pump is not overloaded.
A second, self-adhesive rating plate is enclosed in the documentation. We recommend af-
fixing this to the switching box, inside the Installation and Operation Instructions or in any
other suitable area to ensure you have the necessary operating data to hand at all times.

Safety

These instructions contain additional information which must be observed when installing
and operating the pump. These operating instructions must therefore be read by the in-
staller and the responsible operator before assembly and commissioning. In addition to the
general safety instructions laid down here in the Safety section, the special safety instruc-
tions laid down in the following sections are also to be observed. The general indications
provided in the Operating Instructions must also be observed.
