3 Safety Instructions
The most important safety instructions are summarized in this section. They supplement
the corresponding regulations which the staff responsible must study.
When working in areas, subject to explosion hazards, the safety of personnel and plant
depends on complying with all relevant safety regulations. Assembly and maintenance
staff working on installations therefore have a particular responsibility. They require 
precise knowledge of the applicable standards and regulations.
Use the breakers in accordance with their designated use and for their intended
purpose only (see “Function of Circuit-Breaker on page 3). Incorrect or impermissible
use or non-compliance with these instructions invalidates our warranty provision. No
modifications or alterations to the devices impairing their explosion protection are
permitted. The breakers must only be fitted and operated if they are undamaged, dry
and clean.
4 Function of Circuit-Breaker

The Series HLX-SWG-EB Circuit-Breaker protects cables against overload and
short-circuit in hazardous areas. It is designed for fitting into an enclosure with type
of protection increased safety.
As a user, please observe:
national and local safety and accident prevention regulations,
national and local assembly and installation regulations (e.g. IEC/EN 60079-14),
generally recognised technical regulations,
safety instructions and information in these operating instructions,
characteristic values and rated operating conditions on the rating and data plates,
instruction plates on the unit,
that any damage can invalidate the Ex-protection.

Fuses must be fitted upstream to protect circuit-breakers against high short-circuit currents in
high power networks. These protect thecircuit-breakers against short-circuit currents of up to 50
kA. If a short-circuit occurs, both protective devices cut out simultaneously, so that the circuit-
breaker is not destroyed and remains fully functional.

7 Installation
7.1 Mains Connection
7.2 Rated connection cross-section
Solid, stranded or finely stranded copper wires can be used. 1 or 2 wires of the same
cross-section can be fitted under one terminal. Both wires must be made of the same 
material. No preparation is necessary prior to connecting the wires.
Notice: Auxiliary contacts can be led out through the main contact terminals.
observe the cross-sections
note the terminal marking
Connect the cables with particular care.
Choose suitable cables and route them accordingly to ensure that the maximum 
permissible conductor temperatures are not exceeded.
To ensure that creepage distances are maintained remove precisely 10, 17 or 21 mm of
insulation (see chapter “Rated connection cross-section“).
The conductor must not be damaged (scored) when stripping the insulation!
Only heat-resistant cables must be used, if connected directly.
When terminal sleeves are fitted, they must be applied with a suitable tool.

7.3 Connection diagrams
Connect the device according to the rating plate. It has to be taken care that the neutral
conductor is connected correctly.
8 Commissioning
Before commissioning, ensure that:
the device has been installed in accordance with the standards,
the connections have been correctly made,
the device is not damaged,
all screws and nuts are fully tightened.
Note
As part of the installation procedure, the tight fit of the clamping connection must be che-
cked according to IEC/EN 60079-14, -17.
If necessary, the clamping connections must be retightened to the relevant torques.

9 Servicing
Maintenance
The following items must be checked as part of the maintenance schedule:
Check that no cable connections are loose.
Check the plastic enclosure for cracks or other visible signs of damage.
Check that the permitted temperatures, in accordance with IEC/EN 60079-0, are 
adhered to.
Check the reset function of the switch lever.
Check that the device functions correctly.
Maintenance Intervals
Check explosion-protected components regularly to ensure that its fitting, installation and
operation are in accordance with the regulations.
Refer to the corresponding national regulations (e.g. IEC/EN 60079-14) for the type and
scope of tests. The maintenance intervals must be chosen, such that the occurrence of
deficiences, anticipated in the system, can be avoided.
Note the following when establishing the intervals between checks:
the operating conditions (degree of utilization of the Miniatur Circuit-Breaker, 
maloperation)
manufacturers’ instructions in technical documentation (mechanical and electrical
service life)
major changes in the whole system (e.g. changes of zone allocation)
Remedial Action
Take the device out of operation! (Disconnect it from the supply!)
Replace with new device!
10 Transport and Storage
Transport and Storage are only permitted in the original packing.
11 Disposal
Maintenance and repair work on the devicess may only be carried out by appropriately
authorized and trained personnel.
Before any work commences, the devices must be disconnected from the supply.
Observe the relevant national regulations in the country of use!
Any defects, which affect the explosion protection, must be remedied immediately:
Observe the national standards for refuse disposal.
