1 Operation instruction for Explosion protected control panels
1.1 Application and Standards
This instruction manual applies to explosion protected control panels of type of protection types below. This
apparatus is only to be used as defined and meets requirements of EN 60 079 particularly EN60 079-14
"electrical apparatus for potentiality explosive atmospheres". It can be used in hazardous locations which are
hazardous due to gases and vapours according to the explosion group and temperature class as stipulated on
the type label. When installing and operating the explosion protected distribution and control panels the
respective nationally valid regulations and requirements are to be observed.
1.2 General Instructions
The control panel has to have a back-up fuse as stipulated. The mains connection must have a sufficient short
circuit current to ensure safe breaking of the fuse. To achieve an impeccable and safety device operation,
please take care for adept transportation, storage and mounting, as well as accurate service and maintenance.
Operation of this device should only be implemented by authorised persons and in strict accordance with
local safety standards. The electrical data on the type label and if applicable, the "special conditions" of the
test certificate PTB 98 ATEX 2071 are to be observed.
For outdoor installation it is recommended to protect the explosion protected distribution and control panel
against direct climatic influence, e.g. with a protective roof. The maximum ambient temperature is 40°C, if
not stipulated otherwise.
1.3 Before using the device
All connections and connection points must be checked for correct cabling. Operation with damaged cables
is not permitted.
1.4 Intrinsically Safe Circuits
Erection instructions in the testing certificates of intrinsically safe apparatus are to be observed. The electrical
safety values stipulated on the type label must not be exceeded in the intrinsically safe circuit. When inter-
connecting intrinsically safe circuits it is to be tested, whether a voltage and/or current addition occurs. The
intrinsic safety of interconnected circuits is to be ensured. (EN 60079-14, section 12)

Safety Measures: to read and to comply
Work on electrical installations and apparatus in operation is generally forbidden in hazardous locations, with
the exception of intrinsically safe circuits. In special cases work can be done on non-intrinsically safe circuits,
on the condition that during the duration of such work no explosive atmosphere exists. Only explosion pro-
tected certified measuring instruments may be used to ensure that the apparatus is voltage-free. Grounding
and short circuiting may only be carried out, if there is no explosion hazard at the grounding or short circuit
connection.

Safety aspects
A batch control system built exclusively with the DC155 represents a
control system in category 1 according EN954-1. If a higher safety is
required, it is necessary to install independent working safety
facilities.
