DANGER!
Risk of explosion by connection to non-intrinsically-safe and associated
equipment.
When operating the EK205 in an area at risk of explosion (zones 0, 1 or 2) and
connecting devices without certification as an "associated piece of equipment",
there is a risk of explosion.
Therefore:
–
When used in an area at risk of explosion, connect the EK205 to certified,
associated pieces of equipment only in accordance with the valid rules of the
art stated in the design test certificates.
– Connect the EK205 only to intrinsically safe pieces of equipment whose
electric data correspond to the requirements stated in the design test
certificates of the EK205 (see chapter 9.3).
WARNING!
Risk from faulty connection of the device!
The connection of the device may be carried out by a gas expert only (see
chapter Safety). Faults in this process may result in fatal situations or
considerable material damage.
Therefore:
–
Have the connection of the calibrated device be carried out by a gas expert
only.
– Also involve this person for subsequent relocations.
– Do not perform any connection changes or relocations of the device
independently.
 During connection and commissioning of the EK205, observe the requirements of the
associated norms DIN EN 60079-0 and DIN EN 60079-14.

Have the wiring of the connections carried out correctly by a gas expert or a calibration
officer.
 Do not switch active outputs against one another.
 Close unused cable screw connections in accordance with DIN EN 60079-14 using a
plug or a suitable screw lid.
To program the device and carry out additional applications, you can also connect in addition
to the components stated in this chapter the serial and optical interfaces of the EK205 (see
chapter Construction and function).
