This section provides an overview of all key safety aspects for optimal protection of the staff as
well as for safe and fault-free operation.
Non-observance of these operating and safety instructions may result in considerable hazards.
3.1
General
The EK205-M is an intrinsically safe device and is suitable for operation within the zone at risk of
gas explosion 2 for gases of temperature class T4.
Check for use in zone 2 in accordance with the currently applicable rules of the art: see section
13.3:
DANGER!
Risk of explosion by connection to non-intrinsically safe and associated
equipment.
When operating the EK205-M in an area at risk of explosion (zones 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-M 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-M only to intrinsically safe pieces of equipment whose
electric data correspond to the requirements stated in the design test certificates
of the EK205-M (see section 13.3).
DANGER!
Risk of explosion from use of wrong batteries.
Use only batteries stated in the design test certificates of the EK205-M (see section
13.3). Order number see section 13.1.4.
DANGER!
Risk of explosion from incorrect use or connection!
During connection and operation of the EK205-M in areas at risk of gas explosion,
observe the associated norms:
DIN EN 60079-0
The device may only be used in an area at risk of gas explosion if the installation is
carried out in accordance with the general requirements of DIN EN 60079-0 and the
operating conditions (see section Technical data) and connection conditions (see
section Installation, connection, and commissioning) are observed.
The device can be hazardous if it is used by staff not trained correctly in an improper or
unintended manner.
