Safe use
Before mounting
• Read and observe the safety notes in these operating instructions!
• Ensure that the contents of these operating instructions are fully understood by the personnel in charge.
• Use the device in accordance with its intended and approved purpose only.
• Always consult with R. STAHL Schaltgeräte GmbH if using the device under operating conditions which
are not covered by the technical data.
• Observe the document "Cabinet installation guide" for engineering (download from www.stahl-ex.com,
product documentation, subitem "Engineering").
• We cannot be held liable for damage at the device caused by incorrect or unauthorized use
or non-compliance with these operating instructions.
For mounting and installation
• Observe national installation regulations (e.g. IEC/EN 60079-14).
• Observe national safety and accident prevention regulations.
• During installation and operation, observe the information (characteristic values and rated operating
conditions) on the rating, data and information plates located on the device.
• Before installation, make sure that the device is not damaged.
• Electric circuits with type of protection "Ex i" operated with circuits with other types of protection can no
longer be operated as circuits with type of protection "Ex i" after that.
• When used in Zones 2 and 22, the intrinsically safe devices of Zones 1, 0, 21 and 20 can be connected
to the intrinsically safe signal circuits.
• The safety characteristic values of the connected field devices must correspond to the specifications in
the data sheet or in the EC Type Examination Certificate.
Maintenance, repair, commissioning
• Before commissioning, make sure that the device is not damaged.
• Work on the device, such as installation, maintenance, overhaul, repair, may only be carried out by
appropriately authorised and trained personnel.
• Perform only maintenance work or repair described in these operating instructions.
• Connect the device only to equipment which does not carry voltage higher than 253 V AC (50 Hz).
• Changing the DIP switch settings is also permitted during operation in Zone 2 and with connected
intrinsically safe input signals.
• Set up the power supply for 24 V DC so that it can so bridge interruptions of 20 ms (power failure
bridging in accordance with EN 61326-3-2 and NE 21).
• The devices must be installed in enclosures which comply with the requirements of the installation
location.
• 9185/11 only: Intrinsically safe Zone 1 devices can be connected to the intrinsically safe signal circuits.
• Intrinsically safe signal circuits must not be connected to the fieldbus isolating repeater 9185/12.
