For assembly and installation
• Observe national assembly and 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 type plates and data plates and information signs
located on the device.
• Install the device in Zones 2, 22 or outside of hazardous areas.
• When used in Zones 2 or 22, the device must be built into an enclosure which
corresponds to the requirements of IEC/EN 60079-15 or IEC/EN 60079-31.
• Electric circuits with the "Ex i" type of protection operated with circuits with other types
of protection can no longer be operated as circuits with the "Ex i" type of protection
after this stage.
• Connect the device only to equipment which does not carry voltages higher than
253 V AC (50 Hz).
• 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.
• Interconnecting several devices in a single intrinsically safe circuit can result in
different safety characteristic values. This may impair intrinsic safety!
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.
• 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.

Modifications and alterations
DANGER
Explosion hazard due to modifications and alterations to the device!
Non-compliance results in severe or fatal injuries.
• Do not modify or alter the device.
No liability or warranty for damage resulting from modifications and
alterations.
