Safety Notes
EN
• Electrical circuits with the "Ex i" type of protection can no longer be operated as circuits
EN
with this protection type after being operated with circuits with other types of protection.
EN
• When used in Zone 2 or Zone 22, the device is to be installed in a protective enclosure
or in a cabinet that offers a suitable degree of protection in accordance with
EN
IEC/EN 60079-0.
EN
• An enclosure with at least an IP54 protection rating is required for use in Zone 2
EN
and in safe areas.
• An enclosure with at least an IP64 protection rating in accordance with
EN
IEC/EN 60079-31 is required for use in Zone 22.
EN
• The module may only be mounted on the BusRail 9494.
EN
• Modules with intrinsically safe and non-intrinsically safe field circuits may be operated
simultaneously on one BusRail. In this case, a distance of 50 mm must be maintained
EN
between the terminals with intrinsically safe and those with non-intrinsically safe field
EN
circuits (e.g. partition 220101 or empty space).
EN
• Interconnection of several active, intrinsically safe field circuits can result in deviating
safety-related maximum values. This may endanger intrinsic safety such that
EN
corresponding verification needs to be provided.
EN
• The safety-related maximum values of the connected field devices must match the
EN
values of the modules according to the data sheet, operating instructions or
EU Type Examination Certificate and certificates.
EN
EN
Commissioning, maintenance, repair
EN
• Only have commissioning and repairs performed by qualified and authorised persons
(see chapter "Personnel qualification").
EN
• Before commissioning, make sure that the device is not damaged.
EN
• Perform only maintenance work described in these operating instructions.
EN
• Modules and plug connectors may be connected and disconnected during operation
EN
in hazardous areas (hot swap and hot plug).
• Always clean the device with a damp cloth to prevent electrostatic charge.
