Safety Notes
EN
• Modules and plug connectors may be connected and disconnected during operation
EN
in hazardous areas (hot swap und hot plug).
EN
• When used in Zone 1, 2, 21 or 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
EN
Zones 1 and 2.
• An enclosure with at least an IP64 protection rating in accordance with
EN
IEC/EN 60079-31 is required for use in Zones 21 and 22.
EN
• The device is intended for installation in areas with a degree of pollution of 1 or 2 as
EN
defined in IEC/EN 60664-1.
• The module may only be mounted on the BusRail 9494.
EN
• Modules with intrinsically safe and non-intrinsically safe field circuits may be operated
EN
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
circuits. (e.g. partition 220101 or empty space).
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
EN
examination certificate.
• Interconnections of several active intrinsically safe circuits can result in different
EN
safety-related maximum values. This may endanger intrinsic safety such that
EN
corresponding verification needs to be provided.
EN
Commissioning, maintenance, repair
EN
• Only have commissioning and repairs performed by qualified and authorised persons
EN
(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.
• Always clean the device with a damp cloth to prevent electrostatic charge.
