The PROFIBUS Fiberoptic Repeater in plastic or stain-
less steel protective housing is intended for use in explo-
sive hazardous area.
The PROFIBUS Fiberoptic Repeater (DIN-rail module)
without plastic or stainless steel protective housing must
be used only as a replacement for a defective PROFIBUS
Fiberoptic Repeater in plastic or stainless steel protective
housing. Another use is possible after joint ATEX
approval with an approved protective housing.
The PROFIBUS Fiberoptic Repeater is used as an inter -
face between electrical PROFIBUS signals from the
explosive hazardous area (ex-area) and the safe area
(non-ex-area). Bus and auxiliary power circuits are isolat-
ed galvanically.
PROFIBUS Fiberoptic Repeater are intended for use in
the optical PROFIBUS networks. They enable implemen-
tation of electrical PROFIBUS interfaces (RS 485 level) in
optical PROFIBUS interfaces and vice-versa.
By using the known advantages of the optical transmis-
sion technology, the devices can be integrated in the
existing PROFIBUS fieldbus networks. Likewise, com-
plete structure of a PROFIBUS fieldbus network with
devices in line, star and ring topology is possible in any
combination.
Applicable laws, standards or guidelines must be
observed for usage or the planned purpose. The devices
are approved only for proper and intended use. Any
guarantee and producer responsibility becomes void in
case of infringement.
The devices are not suitable for separation of signals in
power measurement, unless stated specifically in the
appropriate data sheet.
Protection of operating personnel and system is not
guaranteed if the component is not used in accordance
with its intended purpose.
1.6 Intended use
1.7 Assembly
1.7.1 General information on assembly
Familiarise yourself with the device prior to assembly,
installation and startup and read this manual carefully.
The device must not be installed on places with aggres-
sive vapours.
Observe BGR A3 (the Federal Institute for Geosciences
and Natural Resources) when working under voltage.
Installation requirements in accordance with IEC/EN
60079-14 / IEC/EN 60079-25 and national deviations
must be com plied with.
The devices are designed for use in pollution degree 1
and overvoltage category II as per IEC/EN 60664-1 .
If devices are used in general electrical systems, these
must not be used thereafter in electrical systems, which
are connected to explosive hazardous areas.
The in-built PROFIBUS Fiberoptic Repeater in ex-e-
housing contains non-intrinsic circuits. The non-intrinsic
circuits must be covered so that the optical fibre connec-
tions are accessible during ongoing operation. The cover
must attain protection class IP30 as per IEC/EN 60529.
The devices are designed according to protection class
encapsulation as per IEC/EN 60079-18. The housing, the
seal and the sealing agent must not be damaged.
The equipment must not be operated with dust deposits
>
_ 5 mm thickness as per IEC/EN 61241-1. Terminals in
increased safety are covered. The cover may be removed
any time during assembly in safe area.
The device types can be installed outside the ex-area.
The housing cover may be opened for servicing during
ongoing operation.
Non-used inlet openings are to be sealed securely with
certified sealing plugs in order to comply with the IP pro-
tection class. Likewise, seal inserts appropriate for the
respective cable diameter must be used.
