6 Installation and Setting-to-Work
For the installation, maintenance and cleaning of the units, it is
absolutely necessary to observe the ordinances and provisions
concerned with explosion protection (EN 60079-14, EN 50014-50039) as
well as the Accident Prevention Regulations (UVV).
Installation, maintenance and cleaning of the units must only be
performed by persons trained and authorized for this purpose, insofar
as they are familiar with the units.
Modifications and conversions to the units are not permissible and will
cause the Ex protection and the garantee to become void.
E.L.B. Ex-Geräte Bachmann GmbH is not liable for any subsequent
damage.
6.1 Preparatory Work
Before connecting the mains supply, check the units installed in the
enclosure. In particular, ensure that there is an adequate flow of air
around the units and that any unit casings can be purgeed properly.
Furthermore, ensure that the electrical units are de-energized if there is
any loss of pressure.
This includes the isolation of any data lines.
6.2 Installation
It is permissible to mount the EEx-p system F-350 on or in any casing which is suitable for
applications with overpressure (but at least IP 54).
The wall thickness of the casing should not exceed 4 mm.
6.2.1 EEx-p System F-350
The EEx-p system F-350 consists of the monitoring unit F-351, the digital/ proportional
controllers of the series F-220 and a pressure regulator. The areas of application for the
various digital/proportional controllers are given in Section 9.2.2 Digital/ Proportional
