Installation, commissioning
In order to comply with the requirements acc. to EN 61241-1 and EN 60079-15, the following
prerequisites must be met:
• Devices with connector must be equipped with an additional safeguard or a mechanical
interlocking guard to avoid unintended separation of the connector. The warning sign
"Do not disconnect under voltage" that is supplied with the device must be attached to
the device or its mounting bracket so that it is clearly visible.
• Devices with terminal compartment lid must only be commissioned if the terminal
compartment lid of the device is properly sealed.
• Connection cables and connectors must be protected from excessive pulling or pushing
strain.
• The requirements according to EN 61241-1 regarding dust deposits and temperatures
must be observed.
Attention!
• Due to the physical circumstances, the devices must not be used for the protection of
persons or for purposes of emergency shutdown.
• The sensors must only be installed and maintained by trained electricians.
• The applicable regulations for the installation of electrical equipment in potentially
explosive areas must be observed.
• Operation of the RFM 32 SL 200 Ex n in potentially explosive areas is recommended
only in combination with the TFM 0x 1x10.EX transponders from Leuze electronic,
which are approved for use in potentially explosive areas!
Repairs, maintenance
No changes may be made to the devices designed for potentially explosive areas.
Repairs to the devices may only be performed by persons trained for such work or by the
manufacturer. Defective devices must be replaced immediately.
Cyclical maintenance of the devices is not necessary.
Depending on the environmental conditions, it may occasionally be necessary to clean the
antenna surface of the devices. This cleaning must only be performed by appropriately
trained persons. We recommend using a soft, clean cloth for this purpose. Cleaning agents
containing solvents must not be used!
Chemical resistance
The read/write systems and the TFM 0x 1x10.EX transponders demonstrate good resis-
tance against many diluted acids and bases.
Exposure to organic solvents is possible only under certain circumstances and only for short
periods of time.
Resistance to chemicals should be examined on a case by case basis.
