5 Safety regulations and installation
notes
5.1 Installation notes
• The category3 device is designed for installation in
zone2 potentially explosive areas. It meets the
requirements of EN60079-0:2012+A11:2013 and
EN60079-15:2010.
• Installation, operation, and maintenance may only be
carried out by qualified electricians. Follow the
installation instructions as described.
• When installing and operating the device, the
applicable regulations and safety directives (including
national safety directives), as well as general technical
regulations, must be observed. The technical data is
provided in the package slip and on the certificates
(conformity assessment, additional approvals where
applicable).
• The device must not be opened or modified. Do not
repair the device yourself, replace it with an equivalent
device. Repairs may only be carried out by the
manufacturer. The manufacturer is not liable for
damage resulting from violation.
• The IP20 protection (IEC 60529/EN 60529) of the
device is intended for use in a clean and dry
environment. The device must not be subject to
mechanical strain and/or thermal loads, which exceed
the limits described.
• To protect the device against mechanical or electrical
damage, install it in a suitable housing with appropriate
degree of protection as per IEC60529.
• The device is not designed for use in atmospheres with
a danger of dust explosions.
• If dust is present, it is necessary to install into a suitable
approved housing, whereby the surface temperature of
the housing must be taken into consideration.
5.2 Installation in Zone 2
• Observe the specified conditions for use in potentially
explosive areas! Install the device in a suitable
approved housing (with a minimum of IP54 protection)
that meets the requirements of EN 60079-15. Observe
the requirements of EN 60079-14.
• In zone2, only connect devices to the supply and signal
circuits that are suitable for operation in the Ex zone 2
and the conditions at the installation location.
• In potentially explosive areas, terminals may only be
snapped onto or off the DIN rail connector and wires
may only be connected or disconnected when the
power is switched off.
• The switches of the device that can be accessed may
only be actuated when the power supply to the device is
disconnected.
• The device must be stopped and immediately removed
from the Ex area if it is damaged, was subject to an
impermissible load, stored incorrectly or if it
malfunctions.
WARNING: Risk of electric shock
– Provide a switch/circuit breaker close to
the device, which is labeled as the
disconnect device for this device or the
entire control cabinet.
– Disconnect the device from all power
sources during maintenance work and
configuration (the device can remain
connected to SELV or PELV circuits).
– The housing of the device provides a
basic insulation against the neighboring
devices, for 300 V eff. If several devices
are installed next to each other, this has
to be taken into account, and additional
insulation has to be installed if necessary.
If the neighboring device is equipped with
basic insulation, no additional insulation
is necessary.
WARNING:
Observe the following safety notes when
using the device.
WARNING: Explosion hazard when used
in potentially explosive areas
Please make sure that the following notes and
instructions are observed.
