3.6 Safety information for operation

Only operate the devices if they are clean and undamaged. If a device is in any way
damaged, do not touch it to avoid injury. In the case of any damage that may compromise
ingress protection (e.g. cracks, holes or broken components) the devices must be taken out
of commission immediately. Before the device is recommissioned the damaged
components must be replaced.

If the devices are to be used in category 2D/3D or EPL Db/Dc dust deposits thicker than
5 mm must be removed. You must ensure that no high-energy loading mechanisms at the
operating surface of the keyboards and pointing devices (e.g. pneumatic particle transport)
occur during operation. Do not use the keyboards and pointing devices in environments
where propagating brush discharges may occur.

In case of non-compliance with or contravention of the above explosion-protection is no
longer guaranteed and all warranty claims shall be null and void.
3.7 Residual risks
3.7.1 Explosion hazard
Despite the device's state-of-the-art design, explosion hazards cannot be entirely eliminated in
hazardous areas.

Perform all work steps in hazardous areas with the utmost care at all times !
Possible hazards ("residual risks") can be categorised according to the following causes:
Mechanical damage
The device may become damaged during transport, mounting or commissioning. This kind of
damage may, for example, render the device's explosion protection partially or completely
ineffective. This may result in explosions causing serious or even fatal injury.

Do not commission a damaged device.

Only transport the device in special transport packaging that reliably protects the device
from external influences. Take ambient conditions into account when selecting the transport
packaging (see chapter
16.1 Technical data ).

Do not place any loads on the device.

Check the packaging and the device for damage. Immediately report any damage to
R. STAHL.

Store the device ideally in its original packaging in a dry place (with no condensation), and
make sure that it is stable and protected against the effects of vibrations and knocks.

Do not damage the device or seals during its installation.
Excessive heating or electrostatic charge

Operate the device only within the prescribed operating conditions (see chapter
4.4 Markings on the device and chapter 16.1 Technical data ).

Mount and install the device in such a way that it is always operated within the permissible
temperature range.

Do not use the device in strong charge-generating environments.

Avoid friction and flow of particle streams.
