General safety guidelines
Before switching on, live parts must be securely covered. All covers must be kept closed during operation.
2.6.2 Ambient conditions - Dust, moisture, aggressive gases
The use of operating and monitoring devices (e.g. industrial PCs, Power Panels, Mobile Panels, etc.) and unin-
terruptible power supplies in dusty environments must be avoided. This can otherwise lead to dust deposits that
affect the functionality of the device. Sufficient cooling may then no longer be ensured, especially in systems with
an active cooling unit (fan).
The presence of aggressive gases in the environment can also result in malfunctions. In combination with high
temperature and relative humidity, aggressive gases – for example with sulfur, nitrogen and chlorine components
– trigger chemical processes that can very quickly impair or damage electronic components. Blackened copper
surfaces and cable ends in existing installations are indicators of aggressive gases.
When operated in rooms with dust and condensation that can endanger functionality, operating and monitoring
devices such as Automation Panels or Power Panels are protected on the front against the ingress of dust and
moisture when installed correctly (e.g. cutout installation). The back of all devices must be protected against the
ingress of dust and moisture, however, or the dust deposits must be removed at suitable intervals.
