7.1.1 Visual inspections
The system is safely installed mechanically; there is no risk of injury. All electrical
connections are touch-safe and are marked. A check is also made to determine if
additional warnings need to be incorporated in the documentation.
All surfaces that could become hot are isolated or covered to prevent accidental touch.
NOTICE
Danger of burns
Hot contact surfaces > 55° C are marked with a warning notice. Burns may result if
these surfaces are touched with bare skin.
• Only touch these surfaces when wearing protective gloves.
Check the following:
• Are the surfaces of the system and its components clean and undamaged?
• Is the wiring correct according to VDE and customer specifications (cross-sections
appropriate for current load, manner of routing, cables correctly color-coded,
customer-specific wire markings)?
• Is the tubing routed according to the gas flow diagram in a functionally suitable
manner?
• Have any lines been loosened after transport?
All media connections were marked at the factory and can be easily identified by the
user.
If appropriate for the configured system, notices warning of toxic or asphyxiating gases
have been attached.
