DANGER
Danger of fatal injury due to electric shock!
Unconnected or incorrectly installed protective conductor systems can generate hazardous voltages and cause electrical
shocks resulting in serious accidents.
•
Work may only be carried out by qualified specialists.
•
Implement protective conductor systems in accordance with DIN EN 60204-1, Section 8.2.
•
Every single part of the electrical equipment must be connected to the protective conductor system.
•
Never interrupt the protective conductor system if electrical equipment is attached to covers, doors or covering plates.
•
If parts are removed, e.g. during maintenance work, make sure that the protective conductor system is not interrupted
for the remaining parts.
DANGER
Risk of injury and fire due to electric arcs!
Electric arcs, dangerous voltages and electric shocks may occur when disconnecting and plugging in the connectors of the
mains connection under load or voltage.
•
Never plug or unplug mains connectors under voltage.
•
Switch off the power supply and secure against switching back on before working on the mains connection.
•
Work on the connectors must only be carried out under sufficient lighting.
WARNING
Risk of fire!
Risk of fire due to too small cable cross-sections. A too small cable cross-section will result in overheating of the cable.
•
Lay cable cross-sections according to the current consumption of the unit and the length of the cable.
•
Protect the power cable with the upstream fuse specified on the type plate and in the technical data.
