Danger to life caused by high leakage currents when the external PE conductor is
interrupted
Drive components conduct high leakage currents through the PE conductor. When the PE
conductor is interrupted, touching live components can result in electric shock, which can
lead to death or serious injuries.
• Ensure that the external PE conductor complies with at least one of the following
Danger of fire due to overheating if improperly installed
Improper installation can result in overheating with a hazard to persons due to smoke and
fire. Further, increased failures can occur and the service life of units/systems may be
shortened.
• Always install the Power Modules vertical with the line and motor connections below.
• Ensure a 1-mm clearance between mounted components.
• Ensure the following ventilation clearances above and below the component:
• Only install devices in this area that do not obstruct the flow of cooling air.
• Ensure that the cooling air can flow through the Power Modules unobstructed.
