SMA SC 500CP XT Installation - Manual (Page 11)

Risk of fire due to failure to observe torque specifications on live bolted connections
Failure to follow the specified torques reduces the ampacity of live bolted connections so that the contact resistances
increase. This can cause components to overheat and catch fire.
• Ensure that live bolted connections are always tightened with the exact torque specified in this document.
• When working on the device, use suitable tools only.
• Avoid repeated tightening of live bolted connections as this may result in inadmissibly high torques.
Risk of burns due to hot components
Some components of the product can get very hot during operation. Touching these components can cause burns.
• Observe the warnings on all components.
• During operation, do not touch any components marked with such warnings.
• Wear suitable personal protective equipment for all work on the product.
