Safety instructions for line reactors
Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 25) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Danger to life due to electric shock in the event of missing touch protection
Death or serious injury can result when live parts are touched.
• For the line reactors, use touch protection according to IPXXA or corresponding to the
local installation regulations.
Danger to life due to high voltages on the additional winding of the HFD line reactor
If system oscillations do occur and no damping resistor is connected, impermissibly high
voltages may arise on the additional winding of the HFD line reactor.
Death or serious injury can result when live parts are touched.
• Connect a damping resistor to the HFD line reactor.
Risk of burns due to high surface temperature of the line reactor
The line reactors can become very hot. You can get seriously burnt when touching the
surface.
• Mount the line reactors so that contact is not possible. If this is not possible, attach
clearly visible and understandable warning notices at hazardous positions.
• To prevent adjacent components from suffering damage due to these high
temperatures, maintain a clearance of 100 mm on all sides of the line reactors.
