Safety instructions for line filters
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 filter, use touch protection according to IPXXA or corresponding to the local
installation regulations.
Risk of burns due to high surface temperatures of the line filter
The line filter can become very hot. You can get seriously burnt when touching the surface.
• Mount the line filter so that contact is not possible. If this is not possible, attach a clearly
visible and understandable warning notice 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 filter.
Line filter damage by connecting to impermissible line supplies
Line filters are only suitable for direct connection to TN line supplies. Damage will occur if
the line filter is connected to other line supplies.
• Only connect the line filter when TN line supplies are being used.
Line filter damage due to interchanged connections
The line filter will be damaged if the input and output connections are interchanged.
• Connect the incoming line supply cable to LINE L1, L2, L3.
• Connect the outgoing line to line reactor at LOAD L1´, L2´, L3´ (U, V, W).
