Screening units should only use anti-interference capacitors that comply with VDE 0565 T1 class X2. These capacitors are switchproof and designed for particularly high switching surges. They can also run directly on mains voltage.A-4Installation direction and relays contact protectionThe resistors used must withstand high voltages (pulse stability). With low resist- ance values in particular, voltage flashovers can occur at the ground helical sec- tion produced in the manufacturing process. For this reason, composite carbon resistors are often used in screening units. However, enamelled wire resistors or cement resistors with a large helical pitch are suitable.Dimensioning guide:The value for C is the direct result of the switching current. The resistance value R can be established by drawing a straight line through the corresponding points on the I and U curves and reading off the resistance at the intersection with the R curve.LoadExample:U = 100 VI = 1 AC is direct result with 0,1 μF
