Line reactors for Basic Line Modules

3.2.1

Description

Line reactors limit low-frequency line harmonics and reduce the load on the semiconductors
in the Basic Line Modules.
A line reactor must be used if several Basic Line Modules are operated in parallel.
A line reactor is not required if a single Basic Line Module is used and the effective supply
impedance equals uk > 3 %.

Safety information

Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
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
• To prevent adjacent components from suffering damage due to these high
NOTICE
Damage to the system caused by the use of inappropriate and not approved line reactors
Inappropriate and not approved line reactors can damage the Line Modules.
Line harmonics that damage/disturb other loads connected to the same line supply can also
occur.
• Only use line reactors that are listed in this Manual.
