Line Modules Booksize4.4 Active Line Modules with cold plateBooksize Power UnitsManual, (GH2), 04/2014, 6SL3097-4AC00-0BP6 1994.4 Active Line Modules with cold plate4.4.1 DescriptionActive Line Modules generate a constant, regulated DC voltage in the DC link from the 3-phase line supply voltage that supplies the connected Motor Modules with power.This ensures that they are not influenced by line voltage fluctuations.When the motors are in feedback mode, Active Line Modules supply power back to the linesupply. The regenerative feedback capability of the modules can be deactivated byparameterization.The DC link starts precharging as soon as the line voltage is applied and is independent ofits phase sequence direction. Load can be applied to the DC link after the module has beenenabled. An optional main contactor is required for disconnecting the voltage.Active Line Modules can be directly connected to TN, IT and TT systems. The Line Moduleshave an integrated overvoltage protection function.WARNINGDanger to life if the fundamental safety instructions and remaining risks are not carefullyobservedIf the fundamental safety instructions and remaining risks in Chapter 1 (Page 25) are notobserved, accidents involving severe injuries or death may occur.• Adhere to the fundamental safety instructions.• When assessing the risk, take into account residual risks.Artisan Technology Group - Quality Instrumentation ...
