Terminals X21.3 and X21.4
Danger to life when live parts are touched when terminals X21.3 and X21.4 are connected
For operation, the 24 V DC voltage must be connected to terminal X21.3 and ground to
terminal X21.4.
Pulse cancellation is activated if the power supply is disconnected. Regenerative feedback
is deactivated and the bypass relay drops out. If the Line Module is not disconnected from
the line supply when the EP terminal is de-energized, for example, because a line contactor
is not installed, then the DC link remains charged.
Death or serious injury can result when live parts are touched.
• Neutralize the voltage in the DC link.
Damage to the drive electronics when switching the line contactor under load
When switching the line contactor (type according to the recommended selection) under
load, then the contacts will be subject to premature wear. This can cause the contactor to
malfunction, with subsequent damage to the drive electronics.
• Use a leading opening auxiliary contact or use a Voltage Sensing Module (VSM10).
• If this is not possible, then avoid switching the line contactor under load.
