Connection of the Power Unit

Mains Connection of the Supply Unit

• absolutely use a line reactor
• if the dimensioning is not 1:1 --> insert fuses
• in case of interconnected operation with several supply units
consider information sheet 00.R5.0DM-I000 !

Connection of the Braking Resistor

It is absolutely necessary to monitor the braking resistance temperature switch
to record a braking resistance overheat. The overheat may be caused by:
• incorrect dimensioning of the braking resistance
• the input voltage being too high
The current of the brake transistor is monitored additionally. The input thyristors
are switched off in case of a short circuit.
Braking resistors can develop a very high surface temperatures, therefore install
as safe-to-touch as possible!
As standard the evaluation at
terminals T1 and T2 is switched off
and must be activated if necessary
(application mode Pn.12="7").
