Relay output
Relay is not suitable for direct switching of a electromechanical holding brake!
Use a corresponding suppressor circuit in case of an inducve or capacive
load!
Connecon Terminal X9: COM Centre contact (common)
Terminal X9: NC Normally-closed contact
Terminal X9: NO Normally-open contact
Minimum DC contact load
Voltage V 10 A correct switching of the relay contacts
needs both values to be exceeded simultane-
ously.

PTC input
In the Lenze seng, motor temperature monitoring is acvated! In the delivery
status, there is a wire jumper between the terminals T1 and T2. Before connect-
ing a thermal sensor, remove the wire jumper.
