3.4.3.7 X21 EP terminals
Table 3-30 Terminal block X21
Terminal Designation Technical specifications
1 + Temp
2 - Temp
Temperature switch type: Bimetallic-element switch
with NC contact
Response threshold of the temperature input:
Temperature at the braking resistor in the operating
range → Resistance value ≤ 100 ohm
Overtemperature at the braking resistor → Resistance
value > 100 ohm
Fault reactions: Output of an error warning and
deactivation of the Basic Line Module after one minute,
if overtemperature is still present at the braking
resistor.
It is impermissible to apply a voltage at this input.
1)
If there is no braking resistor, terminals 1 and 2 must
be jumpered to deactivate overtemperature.
3 EP +24 V (enable pulses)
4 EP M (enable pulses)
Voltage 24 V DC
Current consumption: 10 mA
Isolated input
Signal propagation times:
L → H: 100 μs
H → L: 1000 μs
Max. connectable cross-section: 1.5 mm
2
Type: Screw terminal 1 (see Connection Methods)
1)
only applies to 20 kW and 40 kW Basic Line Modules
WARNING
For operation, 24 V DC must be connected to terminal 3 and ground to terminal 4. When
removed, the bypass relay drops out. If the Line Module is not disconnected from the line
supply when the EP terminal is deactivated (e.g. a main contactor is not installed), the DC
link remains charged.
DANGER
If the temperature switch is not connected, this can cause the resistor to overheat.
