Danfoss iC7-Automation - Thermistor Input; Control Cable Routing

Design Guide | iC7-Automation Air-cooled Enclosed Drives Control and Option Installation
Table 27: 24 V DC Voltage Output (continued)
Parameter Value
Short Circuit Current 250 mA
Electrical fast transient (EFT) 2 kV
7.7.8 Thermistor Input
The I/O and Relay Option contains 1 thermistor input. Thermistor input has basic isolation for system voltages ≤ 600 V and reinforced
isolation for system voltages ≤ 300 V (OVC III 3000 m). For system voltage of 600 V, supplementary insulation is necessary at the motor
end.
