• Terminal type: Spring-loaded terminal
• Type: PELV 24 V circuit
• Voltage tolerance of the P24 V ext: 18 V to 30 V
• Current consumption:
– for the 30 kW device, In = 5 A
– for the 120 kW device, In = 20 A
• Conductor cross-sections: 1.5 to 2.5 mm²
For the 120 kW device, for connections "P24_EXT" and "M24_EXT", a cross-section of 2.5 mm² must be used.
1)
Contact rating of the "NO contact for the contactor control": 2 A at 30 VAC/DC resistive.
NOTICE
Material damage when the maximum voltage rating of the NO contact for the contactor
control is exceeded
When the maximum voltage rating is exceeded, the NO contact for the contactor control
can be damaged.
• Do not apply a voltage higher than 30 V to the NO contact for the contactor control.
