(for Residential and industrial areas)

Cable:

Wire cross-section*: 20 AWG-14 AWG (0.5-2.0 mm2)
- Protection class I: H05VV-F or similar
- Protection class III: LiYY or similar

*) Note: Wire cross-sections must be chosen according to actuator power consumption and line length, such as the voltage supply to the actuator does not go below 20.4 VAC/VDC (24 VAC/VDC minus 15%).
In case of VDC input signal on a 24 VAC/VDC powered actuator, the voltage drop on neutral line must be smaller than the defined hysteresis level for the VDC input signal.
