Power supply – 4-wire device
A safety certified power supply which provides double insulation between the primary
and output must be used for powering the unit. The power supply must be a limited
power source type with maximum output current 1A and voltage range of 20VDC
minimum and 32VDC maximum, and not to be connected to a DC distribution network.
