POWER SUPPLY WIRING

When not directly supplied from mains (type PM), the external power supply must be an
approved ELV source, insulated from AC mains by double / reinforced insulation per CSA
C22.2 No. 61010-1 / UL61010-1 / EN/IEC 61010-1.
The F073-T can be powered from an external power supply. An internal power supply is also
available in the form of a lithium battery. When both external and internal power supplies are
available, the internal power supply is interrupted and will act as a backup supply. Note that the
optional backlight only works with an external power supply.
