TERMINAL 4-5: POWER SUPPLY - TYPE PX (DEFAULT) AND PD (OPTION)

To power the F050-A an internal battery can be used (type PB) and / or an external DC power
supply of 8-30V DC (type PX) or 16-30V DC (type PD). Connect the "-" to terminal 4 and the "+" to
terminal 5.
When power is applied to these terminals, the optional internal battery will be disabled / enabled
automatically to extend the battery life time.
