AC supply models
Mains powered Ax
O2NE+™/Safe-Ox+™'s are pre-wired with a mains cable, fitted with a plug
suited to the destination country. Where internal plug fuses are fitted, these are 3 amp. Ensure
that the unit is connected to the correct supply voltage (i.e. 110 or 230V AC). Where no fuse is
fitted in the plug, the instrument should be powered from a 3 amp fused outlet. The Ax
O2NE+™/Safe-Ox+™ is fitted with an internal fuse, which is rated at 500mA.

O2NE+™/Safe-Ox+™ 's require a DC supply in the range 9-24V DC. A 2m
cable is factory fitted to the instrument. The DC supply should be connected to this cable as
follows:
1)
Blue wire negative (0Volts)
2)
Red wire positive (9 to 24Volts)
