IMPORTANT NOTE: Select wire gauges based on the voltage and current requirements of the
circuitry and the expected length of the wires. The gauge differs for each application.
The external power supply is the sole source of power to the XIO. The power supply may be one of several
different devices, represented as a rectangle in the following drawing.

Description
1 External power supply
2 External power terminal connector
3 XIO device
IMPORTANT NOTE: If you do not use ABB-approved power sources, verify that the customer-
supplied power source meets these requirements. For additional details about requirements, see
section 3.1 Site planning and requirements .
IMPORTANT NOTE: The XIO does not have a hardware circuit to monitor the 12-24V incoming
line voltage like other ABB Totalflow devices. For this reason:
–
The XIO embedded software does not support sleep mode when the line voltage drops
below minimum input value (10.9 V). There is no support for configuration for low power
use.
–
The AGA 3 application always provides a value of 0 V for the XIO Battery / External
voltage.
2.2.5 Security switch
The XIO has a security switch located between the Wireless Antenna Connector and the System Status
LEDs ( Figure 2-11 ).
DANGER – Serious damage to health / risk to life. Explosion Hazard: Once the device is
installed and in operation, the security switch position shall not be changed unless the area is
known to be non-hazardous.
