Uninterruptable Power Supply (UPS)
Rain Bird recommends the use of a UPS to provide battery backup in cases of fluctuating or loss of
power to the Integrated Control Interface (ICI). When operated by battery the IC System
TM
requires a
“pure sine wave” signal and not a modified, square or PWM wave.
The computer running the Central Control software and ICI should be powered through a UPS. Rain Bird
has verified APC model Smart-UPS 1500 for the IC System. Different countries may have differing
requirements and APC typically makes a Smart-UPS for each country according to the needs of that
country. If sourcing a Smart-UPS for a different country, please source the UPS in the country in which
the system will be operated. For example, do not purchase a Smart-UPS in the United States and ship it
to Asia. The local Rain Bird distributor can source the appropriate UPS in-country.
Less expensive UPS models are available in a variety of stores but it has been proven that these do not
produce the “pure sine wave” signal required by the IC System. Please purchase the APC Smart-UPS
1500 model for an IC System.
