External signal I/O connections for
various gateways are provided on the
right side of the instrument. You can
connect the instrument to an
uninterruptible power supply, alarm
output, LAN, and bar code reader from
these gateways. Each gateway is
explained below.
● Power-outage detection signal
You can connect an uninterruptible power supply (UPS) to the instrument’s power supply so that
tissues can be preserved and evacuated in case of power outage. When installing an UPS, be sure to
use a model with an output capacity equivalent to or greater than the input rating of the instrument.
Recommended UPS rating: Capable of outputting 15 kVA for 5 minutes
Some UPSs are not supported by the instrument. For details, contact the Sakura Finetek Technical
Support representative or local representative. The instrument provides an UPS input signal to detect a
power outage mode of the UPS connected to the power supply. Use an UPS equipped with a contact-
output interface or open-collector output that remains open in normal state and shorts upon power
outage. Always turn off the instrument power before connecting an UPS.
* When connecting the power-outage detection signal to an external circuit, loop the signal cable
around the attached ferrite core at a point as close as possible to the instrument, as shown below. If
the ferrite core is not installed, the instrument may malfunction due to external noise.
