Outputs status information of the UPS such as a power outage or voltage drop.
External Transmission Signals and Shutdown Input Signals
Signal Name
This signal is output when there is a power outage or
AC input error
voltage error of the utility power supply.
This signal is output when the battery voltage drops
Battery voltage drop
to or below the specified value (approx. 178 V).
This signal is output when AC output is being

supplied to a load device.
This signal is output when inverter output is being
Inverter output
supplied to a load device.
This signal is output when the utility power supply is
Bypass output
being supplied from the bypass circuit.
Device error
This signal is output when a device error occurs.
The UPS is shut down as a result of receiving 5 V DC
(pulse signal of at least 4 sec.) during battery
operation when there is a power outage. Current
flows at approximately 5 mA when the power is on.
UPS shutdown
This is enabled when the interface is set to
Standalone. For the setting procedure, see §3.5
"Setting PC Interface" in the
Manual.
External Transmission Signals and Electrical Characteristics
Interface: Relay non-voltage contact signal
Contact rating: 100 V AC / 50 V DC, 0.1 A
Note
When connecting an inductive/capacitive load, make sure the contact rating is not exceeded.

Switches for independent contact signals (see ④)
Setting these switches to "OFF" makes each contact of the external transmission signals
independent.
Refer to contact interface connector ③, and set "ON" or "OFF" according to how the UPS will
be used by the customer. The switches are all set to "ON" at the time of shipment from the
factory.
