Battery voltage
This signal is output when the battery voltage drops

This signal is output when the utility power supply
Bypass output
is being supplied from the bypass circuit.
Device error
This signal is output when a UPS 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: AC100V/DC50V, 0.1A
Note
When connecting an inductive/capacitive load, make sure the contact rating is not
exceeded.

Switches for independent 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.
