AC input error
This signal is output when there is a power outage or
voltage error of the utility power supply.
1-8: ON
2-8: OFF
Battery voltage drop This signal is output when the battery voltage drops
to or below the specified value (approx. 178 V).
3-11: ON
AC output
This signal is output when AC output is being
supplied to a load device.
4-7: ON
15-7: OFF
Inverter output
This signal is output when inverter output is being
supplied to a load device.
14-8: ON
Bypass output
This signal is output when the utility power supply is
being supplied from the bypass circuit.

UPS shutdown
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.
This is enabled when the interface is set to
Standalone. For the setting procedure, see §3.5
“Setting PC Interface” in the
LCD Panel Operating
Manual.

External Transmission Signals and Electrical Characteristics
Interface: Relay non-voltage contact signal
Contact rating: 100 V AC / 50 V DC, 0.1 A
Terminal Names External Appearance

Switches for
independent contact
signals
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.
External Appearance
When all of
1 to 4 are in
the “ON” state
Set them to “OFF” when using each contact signal as an
independent circuit.
Set them to “ON” when using each contact signal as a common
COM circuit.
When connecting an inductive/capacitive load, make sure the contact rating is not exceeded.
