AC input error
This signal is output when there is a power outage or
voltage error of the utility power supply.

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.

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: 50 V DC, 0.1 A

Switches for
independent contact
signals
Setting these switches to “OFF” makes each contact of the external transmission signals
independent.
Refer to contact interface connector

, and set to “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.
