CARD I/F
Card interface
This is a dual-purpose interface, for connection of Sanyo option cards (LAN interface card,
contact interface card) and for output of UPS status signals.
To use the LAN interface card, set the Interface user setting to Workstation (default setting).
See §3.4 “Setting PC Interface” in the
User Settings Guide for details on the setting
procedure.

Description
AC input error
Active* when UPS is supplying battery power due to failure of
utility power.
Battery low
Active when battery voltage decreases to below the specified
level during battery power supply.
AC output
Active when AC power is being supplied to the UPS OUTPUT
terminals.
Bypass output
Active when bypass power is being supplied to the UPS
OUTPUT terminals.
Device error
Active when a fault occurs in the UPS main unit.
* Active = transistor conduction state
External transmission signal electrical characteristics
• Interface: Transistor open collector output
• Maximum rating: DC +35V/100mA
• Normal state: Open (high impedance); Active state: Conduction
•
When connecting inductive or capacitive loads, do not exceed the maximum rating.
•
When connecting a voltage load, connect - (minus) polarity to the COM (common) pin, and
ensure that the maximum rating is not exceeded. Use in excess of the maximum rating or
connection of applied voltage with the wrong polarity can result in damage to the UPS.
AC voltage cannot be applied.
•
External transmission signals are transistor output. If you require no-voltage contact
(relay contact), use the optional contact interface card.
