2Product Introduction
The AS400 communication card provides contact closures for remote monitoring
your UPS. To meet different application requirement, the AS400 card is capable of
selection the status of the dry-contact signal (active close or active open) by setting
jumper. This suitable applications are listed below:
IBM Server, Personal PC & Workstations equipments
Auto-controlled industrial equipment & communication applications
Step 1: Remove cover of Intelligent
Slot on the rear panel of the UPS.
Cover of
Intelligent Slot
Step 2: Insert AS400 card into Intelligent
Slot.
Step 3: The cover of AS400 should attach
close to the rear panel. Using screwdriver,
secure the AS400 to the UPS chassis with
2 screws.
Step 4: Use the 9-pin communication
cable to connect UPS and equipment to
implement the remote monitoring and
control.

Function Description
P.S. The shutdown pin (pin4 & pin3) only accepts 3-10s high level signal to perform
the UPS shutdown.

Note: It’s required to retain the DC current lower than 6mA. Otherwise, it’s
necessary to add one 2Kresistor with at least 0.1W rating power in the serial loop
of Remote Shutdown to limit the resistor current. Refer to Figure 1.

Below shows the circuit of basic application to implement
monitoring and control.
Application:
User Interface
IC controller of the card controls actions of 5 relays depending on the UPS status.
Active-Close(A.C) terminal and Active-Open(A.O) terminal of each relay
connect to pin 3 and pin 1 of a 3-pin connector respectively. The pin 2 of
the 3-pin connector connects to the signal pin of the DB9 interface connector.
The 2-pin jumper can be plugged to the 3-pin connector to either short-circuit
Pin1 & Pin2(A.C) or short-circuit Pin3 & Pin2(A.O).
Fig 2 Connection for ACTIVE CLOSE
Accordingly, if pin1 short-circuits with pin2 via the jumper, the status of dry contact
signal will be ACTIVE CLOSE, refer to Fig 2. When the signal is active, the signal pin
on the DB9 connector will connect with the common pin (pin5) via the relay.
Fig 1 Pin definition and internal logical connection
If pin3 short-circuit with Pin2(A.O) via the jumper, the status of dry contact signal
will be ACTIVE OPEN, refer to Fig 3. When the signal is active, the signal pin on the
DB9 connector will disconnect with the common pin (pin5) via the relay.
Fig. 3 Connection for ACTIVE OPEN
The 3-pin connectors can be easily
found just near to the relay. Refer
to Fig. 4.
There are AC and AO white silk printings
of the connector as shown in Fig. 5 to
indicate pin1&2 in A.C and pin2&3 in A.O.
Fig. 5 AO and AC silk printings
indicates each 3-pin connector status
Fig.4 AS400 card
To achieve ACTIVE CLOSE dry-contact
signal, the jumper should connect
the 2 pins(Pin1&2) as shown in Fig. 6.
Fig. 6 Jumper setting
for ACTIVE CLOSE
To achieve ACTIVE OPEN dry-contact signal,
the jumper should connect the middle pin
and the pin3 as shown in Fig. 7
