Product Description
The VGLS9901I dry contact card provides dry contact signals for remotely managing the Easy UPS. To meet different application requirement, you set the signal (active open or active close) status on the card by setting jumper. The card is applicable in the following applications:
- IBM servers, PCs, and workstations equipment.
- Automatic control industry equipment and communications applications.
Package Contents
The packaging is recyclable; save it for reuse or dispose of it
properly.
Disclaimer
Schneider Electric is not responsible for damage sustained during reshipment
of this product.
The Dry Contact Card is sensitive to static electricity. When handling the Dry
Contact Card, touch only the end plate while using one or more of these
electrostatic-discharge devices (ESDs): wrist straps, heel straps, toe straps,
or conductive shoes.
Please recycle
The shipping materials are recyclable. Save them for later use, or dispose of
them appropriate.

Pin Assignment
| Pin # | Function | I/O |
|---|---|---|
| 1 | UPS Failure | O/P |
| 2 | UPS Audible Alarm | O/P |
| 3 | GND (Common for Pin 4) | Power Ground |
| 4 | Remote Shutdown | I/P |
| 5 | Common for Relays | Power Supply |
| 6 | Bypass Active | O/P |
| 7 | Low Battery | O/P |
| 8 | UPS On | O/P |
| 9 | Utility Failure | O/P |
P.S. The shutdown pin (pin4 & pin3) only accepts 3-10s high level signal to
perform the UPS shutdown actions after shutdown delay (It depends on UPS
Setting and default setting is 180 seconds). Remote shutdown is only effective
in battery mode, and the UPS will auto-restart at AC recovery. Dry Contact

Note: It’s required to retain the DC current lower than 6mA. Otherwise, it’s necessary to add one resistor within DC current limitation in the serial loop of Remote Shutdown. (e.g. 2K resistor with at least 0.1W rating power). Refer to diagrams in Application.
Installation
Install the dry contact card
You do not need to turn off power to install the dry contact card in a
supported Easy UPS.
The Dry Contact Card is sensitive to static electricity. When handling the Dry
Contact Card, touch only the end plate while using one or more of these
electrostatic-discharge devices (ESDs): wrist straps, heel straps, toe straps,
or conductive shoes.
For the location of the UPS Intelligent Card Slot, see the UPS User Manual.
- Remove the cover of Intelligent Card Slot on the back of the UPS and retain the screws.
- Slide the card into the open slot and secure with the screws from step 1. (See below chart)
- Use one 9-pin cable (not supplied) to connect UPS and equipment to implement the remote monitoring and control.
Settings
Jumper Setup
There are 6 jumpers on this dry contact card. There are AC and AO white silk
printings on the top of each jumper to indicate pin1&2 in A.C and pin2&3 in
A.O.
| Dry contact signal | Jumper setup |
|---|---|
| ACTIVE CLOSE | |
| ACTIVE OPEN |
Jumper function
| Jumper # | Description |
|---|---|
| JP 1 | UPS alarm (P2 on DB-9) |
| JP 2 | UPS on (P8 on DB-9) |
| JP 3 | Bypass (P6 on DB-9) |
| JP 4 | Low battery (P7 on DB-9) |
| JP 5 | Utility failure (P9 on DB-9) |
| JP 6 | UPS failure (P1 on DB-9) |
Internal Circuit Logic
Internal IC controller controls 5 relays for actions 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).
Accordingly, if pin 1 short-circuits with pin 2 via the jumper, the status of
dry contact signal will be ACTIVE CLOSE. Refer to below chart. When the signal
is active, the signal pin on the DB9 connector will connect with the common
pin (pin 5) via the relay. 
If Pin 3 short-circuits with Pin 2 via the jumper, the status of dry contact
signal will be ACTIVE OPEN. Refer to below chart. When the signal is active,
the signal pin on the DB9 connector will disconnect with the common pin (pin
5) via the relay.
