DESCRIPTION
MultiCOM 392 is a device that, inserted in the proper slot of the UPS, provides 8 configurable dry contact outputs and up to four
inputs for the control and monitoring of the UPS.
The device is compatible with the following UPS series:
•MST / MSM / MCT / MCM
•C1T / C1M
•GMI
•S3T / S3M / S3U
•MPW
Refer to the code on the UPS data plate to trace back to the UPS model you own (ex. P/N: DS3TK10...).

8
INPUTS
The four inputs, IN1 / IN2 / IN3 / SWMB, can be configurable or not according to different UPS series. Check the features that are
compatible and the default configuration in the chapter dedicated to your UPS model.
Some UPS may not handle all inputs.
OUTPUTS
For all UPS series, each of the eight outputs (OUT1 –OUT8) can be associated with an event such as an operating state or a
UPS alarm condition. You can also configure the function logic of the relay and set a delay for the event signalling.
The outputs can be configured via the configuration software of the UPS.
Check the default configuration of the outputs in the chapter dedicated to your UPS model.
In order to know the events that can be associated with the outputs, refer to the configuration software of the UPS.

SERIES MST / MSM / MCT / MCM
For series MST / MSM / MCT / MCM, MultiCOM 392 is compatible only if the UPS is provided with the interface
board mounted B0056 Rev.01C / B0056 Rev.02C or higher.

CAUTION
ALL OPERATIONS DESCRIBED IN THIS CHAPTER MUST
ONLY BE CARRIED OUT BY PERSONNEL WHO ARE
QUALIFIED AND PROPERLY TRAINED
All the operations listed below must be carried out while the UPS is completely disconnected from the mains and
from the batteries and with all disconnectors and fuse holders open.
Refer to the relative user manual to turn off the UPS. Then wait about 15 minutes to allow the internal capacitors to
discharge.
•Remove the top UPS panel in order to access to the interface board of the UPS.
•Set the jumpers JP3 and JP4 of the interface board referring to the following table and image.
•Replace the top panel of the UPS.
•Perform the safety tests (see following pages).

SAFETY TESTS
CAUTION
ALL OPERATIONS DESCRIBED IN THIS CHAPTER MUST
ONLY BE CARRIED OUT BY PERSONNEL WHO ARE
QUALIFIED AND PROPERLY TRAINED
The tests described below should be performed after the UPS is completely closed with the wrapping and all the panels. In
addition, all operations must be carried out with the UPS off and completely disconnected from themains, batteries and any other
equipment.
▪Equipment required
1. Earth resistance meter, fitted with RS28 ELEKTROTECHN Laboratorium electrodes (or similar).
2. UH28 .. ELEKTROTECHN LABORATORIUM strength test instrument complete with high voltage rectifier BRIDGE
adapter (or similar).
▪Measurement of contact resistance to earth (CRITICAL FOR SAFETY)
Connect one electrode from the “RS 28” generator to the earth terminal. Inject the test current through the other electrode
(tip) in all the different parts that make up the metal frame. In the test on painted frames, before the test, pierce the painted
layer with the tip.
The test is passed if all the metal parts of the equipment are earthed.
The earth resistance reading on the instrument should be 0.1 Ohm.
▪Strength test (CRITICAL FOR SAFETY)
With theUPS off and disconnected from themains, batteries and any other equipment, short circuit themainsinput terminals
(L1, L2, L3, N) (and bypass input terminals if present).
Close all the disconnectors SWIN, SWOUT, SWBATT (if present on the UPS), and SWMB and SWBYP (if present). With
the machine for the strength test and relative rectifier bridge, set at 1500Vac with a 10mA limit, apply a voltage of about
2100Vdc for at least 2 seconds between the short circuit created beforehand and an earth terminal.
The test is passed if the test equipment gives no indication of an anomaly.
Remove the short circuit between the phases and the neutral. Open all the disconnectors.

▪Remove the cover of the UPS slot dedicated to the contacts boards (AUX RELAY SLOT) by removing the two retaining
screws.
▪Wire appropriately MultiCOM 392.
▪Insert MultiCOM 392 in the slot dedicated to the contacts card (AUX RELAY SLOT).
▪Fix the cover provided with the MultiCOM 392 using the screws previously removed.

CONFIGURATION
MultiCOM 392 can be configured using the configuration software of the UPS.
Before setting the input/output, you must select “Multicom 392 [8out]” for I/O card model.
INPUT
DESCRIPTION
IN1
REMOTE ON: By closing the contact for at least 3 seconds, the UPS will switch on.
IN2
REMOTE OFF: By closing the contact, the UPS will immediately switch off.
This feature is disabled by default. To use it you must disable the corresponding feature
available on the AS400 port of the UPS (see “Jumper settings on interface board of the UPS”
and “Jumper settings and installation of the MultiCOM 392”).
IN3
CONFIGURABLE INPUT: use the UPS configuration software to select the function that has to be
associated with IN3 (Input 3 mode default: Load on bypass).
SWMB
Manual bypass auxiliary contact (for the management of an auxiliary contact of a possible remote
bypass). The auxiliary contact must be anticipated type, normally open.
The transition takes place regardless of the status of the bypass line and of the bypass/inverter
sync.
The inputs IN1 / IN2 / IN3 have to be used as alternative to the corresponding inputs on the AS400 port of the UPS.
