1. Brief Introduction
The UPS relay card is available in three models: UF-DRY210,
UF-DRY310 and UF-DRY410, among which, UF-DRY210 and
UF-DRY310 are used with the iTrust series UPS made by
Emerson Network Power Co., Ltd., and UF-DRY410 is used with
the NXr series UPS, EPM series, APS series, GXE, APM150,
APM300, APL (NXP), iTrust Adapt 16/20/30/40kVA UPSs made
by Emerson Network Power Co., Ltd. The relay card should be
installed in the SNMP card slot of the UPS. It is hot pluggable for
easy installation.
The relay card can provide four channels of relay digital signal
output to the remote site. They are UPS on Battery, Battery Low,
UPS on Bypass or in Standby, UPS Faulty. Each dry contact
signal output channel provides both normally open and normally
closed ports. The relay card can also receive three channels of
digital signal input, two of which control the UPS turn-on and
turn-off respectively, the third is reserved.

3. Cable Options
Emerson provides three cable options to connect the DB25
connector of the relay card, to suit the user’s different
requirements on the functions of the connector.
Figures 2 to 7 show the appearance and wiring principle of each
cable.
Note
The iTrust UL33 UPS does not support the digital signal input function
of the relay card.

2. Insert the relay card into the UPS
Note
1. The relay card is hot-pluggable, you can install it without shutting
down the UPS.
2. For the location of the SNMP card slot on the UPS, refer to the user
manual of the UPS.

4. Installation
1) Remove the SNMP card slot cover on the back of the UPS,
save the screws.
2) Align the relay card with the SNMP card slot, insert the relay
card into the slot along the grooves on both sides of the slot.
3) Fix the relay card through the fixing holes on the relay card
panel with the screws obtained in step 1).
3. Connect the cable
You can select an optional cable per your needs, or make the
cable according to Table 1 and Figures 3 through 7. Connect the
cable end with a DB25 male connector to the DB25 connector of
the relay card, and the other end to the user equipment.
Warning
1. The DB25 connector must connect to SELV circuit. Failure to
observe this could cause damage to the relay card and even lead to
safety accidents.
2. The external equipment must meet the electrical parameter
requirement in Table 1, failure to observe this could cause damage to
the dry contact output terminal.
Note
1. The relay card should be installed in the SNMP card slot of the UPS,
which is also used for the installation of the SNMP card. Therefore, if
you use the relay card, you cannot use the SNMP card.
2. Some electronic components on the relay card are sensitive to static
electricity. To prevent static electricity from damaging the adapter, do
not touch its electronic components or circuits, also avoid their contact
with live objects. Please hold the side edges of the relay card when
moving or installing it.
5. Troubleshooting
Fault 1: The dry contact output signal does not change with the
UPS status.
Action to take: Verify the relay card is properly inserted into the
SNMP card slot.
Fault 2: The UPS does not respond to the UPS turn-on dry
contact input signal.
Unpacking inspection
After the relay card arrives, unpack it, take out the delivery list,
and check the goods against it. Should there be any discrepancy,
contact the distributor immediately.
Action to take: Verify bit 8 of the DIP switch of the relay card is
placed in the “ON” position.
Installation procedures
1. Set the DIP switch of the relay card
Skip this step if you need not control the UPS turn-on and turn-off
through the relay card.
The location of the DIP switch is shown in Figure 1. It is an 8-bit
DIP switch. Its factory default setting is shown in Figure 8.
