Safety and warning notes
WARNING
– Explosion Hazard Do not disconnect Equipment
unless power has been switched off or the area is known to be non-
hazardous.
WARNING
– Explosion Hazard. Substitution of components may
impair suitability for class I, Division 2.
WARNING
– Switch off the system before connecting the module. Never work
on the machine when it is live. The device must be installed in according to
EN61010 or EN62368-1. The device must have a suitable isolating facility
outside the power supply unit, via which can be switched to idle. Danger of fatal
Injury!
WARNING
– The device is equipped whit an internal fuse. If the internal fuse
blow Up (fails opens), it is most probable that there is a fault in the device. If this
failure occurs, the device must be returned to the factory.

How to Install
2.1 Dimensions
Fig. 1 – Dimensional drawing of the DPY351
2.2 Panel Mounting
Fig. 1 shows a dimensional drawing of the DPY351 .It is possible to mount the
DPY351 through a 90mm hole on the panel and fix it by 4 screws 2.9x16. There
is no limit for the Panel thickness. A mounting template at the end of this
instruction manual is provided.
Note: In conditions of extremely vibrations, mount the device on suitable anti-
vibration mounting.
2.3
How to Supply DPY351
The DPY351 can be powered from the ADELBus network. There must be an
ADELBus (AUX3) powering devices available to provide sufficient power to the
network. If there is no ADELBus powering device or the available power is not
sufficient, the DPY351 must be connected to a 12/24/48 V battery or Output
Load via the supplied connector (AUX5).

2.4.2
Ethernet Connection (AUX2)
"HUB" collector function of the connected devices to the ADELBus network, to
transport via Ethernet. The available protocols are the Modbus TCP/IP, the
SNMP protocol and the MQTTs. An internal password-protected HTTP server
allows to configure the network connection, to enable the network protocols, to
remotely control the DPY351 and to download the data log and event log.
2.4.3
PowerBus Connection (AUX3)
Automated RJ45 cable connection for Modbus and CANBUS protocols. The
Display must be powered via the AUX5 connector if the power provided from a
power device connected to AUX3 is not enough.
2.4.4
USB Connection (AUX4)
USB Connection for software updates via PC.
2.4.5
Auxiliary Input Power (AUX5)
Connect the positive wire to terminal 1, the negative wire to terminal 2 of the
connector a 3mm flat blade screw driver to push in the Spring Connect to supply
the DPY351 from a CBI Size3, it is necessary to connect the Output Load + and
– to Aux 5 since these devices cannot provide power through the AUX3
connector

2.4.6
Input / Output State Terminal 3,4,7,8 (AUX5)
The device is equipped with two digital inputs (terminal 3,4) suitable to reading
external conditions. They can be used for the most various
checks. For example: the control of opening doors, presence of protective earth,
verification of presence of Light, gas, pressure, etc...
The two inputs can accept any voltage between 0 and 70V with respect to the
DPY351 ground reference (AUX5, pin 2). Voltages lower than 3V are read as a
“0” or “logic-low” level; voltages higher than 7V are read as “1” or “logic-high”
level. A logic-high or logic-low level on either input can be configured to trigger
an alarm: to perform such configuration the
Menu > Display Configuration >
Advanced Configuration > Input/output > Input
menu page must be accessed.
It is then possible to configure, separately for each of the two inputs, which logic
level should trigger an alarm, if enabled, or no-alarm.
The Output relay (terminal 7,8) can be activated according to the state of the
inputs by means of an “Event” function or when the environmental temperature
measured by the sensor connected to AUX1 is higher or lower than user-
configurable alarm thresholds, or when any alarm is standing. The configuration
of the output relay behavior can be done at the page
Menu > Display
Configuration > Advanced Configuration > Input/Output > Output (relay),
where
it can be configured to be always open, always close, close when there is an
alarm on the inputs, close when there is an alarm on the environmental
temperature (or both), on alarms or on notifications.

How to connect the shunt in CBI Size 3
To display the load current on CBI “SIZE 3” it is necessary to add an external
shunt device, as explained in Fig.4. Consequently, it is possible to add this
parameter on the Dashboard or the monitoring panel. The supported shunt
ratings are 75mV/30A and 75mV/50A.
Fig. 4 – External Shunt connection for CBI Size 3
Shunt must be installed low-side in series between the Output Load - of the CBI
Size 3 and the “negative” of the load.
CAUTION
: NEVER install the shunt in series with the high-side of the load or
the battery! There is the risk of damaging the DPY351. Any damage resulting
from such wiring will void the warranty.
CAUTION: NEVER connect the CBI Load or battery outputs across the Shunt+
and Shunt- inputs of the DPY351! There is the risk of damaging the DPY351.
Any damage resulting from such wiring will void the warranty.
In order to get accurate measurements from the external shunt, the correct
shunt rating must be configured on the DPY351. This can be done in the
Menu
> Display Configuration > Advanced Configuration > Input/output > External
shunt sensor
menu. In the Sensor type page it is possible to select the shunt
rating. The setting done in this page must match the rating of the installed shunt.
In the Sensor calibration page it is possible to perform a one- or two-point
calibration to improve the measurement accuracy in the end-application. With a
single-point calibration only the zero-current calibration is performed. With a
two-point calibration both the offset and gain calibration is performed. In the
latter case the display prompts the user to specify the reference current provided
so that the DPY351 can compute the correct calibration constants. The Sensor
calibration is managed as a wizard that guides the user through the calibration
process. It is also possible to set a high-current alarm threshold. If such current
magnitude is exceeded, an alarm is triggered which, in turn, can be used to
activate the output relay, if its setting is “Close on alarm”.
2.4.8
Cabel Connections (AUX5)
Use appropriate wire size to connect the AUX5 power supply to the
battery. Fuse: Insert a 1A fuse in the positive battery line. For cable
size see Technical Data section.
