Applicability
The ATEX evaluation and the special conditions in this section apply to part numbers:
50001825-03
50001825-06
WARNING! Digi Connect Tank is suitable for use in ATEX Zone 2, Group IIA hazardous locations or
non-hazardous locations only.
WARNING! The Digi Connect Tank unit should be installed only in process tanks containing
neither non-pressurized nor non-flammable materials. The battery should be
replaced in unclassified areas only.
WARNING! The Digi Connect Tank is intended for fixed installation, where the installation is
intended to minimize the risk from electrostatic discharge. Instructions are provided
for guidance for the user to minimize the risk from electrostatic discharge.
WARNING! Install the Digi Connect Tank in an area that does not have more than pollution
degree 2 as defined in EN/ IEC 60664-1.
WARNING! To avoid potentially dangerous static discharges, control all likely ignition sources,
minimize the harmful effects of any accidental fire or explosion by using explosion
relief and suppression systems. All zoned areas containing potentially explosive
atmospheres should be clearly marked using ATEX Ex hazardous area warning signs.
ATEX product marking
The device must be marked with the CE Mark, the ATEX logo and the ATEX classification below:
II 3 G Ex nA IIA T6 Gc IP54

Digi Connect Tank, special conditions for safe use - (ATEX)
Digi Connect Tank Getting Started Guide 10
Explanation of the ATEX product marking
The following table provides the meaning of the ATEX marking.
Mark Meaning
The ATEX symbol. This symbol indicates certification for use in an explosive
atmosphere. The symbols that follow it provide the details of that certified use.
II This indicates Group II (Clause 4.2). The equipment is intended for use in places with
an explosive gas atmosphere other than mines susceptible to firedamp.
3This indicates Equipment category 3. Category 3 comprises products designed to be
capable of keeping within its operational parameters, stated by the manufacturer,
and based upon a normal level of protection for its intended use, considering areas
in which explosive atmospheres caused by mixtures of air and gases, vapors, mists
or air/dust mixtures are unlikely to occur and if they do occur, do so infrequently and
for a short period of time only.
GThis indicates the Environment based on International Electrotechnical Commission
(IEC) 60079-0, Clause 29.4.
Ex This indicates Ex Components.
nA This indicates that the device is non-sparking (Gc).
IIA This is the Group symbol where IIA is for electrical equipment for places with an
explosive gas atmosphere other than mines susceptible to firedamp.
T6 This is the Temp Code, indicating a maximum surface temperature of 85°C.
Gc This indicates the Equipment Protection Level. Gc means equipment for explosive
gas atmospheres, having an “enhanced” level of protection, which is not a source of
ignition in normal operation and which may have some additional protection to
ensure that it remains inactive as an ignition source in the case of regular expected
occurrences (for example failure of a lamp).
IP54 This indicates the Ingress Protection (IP) rating. Optional.

Assemble Digi Connect Tank
Required tools
To assemble the Digi Connect Tank, you need one 9/64" hex (or Allen) wrench.
Assembly instructions
Digi Connect Tank assembly consists of these basic steps:
1Insert the SIM Card. You must install an activated SIM. The SIM card holder is installed on all
models except CDMA models.
2Connect the battery. See the Digi Connect Tank Quick Start Guide for detailed installation
instructions.
3Register the device on a network. See Register Digi Connect Tank on a cellular network on
page 19 for detailed instructions.
4Upload the device information to Device Cloud. See Register Digi Connect Tank with Device
Cloud on page 20 for detailed instructions.
5Mount the Digi Connect Tank.
CAUTION! Mounting the device vertically ensures proper orientation. If the device is not
mounted vertically, the device may send erroneous readings. Cover screws are
required as part of the safety rating.
Ensure good network coverage for cellular and GPS
antennas
Digi Connect Tank has internal antennas for cellular and GPS communications. There are no
external antennas required to operate the device. While installing the device, make sure that
there is adequate network coverage in the area by ensuring that the cellular LED is blinking blue.
Good network coverage helps reduce power consumption, leading to improved battery life.
Unauthorized antenna modifications and attachments invalidate the device type specifications
and may violate local RF emission regulations.
Wake up Connect Tank
You can wake up Connect Tank using the Wake-up button or the magnet provided with Connect
Tank. When you press the Wake-up button or activate the magnetic switch, the device performs
the following functions.
• Sends a diagnostic record to Device Cloud with the following device information:
• Sensor connect status
• Measured distance reading
• Measured temperature reading
• GPS location (optional, based on configuration)

Wake up Connect Tank
Digi Connect Tank Getting Started Guide 18
• Battery voltage (the current battery percentage remaining)
• Device configurations
• Cellular signal strength
• Battery and network status LEDs glow indicating their respective functions. See Digi Connect
Tank status LEDs on page 40 for more information on the system status LED sequence.
Wake up Connect Tank using the wake-up button
If the Connect Tank enclosure is open, press the Wake-up button to wake up Connect Tank.
Wake up Connect Tank using the magnet
Note This was not evaluated as part of the ATEX evaluation.
If the Connect Tank enclosure is closed, use the magnetic sensor to wake up the device. To wake
up Connect Tank using the magnet:
1Bring the magnet close to the magnet icon on the Digi Connect Tank.
After several seconds, the LEDs start blinking indicating that the device is up and running. See
Digi Connect Tank status LEDs on page 40 for more information on the system status LED
sequence.
Note Waking up the device using the magnet is the same as pressing the Wake-up button.
2After wake-up, Digi Connect Tank sends the device configuration settings and data to Device
Cloud. After sending all configuration settings and data to Device Cloud, the device enters
sleep mode. The device remains in sleep mode until the next scheduled or manual wake-up.
Configure wake-up for data acquisition and reporting
Using configuration options, you can configure Connect Tank to wake up to perform the following
functions:
• Monitor the tank liquid level
• Report data to Device Cloud
• Check for a new configuration file from Device Cloud
