Safety Chapter
DLT-V72 Series User Manual V2.70
16 / 173
2.1. Please read and observe.
These safety instructions apply to all device models in the DLT-V72 Series: For DLT-
V7210 and DLT-V7212 in various equipment levels.
WARNING Non-observance of the safety instructions can result in injury to
persons and in physical damage, e.g. due to incorrect
commissioning procedures or due to maintenance work not
being completed. The manufacturer accepts no liability for
damage resulting from a failure to comply with this information.
1. Read and observe these safety instructions before
commissioning and using the DLT-V72. This protects you and
other persons and prevents damage to the equipment and to
technical equipment in the surrounding environment.
2.2. Requirements for commissioning and operating
personnel
Work such as commissioning and maintaining the DLT-V72 is only permitted to be
performed by skilled personnel who have specialist vocational training and who have up-
to-date knowledge and experience in the area of work in question.
Examples:
Mechanical mounting work must be performed by skilled mechanical personnel.
If the DLT-V72 is incorrectly mounted onto vehicles, for example, this can result
in serious accidents.
Electronic work on the DLT-V72 must be performed by skilled electronics
personnel; there is a risk of electric shock when connecting to the power supply,
for example.
For the DLT-V72 with integrated UPS, specialist knowledge on the handling of
battery packs is required.
Requirements for the operating personnel
Users of the DLT-V72 must be trained by skilled personnel and instructed in the
operation of the device. All users must be familiar with all functions of the product they
come into contact with.

Safety Chapter
DLT-V72 Series User Manual V2.70

2.3. Battery pack safety
The DLT-V72 is optionally available with an integrated UPS. The battery pack of the UPS
is located in the battery pocket of the device:
Fig. 2.1: Battery pocket with UPS DLT-V72
EXPLOSION HAZARD! BATTERY PACK SAFETY NOTICE
Battery packs may ignite if stored or handled incorrectly (fire risk, explosion risk), and
may cause chemical burns or release poisonous substances.
1. Handle the DLT-V72 and the integrated battery pack with care, and do not
allow it to become damaged, to fall or be dropped, or be short-circuited.
2. Do not tamper with, disassemble or repair the battery packs.
3. Observe the specified temperature range, both during storage and in the
work environment.
4. Do not utilize the device near sources of heat or fire, open flames or
heaters.
5. Do not allow water or other liquids to come into contact with the device
(exercise particular caution with corrosive liquids).
6. Suitable fire extinguishers must be provided in line with safety regulations.
7. If battery packs become damaged, caustic electrolyte liquid may leak out.
This liquid must not under any circumstances be permitted to come into
contact with eyes, skin or clothing. On contact with eyes or skin, rinse
immediately with clear, running water and consult a doctor.
THERE IS A RISK OF EXPLOSION IF THE BATTERY PACK IS SWAPPED OUT
AND REPLACED WITH AN INCORRECT/NON-APPROVED BATTERY PACK.
This also applies to the real time clock battery installed in the DLT-V72.
Do not open the DLT-V72, and do not replace the RTC battery.
No third-party battery packs permitted.
1. Use only original battery packs from Advantech. If battery packs from other
manufacturers are inserted in the DLT-V72, the warranty for this device will
be rendered void.
2. The battery packs must be certified for the DLT-V72.
3. Do not use battery packs from any other Advantech devices; they are not
compatible.

Safety Chapter
DLT-V72 Series User Manual V2.70
18 / 173
Prevent physical damage due to deep discharge.
Storing the battery packs incorrectly will cause them to discharge completely (deep
discharge) and thus damage them irreparably.
To prevent a deep discharge:
1. Remove the battery pack from the battery pocket, if the DLT-V72 is not
used for a longer period of time (more than one month).
2. Charge the battery pack in the DLT-V72 device every six months.
2.4. HF Radiation
Only applies to devices with radio equipment: Danger of radiation.
DLT-V72 devices with radio equipment emit high frequency energy (abbreviation: HF).
To protect persons and domestic animals against HF radiation:
1. Mount the DLT-V72 so that persons and domestic animals maintain a
minimum distance of 20 to 50 cm from the radio antennas.
2. Ensure that persons observe this minimum distance when operating the
DLT-V72.
3. High frequency energy can interfere with technical devices. For this reason,
do not use the DLT-V72 in the vicinity of pacemakers or other medical
devices.
4. Only operate the DLT-V72 with radio equipment that is approved by the
manufacturer for this device.
5. Make sure that the transmission power and the radio frequency of the DLT-
V72 comply with the regulations for the respective country where the
device is deployed.
6. Observe all applicable regulations for your deployment location/country
with regard to operating channels, radio frequencies and the maximum
permissible transmitting power. Responsibility for this lies with the company
operating the DLT-V72. The regulatory authorities in the relevant country
can provide information on this.
Any modifications to the DLT-V72 radio equipment which are not expressly approved by
the party responsible for the compliance can lead to the withdrawal of the operating
license for this device.

2.5. Information on safe mounting
During the mounting process
The DLT-V72 can fall down and cause injuries due to its weight.
1. Use the assistance of a second person for installation work.
2. Always hold the DLT-V72 by the housing with both hands.
3. Never use the antenna cap as a handle as it may break due to the weight
involved.
The strain relief rail of the DLT-V72 can have sharp edges and cause cutting injuries.
1. Do not hold the DLT-V72 by the strain relief rail.
Choosing the mounting position and installation environment
The installation height of the device shall not exceed 2 m.
1. The ergonomic operability of the DLT-V72 should be taken into account
when selecting the mounting position.
2. Mount the DLT-V72 in such a way that no persons can be injured if the
device mounting should break (e.g. as a result of a fatigue fracture).
3. Otherwise, it is essential to adopt corresponding safety measures.
4. Ensure that the installation environment is correct, as is not permitted to
result in an enclosed system because the cooling concept of the DLT-V72
requires fresh air. Without a supply of fresh cooling air, the DLT-V72 may
overheat and may be damaged beyond repair.
Specific information on vehicle mounting (forklifts, etc.)
1. Mount the DLT-V72 so that the driver's field of view remains clear and safe
driving operation is guaranteed.
2. During the mounting process, observe the requirements of the vehicle
manufacturer relating to attaching auxiliary devices and connecting
auxiliary consumers.
3. Observe all requirements relating to welding or drilling on support
components of the vehicle.

2.6. Information on safe electrical installation
Danger of electric shock
1. Do not put the DLT-V72 into operation if it is showing damage.
2. Do not open or modify the DLT-V72.
3. Only connect or disconnect electrical connections when the device is in a
de-energized state.
4. Use only original Advantech power supply cables; these meet the specific
requirements for low-temperature flexibility, UV resistance, oil resistance,
etc.
Installing the disconnecting device
The DLT-V72 is not equipped with disconnecting devices that are accessible from the
outside; it does not have switches.
1. To allow the device to be quickly disconnected from the power supply in
emergency situations, install an easily accessible disconnecting device
close to the device and ensure that the disconnecting device isolates all
supply lines.
Fuses
2. Only connect DLT-V72 devices to Safety Extra Low Voltage (SELV)
circuits.
3. The DC+ connecting cable must be protected by a fuse (30 AT max.).
4. The ignition connecting cable must be protected by a fuse of the following
type:
5x20 mm T 125 mA L / 250 V, for example, a Wickmann 195-125 mA / 250
V.
Power supply unit fuse blows repeatedly
If the fuse of the integrated power supply unit blows again immediately after replacement,
proceed as follows:
1. Check the electrical installation.
2. If it’s excluded that a faulty installation causes the problem: Send in the
DLT-V72 immediately for repair.
