Special safety requirements
1. WARNING – DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT
2. WARNING – DO NOT CHARGE THE BATTERY IN HAZARDOUS LOCATION
3. WARNING – USE ONLY the approved batteries, see Ex instruction
4. The equipment needs to be protected from high impact energy (do not drop or hit the unit)
5. Do not touch the non-metallic enclosure or touch with the insulating materials only
6. The batteries used in the equipment with same manufacturer, same models and same electrochemical system
7. The conformal coating applied to PCB boards meets the requirements of IEC 60664-1 and IEC 60664-3 by the
manufacturer
8. Operating temperature: -20
℃
to +50
℃
.
9. USB port only to be used in Non-hazardous areas.
10. The lemo type ports can connect with ADT161Ex pressure modules only, the connected cables and flexible hose
used for the external pressure modules are made of insulation materials, so end user should consider the risk of
electrostatic discharge during material selection and installation process
11. Metallic parts (only fasteners) presented a maximum capacitance of total 110pF, end user should consider this risk
for suitable application
12. No additional input energy limitation is required for Type-C USB port and DC charging port when Um does not
exceed 250V (internal OVP/OCP are designed in line with IEC 60079-11)
