# Device use, cleaning and routine care Canonical source: https://sotengroup.com/resource/maintenance-en/ Language: en Publisher: SOTEN GROUP Manage batteries, ports and accessories according to model documentation and field conditions. Project preparation and validation workflow ## Use the correct documentation Confirm model and configuration and review operation, charging, accessories and environmental limits. Protection ratings do not imply equal protection in every port state. ## Batteries and charging Use approved batteries and chargers, keep connectors clean and dry and follow temperature requirements. Stop using damaged, swollen or abnormally hot batteries and contact support. ## Cleaning and sealing Follow device cleaning instructions and inspect covers, seals, enclosure and mounts. Avoid unapproved chemicals, high-pressure cleaning or disassembly. ## Accessories and spares Maintain mounts, harnesses, docks and connectors. Match spares to the device revision and retest connectivity, power, sealing and workflows after replacement. ## Hazardous-location devices For hazardous-location devices, follow approved battery, accessory, charging and maintenance documentation rather than general-terminal procedures.
