Environment
- Ambient temperature: Shall not exceed +40℃ or be lower than -5℃, with a 24-hour average not exceeding +35℃. If exceeded, the operation capacity shall be reduced according to the actual situation.
- Location and altitude: For indoor use, with the altitude of the installation site not exceeding 2000m.
- Relative humidity: Shall not exceed 50% at a maximum temperature of +40℃; higher relative humidity is allowed at lower temperatures (e.g., 90% at +20℃), with consideration that condensation may occur occasionally due to temperature changes.
- Installation conditions: The tilt with the vertical plane during installation shall not exceed 5%, and the mounting surface of the cabinet shall be relatively flat.
- Site requirements: The device shall be installed in a location without severe vibration and impact, and where electrical components are not susceptible to corrosion.
- Special requirements: Users with special requirements can negotiate with the manufacturer for a solution.
