Service environment
- Ambient air temperature: -5℃~+40℃ and the average temperature should not exceed +35℃ in 24h.
- Air condition: With clean air. Relative humidity should not exceed 50% at +40℃. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20℃. But in view of the temperature change, it is possible that moderate dews will produce casually.
- Altitude: Altitude above sea level should not exceed 2000M.
- Transportation & Storage: The device is suitable to the transportation and store with following temperature: -25℃ ~+55℃, in short time (within 24h) it reaches +70℃. Under the limiting temperature, device should not suffer damage that can’t recover, and it can works normally under normal conditions.
- If the above operating conditions not meet user’s demand, consult with manufactory.
- Technical agreement should be signed additionally if the device is used for marine petrol drill taken platform and nuclear power station.
Structure Characteristics
The basic cabinet of device is combined assembly structure. Basic structural pieces of cabinet is zinc plated, connected and firmed into basic bracket through self tapping locking screw or 8.8 grade square corner screw. According to the change demand of project, additionally add corresponding gate, closing board, baffle plate, installation support and the components of bus bar, function units, to assemble a complete set of device. Perform modulus to interior component and compartment size (Modulus unit e=25mm).
