China Low Voltage Switchgear Work Environment 1.Ambient air temperature: -5鈩儈+40鈩?and the average temperature should not exceed +35鈩?in 24h 2.Indoor altitude above sea level: Maximum installation altitude: 2000m 3.Relative humidity should not exceed 50% at max temperature +40鈩? Higher relative humidity is allowed at lower temperature. Ex. 90% at +20鈩? But in view of the temperature change, it is possible that moderate dews will produce casually. 4.No fire, explosion danger, serious pollution, chemical corrosion and severe vibration 5.Installation gradient not exceed 5掳 6.The equipment shall be installed in a place where there is no violent vibration and impact, and the place where the electrical components are not corroded. 7.Any specific requirement, consult with manufacture Product integrity 1. Device list; 2. Product qualification certificate; 3. Instruction manual; 4. Factory test report; 5. Relevant electrical drawings; 6. Door key, operating handle and contract requires for spare parts; 7.
