Installation and Maintenance
Installation Preparations:
Before installing the Emax 2, verify the ambient temperature (-40°C to +70°C standard) and mounting surface stability. Ensure the power supply matches the breaker’s rated voltage (400V AC or 690V AC) and use torque wrenches to secure busbar connections (tightening torque: 25–50 N·m, depending on model). For withdrawable units, test the racking mechanism for smooth operation.
