Installation and maintenance
Installation suggestions:
Install vertically in the metal cabinet,leaving≥100mm of heat dissipation space.
The busbar connection requires a copper bar(sectional area≥120mm²)and a tightening torque of 120N·m.
Maintenance cycle:
Check the contact wear amount every quarter(standard:single-sided wear≤1mm),and replace it after exceeding the limit.
Test insulation resistance every year(required≥500MΩ).
Troubleshooting:
If the opening is abnormal,the stretching amount of the energy storage spring is checked first(standard:150±5mm).
In high humidity environment,the insulation resistance of the opening and closing coil needs to be detected(required≥100MΩ).
