Installation and maintenance
Installation suggestions:
Install vertically in a well-ventilated control cabinet to avoid contact with corrosive gases.
The control cable is wired separately,and the shielding layer is grounded with a single end.
Maintenance cycle:
Check the contact oxidation every six months and replace the arc extinguishing cover if necessary.
The coil resistance is detected every year,and it is recommended to use a Fluke 7.74 multimeter.
Troubleshooting:
If the contactor cannot be absorbed,priority is given to check whether the control voltage is stable(24V±10%).
In high humidity environments,dry air needs to be used to purge the internal coil regularly.
