6. Installation and Maintenance
Installation
- Installation Method: Usually base-mounted or DIN rail-mounted. During installation, ensure that the coil power supply is separated from the control circuit to avoid electromagnetic interference.
- Electrical Wiring: Power must be cut off before wiring to ensure that the control circuit is separated from the load circuit. Wiring shall be carried out in accordance with the wiring diagram or circuit diagram of GE products.
Maintenance
- Regular Inspection: Regularly check the contact wear, and clean or replace if necessary.
- Coil Replacement: Replace the coil in time if it is damaged to ensure the normal operation of the contactor.
- Fastening Inspection: Check whether the terminal screws are tight to avoid poor contact caused by looseness.
