1. Preparation:
– Necessary protective equipment:
  • Safety helmets, protective gloves, safety shoes…
  • Warning board
– Necessary tools:
  • Water pressure pump
  • Electric tester
  • VOM meter
  • Flashlight
  • Traction pump, balang…
  • Device removal tool (Lock, hexagon…).
2. Maintenance of control cabinet system:
  • Before carrying out maintenance on industrial electrical cabinets, it is necessary to disconnect the power supply to the equipment. This step helps to ensure the safety of the maintenance engineer. As well as protecting electrical equipment in a state of rest when being serviced and replaced with new parts.
  • Check the Control and Protection Role. This inspection will be carried out from external observations to internal observations. Pay special attention to the screws and screws to see if they are tightened. Visible welds should also be tested for strength. After checking each part of the relay, it is necessary to adjust the relay coil to suit the operating ability of the industrial electrical cabinet.
  • Inspect and clean Aptomat and power tools. To check these devices, it is necessary to use screwdrivers, pliers, wrenches to tighten loose screws. It is necessary to measure and check the necessary electrical parameters before maintenance. The control circuits, automatic circuits of the device also need to be carefully checked. For non-electrical equipment, it can be cleaned with a clean rag or a special detergent. For electrical appliances, pay attention to cleaning only with a dry rag. During maintenance, try to completely remove all dust and dirt from the electrical cabinet.
