3. Flameproof enclosure with indicator light, ammeter, voltmeter, button, digital display meter, relay, etc;

4. The built-in components can be arranged, installed and produced according to user requirements;

5. Steel pipe or cable wiring.

5、 Installation and repair:

1. Before installing the control box, check whether the technical parameters of the distribution box are consistent with the application conditions.

2. The control box shall be firmly grounded.

3. When installing the device, ensure that the wiring is firm and firm to prevent overheating or sparks due to poor contact during operation.

4. No matter what wiring method is selected, it is necessary to connect the cable to the wiring terminal through the sealing ring. After connecting the wire, press the sealing ring to ensure the explosion-proof function.

5. The distribution box shall be protected and overhauled regularly. During installation and repair, "live cover opening is prohibited!".

6. The electrical clearance and creepage interval in the wiring cavity shall be ensured.

7. If the sealing ring (gasket) is found to be aging during repair, contact our company in time and order replacement to ensure explosion-proof function.
