Firstly, the explosion-proof cover comes in two types: high cover and low cover. We generally use the low cover, but for AC voltages above 40A, a high cover is required. If a circuit breaker is used nearby, the corresponding shaft is also needed. The EZD/4p circuit breaker must have the high cover. Customers also provide parts and offer corresponding convex and concave covers based on the actual situation.
Next, explosion-proof room: The wires connected to the explosion-proof room must pass through transition nuts. The washer at the transition nut is crucial. Open the washer according to the diameter and quantity of the wire. The wire diameter should match the hole size. Then, press the washer into the transition nut, ensuring it is flat. During the pouring process, pay special attention to any leaks in the washer. Check the edges to prevent damage; the components and packaging should be even, without bubbles.

Additionally, generally speaking, the components used in explosion-proof refrigerators must be housed within an explosion-proof room to prevent leakage and contact with hazardous substances in the workplace, thereby achieving the purpose of national safety and technical production. Production Note: Firstly, place the guide plate inside the explosion-proof room, ensuring the direction is correct. The circuit breaker should be adhered to the track, followed by aligning the mechanical equipment with the holes on the cover plate. Pay attention to the small details on the explosion-proof shaft: there is a black small buckle on the shaft that needs to be clamped, fixed, and tightened. The fixed position is flexible in operation, with clear disassembly directions. After the handle is locked in place, adjustments to the handle's position must be made from the beginning.
