6.1.1 控制柜开箱前应检查包装是否完好无损，开箱后应小心清除控制柜

6.1.1 Before unpacking the control cabinet, check whether the packaging is intact. After unpacking, carefully remove the sundries and dust on the control cabinet. <br>6.1.2 The following inspections must be carried out before installation. If it does not meet the requirements, it is not allowed to use. <br>a Whether there is an explosion-proof certificate number and an explosion-proof mark; <br>b Whether the model specifications meet the requirements of the equipped equipment; <br>c Whether all fastening bolts have been tightened, whether the spring washer is missing, and whether the connection between the components of the explosion-proof enclosure is proper. <br>d Whether the joystick and button lever are flexible. <br>e For control cabinets that have been transported over long distances or left unused for a long time, the insulation resistance value between the electrical components and the cabinet must be measured before use, and the value should not be less than 1.5MΩ, otherwise it should be dried. <br>6.2 Connection and adjustment <br>6.2.1 The wiring must correspond to the symbols marked in the control cabinet. <br>6.2.2 The outer diameter of the cable sheath through the sealing ring of the lead-in device should match the hole diameter of the sealing ring. After tightening the terminal bolts, the structure should be sealed, otherwise the explosion-proof performance will be lost. <br>6.2.3 The cable core wire should be placed between the two bow-shaped washers during wiring, and should be connected reliably to ensure good contact and meet the requirements of electrical clearance. <br>6.2.4 The internal and external grounding bolts should be reliably grounded.

6.1.1 Before the control cabinet is opened, check that the packaging is intact and carefully remove debris and dust from the control cabinet after opening the box.<br>6.1.2 The following checks must be carried out before installation and are not permitted if the requirements are not met.<br> a Is there a explosion-proof certificate number and explosion-proof signs;<br> b Whether the model specifications meet the equipment requirements for use;<br> c Whether all fastening bolts have been tightened, whether the spring washers are missing, and whether the connections between the components of the explosion-proof housing are appropriate.<br> d Flexible movement of the joystick and pushbar.<br>e After long-distance transportation or long-term shelving of the control cabinet, the insulation resistance between the electrical part and the case must be measured before use, the value should not be less than 1.5M, otherwise drying treatment.<br>6.2 Connections and adjustments.<br>6.2.1 The wiring must correspond to the markings in the control cabinet.<br>6.2.2 The outer diameter of the cable sheath by introducing the sealing ring of the device should match the aperture of the seal ring, and after tightening the joint bolts, the structure should be sealed or the explosion-proofing performance will be lost.<br>6.2.3 When wiring, the cable core should be placed between the two bow washers and should be reliably connected to ensure good contact and in accordance with electrical clearance requirements.<br>6.2.4 The inner and outer ground bolts should be reliably grounded.
