Explosion-proof lighting switch installation should meet the following requirements.
1 Switches installed in the same building or structure should adopt the same series of products. The on-off position of the switch should be consistent, and the operation is flexible and reliable.
2 switch installation location should be easy to operate, switch edge from the door frame distance should be 150 ~ 200mm; pull handle switch from the ground should be 1.2 ~ 1.4m, wiring switch should be 2.2 ~ 2.8m from the ground, and the cable outlet should be vertical Next, it is not easy to pull the cable.
3 The same type of parallel installation switch distance from the ground should be the same, the height difference should not be greater than 1mm; switch height difference of the same indoor installation should not be greater than 5mm; the adjacent spacing of the parallel installation switch should not be less than 20mm.
4 The unipolar switch should be placed in the phase circuit instead of in the neutral circuit, which is beneficial to the safety when overhauling or cleaning the luminaire.
5 The switch must be securely mounted. It must not be fixed with only one screw.
6 Do not install switches in dusty, damp rooms such as kitchens and bathrooms. When installing, be sure to use moisture-proof and waterproof switches. Outdoor site switch, apply waterproof switch.
7 The surface mounted switch shall be installed on a wooden platform with a thickness of 15mm; the concealed switch shall be assembled with the panel, junction box, and adjustment plate (if any), and the panel shall be installed with a positive, tight, and flush with the wall. .
8 The wires of the same color should be used for the incoming and outgoing wires of the switch.
9 The end of the wire shall be pressed tightly into the terminal and there shall be no exposed wire on the outside.
10 There should be a certain margin in the wire inside the switch box.
