The left and right mounting brackets of the change over switch must be fixed on the same flat plane. The size of the mounting hole should be adjusted according to the actual situation. It is strictly prohibited to use the wrong size of the opening to forcibly install the switch, which will lead to the internal deformation of the switch, or even direct damage to the switch. 2. It is recommended to use busbar for the installation of switches above 2000A. If the cable installation will increase the stress of the installation bracket, please add effective reinforcement measures.3. Vibration and gas: in its use environment, there should be no strong vibration or impact, nor should there be harmful gases that corrode metals and damage insulation materials.4. Surrounding materials: no serious dust, conductive particles or explosive hazardous substances.
