The installation and use of the general principle of low-voltage electrical appliances:
1, low voltage electrical appliances should be installed vertically. Especially for oil immersed starter. In order to prevent the insulating oil overflow tank inclined shall not exceed 5 should use the bolt is fixed on the support and should not be used welding: the installation position should be easy to operate, and between the handle and the surrounding buildings to maintain a certain distance. Not easy to be broken.
2, low voltage electrical appliances should be installed from the ground in the absence of violent vibration of the place to have the proper height. Knife switch, load switch power supply line must be connected with the fixed contact. Is strictly prohibited in the knife switch hanging power lines.
Metal or metal bracket 3, low-voltage electrical appliances must be grounded (or zero). The exposed part of an appliance shall be added to the shield double throw knife switch off position should prevent self closing device.
4, in the flammable and explosive gas or dust workshop, the appliance shall seal installed outdoors, and the rainproof measures, the use of explosion-proof electrical apparatus for explosive places must be.
5, use should be guaranteed to be in electrical contact surface clean, smooth, good contact, contact with sufficient pressure, the contact action should be consistent, arc extinguishing device should be kept intact.
6, should be removed before use reservoir protection of each of the contact surface on the investment operation before the operation several times, check operation. The static contact should be the power of low voltage electrical apparatus, a moving contact connected load.
7, a single pole switch to be connected to the line. Low voltage electrical installation of landing. The bottom should be 100mm above ground in the installation of low-voltage electrical equipment installation disk, indicate the name and serial number of loop or road don't.
