First of all, according to the use of electrical components to choose the use of different components are different, mainly because the different components and components, mainly because the engineers need to design!
Generally more commonly used are isolated switch circuit breaker contactor relay fuse thermal relay transformer voltage ammeter signal light button terminal block and so on it a lot.
         1, sheet metal inspection and painting, screen printing 1) equipment sheet metal arrived in the workshop, the electrical assembly staff should take the drawings to check all the electrical cabinet, electrical floor, electrical panels, button boxes and electrical accessories Is the size correct? Is the electrical alignment hole on the bed of the equipment missing? Are all the mounting holes correct?
2) sheet metal inspection is correct, the electrical assembly staff to the workshop director to explain, immediately sent to paint or spray.
3) paint or spray to get back the electrical panel, such as the need for screen printing, need to immediately sent to screen printing.
         2, to find the electrical equipment needed for the installation of equipment 1) electrical assembly personnel must first find the equipment used to have been sprayed on the electrical cabinet, electrical floor, electrical panels, button boxes and electrical accessories.
2) Electrical assembly personnel to prepare their own tool kits (including large, medium cross, small word, stripping pliers, diagonal pliers, electrical waterproof tape, multimeter, hex wrench, stay wrench, Φ2.5 Drum, Φ3.2 Drill, Φ4.2 Drill, M3 Taps, M4 Taps, Taps, Wrenches, Rough Set, M3 Screws, M4 Screws, M4 Nuts, Hand Drills, Place all tools neatly on an arm In the range.
         3, the installation of electrical floor 1) according to the electrical schematic diagram of the layout of the floor plate and the length of the track, with a saw cut off. (Note: the trunnion should be placed in a flat place saw, the guide rail to be caught in the tiger clamp saw, saw the seam to be straight.) 2) after the saw can be straight grinding machine. If two trunks are seated together, one end of one of the trunking should be ground at an angle of 45 degrees.
3) hand drill in the slot, guide the two ends of the fixed hole (with Φ4.2 drill).
4) Place the trunking and guide rails on the electrical floor according to the layout of the electrical floor, and use the black marker to draw the position of the positioning hole on the electrical floor.
5) first in the electrical floor with a kind of punch-like eye-catching, and then hand drill drill hole in the eye (with Φ4.2 drill).
6) with M4 screws, nuts will be trough, rail fixed on the electrical floor.
7) switching power supply, printed circuit boards and other non-removable electrical components are to be perforated, the wire (with Φ2.5 drill hole, and then with the M3 tap wire), printed circuit board below to pad Copper pillars (M3 × 20).
8) Servo control drive, inverter to use Φ3.2 drill hole, and then use the M4 tap wire.
9) General electrical components are under a slot, is dedicated to stuck in the C-type rails, the Phoenix terminal is generally stuck in the C-type rails, and other terminals generally use high and low rails.
         4, wiring 1) three-phase circuit generally use 2.5 square wire connection, the control circuit to control the motor's main circuit and electrical cabinet connected to the external line with 0.75 square wire connection, the other lines are generally used 0.5 square wire.
2) signal sensors, instrumentation communications, computer communications, analog board input, oscilloscope input signal lines are connected with shielded cable.
3) wire strippers generally stripping length of 5 ~ 7 mm, should not be stripped too long, but can not use the diagonal pliers stripping, easy to damage the wire.
4) Relays, air switches and other common components to use forked handle, Phoenix terminal, Siemens plc terminal and other small diameter terminal to use the needle handle, the middle of the two wires to use the middle of the transition wiring.
5) All the wires on the ground to wear plastic hose, exposed to the outside line to wear black bellows, electrical lines along the suction plate, and then tied with nylon tape on the sucker.
