Indicator wiring method for industrial water heaters
The solenoid valve of the water heater has three wires: first, peel off the three wires on the plug-in board by about one centimeter. Open the connection cover of the leakage protection plug, the terminal is under the plug, exposing three terminals, the middle hole is the ground hole, the ground wire. The holes on both sides are connected to the fire line and the zero line.
The connection method of the water boiled indicator thermostat AC contactor is as follows: the power supply enters the main contact of the contactor, the exit contact is connected with the heating tube of the water heater, and one end of the thermostat is connected with a phase fire wire. Feel the temperature inside the refrigerator through the end of the capillary and change to the corresponding pressure.
First, prepare a screwdriver and remove the screws from the shell. Secondly, open the shell and put the control circuit of the lamp on the control board. Then connect the hot wires of the three wires with the corresponding L connection posts. Finally, the zero line should be connected with the N terminal.
How do I get the lights?
1. The connection method of the lighting switch is as follows: first, turn off the total power, single connection: the power cord is connected with the L port on the back, and the hot wire of the lamp is connected with L1. Duplex: the power cord is connected to the L end, and the fire wires of the two lamps are respectively connected to the other two ends.
2. First, install the current limiting resistor on the negative pole of the power cord. Then separate the positive and negative lines of the LED lamp strip. Use a stripper to remove the positive wire of the LED lamp belt. Stripped positive line of LED lamp. Connect the negative wire of the power supply with the positive wire of the LED lamp strip.
3. The following are the switches of three terminals: l connection line (red line), L1 (blue line) to one end of the first lighting, and L2 (blue) to the second lighting.
4. The connection method of the household electric light switch: pass the zero line directly through the lamp holder, and then place the line on the central point of the switch. Connect the two sides of the light switch with a wire. When going out, one is connected to the center point of 220v and the other is connected to the switch.
5. How to connect the led lamp into the wire at both ends: this is one of the more common connection methods in the early days. Because of the advantages of convenient wiring and other advantages, there are still some LED lamp manufacturers. Connect the two needles of the lamp holder short, and then connect them to the internal constant current power supply. This connection method can work normally as long as the traditional starter is removed.
6. Triangle connection can be used. Take any combination of phase line and zero line to get a single-phase power supply, and the light bulb can be connected to the hot wire and zero line of the single-phase power supply. The triangle connection method is to connect each phase power supply or load end to end, and draw out each connected point as the three phase lines of three-phase electricity.
How to connect the light switch
1. The connection method of the lighting switch is as follows: first, turn off the total power, single connection: the power cord is connected with the L port on the back, and the hot wire of the lamp is connected with L1. Duplex: the power cord is connected to the L end, and the fire wires of the two lamps are respectively connected to the other two ends.
2. Most of the wiring methods are L or L1 connection. Let’s look at the wiring of the two types of switches. L connection line (red line), L1 (blue line) to one end of the first light, L2 (blue) to one end of the second light.
3. The connection method of the lighting switch is as follows: first, connect the hot wire and zero wire of the power cord to the switch. Usually, the switch has two connectors, one is L, the other is NMagel L for hot wire, and N represents zero wire.
4. The connection method of the household electric light switch: pass the zero line directly through the lamp holder, and then place the line on the central point of the switch. Connect the two sides of the light switch with a wire. When going out, one is connected to the center point of 220v and the other is connected to the switch.
5. The connection of the single-connection switch is the simplest, and there are only two terminals on the back of the switch. It is generally marked “L” and “L1”. We need to connect the power supply to the end of the LMagol L1 light. A duplex switch has something in common with a single switch, except that a set of buttons and terminals are added. The double switch can be divided into three terminals and four terminals.
6. Disconnect the power supply, pull down the main brake of the electric box and cut off the power. Remove the original lamp port wiring and remove the lamp port. Connect the fire wire of the original lamp to the fire wire of the remote control switch (usually red), and the power supply zero line of the original lamp to the zero line of the remote control switch (usually black wire).
