How to wire the bay gas fire extinguisher connected to the power box

The power switch can be classified into two categories, one is two-wire, the other is three-wire, but the two-wire power switch and the three-wire power switch are not big, only one more ground wire, and the ground wire is also no voltage, but there is one more protection function for the power supply, to prevent the power switch from burning out due to excessive power. In addition, whether it is a three-wire or a two-wire connected wire, there must be a neutral wire and a live wire, and the only wire with more is the ground wire. The abbreviations of the neutral wire and the live wire are L and N respectively, which are 220V alternating current, and the abbreviation of the ground wire is FG, which is directly connected to the earth and has no voltage.

How to connect the power switch - the link method of the two-wire power supply.

The two-wire power switch is aimed at low-power appliances, such as electric lights. Small electrical appliances do not have a high demand for voltage, so the voltage requirements for the power switch are not large, and the two-wire power switch can be controlled. The two wires connected to the neutral wire and the live wire, generally there is no clear link order, can be confused, but can not let the two wires have some contact, that is, it is worth noting that to ensure that the wire is connected, the problem of anti-electric protection, do not let the wire expose the outer skin or power switch.

How to connect the power switch - the link method of the three-wire power supply.

The role of the three-wire power switch is much better than that of the two-wire power switch, and it can support the use of many high-power electrical appliances, such as refrigerators, air conditioners and other electrical appliances. The three-wire power switch can be seen from the name, and it is controlled by three wires, neutral wire, live wire, and ground wire. It should be noted that the ground wire can only be connected to the top place, and there is an independent mark, and it cannot be connected wrongly.

In addition, the neutral wire and live wire can be confused in the order, but the two wires should not be contacted, and it is necessary to pay attention to the anti-electric protection, and do not let the wire expose the outside of the foreskin or power switch.

To sum up, it is the topic of how to connect the power switch prepared for you today, I hope it will help you in daily life, in addition, warm reminder, you must pay attention to the power off in advance when connecting the power switch, the safety voltage of the human body is 36V, our household 220V, if you are electrocuted, it will damage the human body.

Use a network card and connect it by cable.

There are a lot of fire-fighting equipment in the bay, I don't know which model of equipment you are talking about. Send you a design manual, you can refer to it.
