Connection diagrams
To install the relay correctly, you need to sierra leone email list 38886 contact leads decide on its connection diagram in advance. The choice depends on the configuration features and the main characteristics of the serviced electrical network, as well as other operating conditions.
The simplest option
To install a voltage relay in a single-phase network. The device is mounted immediately after the meter, thereby ensuring protection which ai writing tool is best for ecommerce content? of all consumers. This is the best option for residential premises (apartments, individual houses) where a small number of household appliances, electronic equipment and other equipment are used.
2. The voltage relay can also be installed in three-phase networks. This method is used mainly in industrial enterprises.
It is possible to install several
Voltage relays in a three-phase network at once. In this situation, a separate relay is connected to each phase. This option is used both in industrial calling list enterprises and in domestic conditions. This scheme is considered optimal in many cases, since it provides effective automatic control of each phase.
Step-by-step instructions for installation and connection Upper and lower
There are two ways to connect a voltage relay. In the first case, you need the help of a professional electrician who will perform all the necessary work, in the second case, you connect the device yourself. The self-installation option does not require much time and effort, since relay installation is classified as a simple electrical task.
Remember that the device must be installed only when the power is disconnected.
Before starting work, set the circuit breaker to the appropriate position
The next step is to mount the relay on a DIN rail. When the device is sold, a passport is issued with it, which lists the numbers of the input and output terminals. Install the relay so that its body is located as close as possible to the circuit breaker.
If the device is installed in a single-phase network, this must be done in accordance with the first diagram, the description of which is given in the previous section. If installation is to be done in a three-phase power grid, the second or third diagram must be used.
