Flow box with wall mounted, can be installed on the wall, bracket or other support.

When the wall is installed or installed in the plane material thickness, can be in accordance with the size of the installation plane hole drilling, and then use the expansion screw or other ways to install the four attachment holes on the application of M6 screw tightening.

If installed on the bracket or where the plane material is thinner, you can get through the hole, and then use the bolt for a fixed installation.

3.3 electrical connection

Junction box of electrical wiring can be classified as string input wiring, output bus wiring, wire and network communication line four parts. All electrical wiring is located in the box at the bottom of the waterproof connector insertion to the inside of the box are connected, connection lock tight waterproof connector from the.

Line specification for 3.3.1

Before conducting the junction of the junction box, make sure to use the correct specification of the wire.

1 wire current carrying capacity is correct.

Control the junction box on the right side of the lower part of the wall plate, the input and output parameters of the search to the junction box. The rated input current 10A of the junction box, each input, please use not less than AWG13 specifications (or national standard 2.5mm) wire to connect; for the rated current for 20a of the junction box, each input to the use of not less than specifications AWG10 (or GB 6mm2) of wire. Similarly, output circuit of the wire to the rated current of the reference junction box input channels and each channel. Specific line specifications can refer to the relevant electrical standards.

2 the diameter of the wire is suitable.

Waterproof connector locking range is limited, we must use the appropriate size of the square wire can ensure the reliable locking will not be waterproof. Our company junction box products in the design fully consider the connection, according to the input output current specifications general wire diameter size is calculated and choosing appropriate range lock tight jacket.CF series junction box used waterproof connector locking range is as follows:

Note: please be sure to confirm that the outer diameter of the junction box is in the locking range of the above table. Using the wire outside the above range will cause the cable to be unable to pass through the waterproof connector or the waterproof connector can not be locked tightly.

3 selection of communication lines.

485 communication line, be sure to choose standard STP, recommended line diameter not less than 1.0mm -.

3.3.2 group input connection

Recommend the use of crimping terminal, will be peeling wire head pressure connected access fuse or terminals, to ensure the connection reliability.

The sequence of the sequence of the group should be noticed, from left to right in order to loop 1, loop 2...... Loop 16, and positive and negative to the corresponding, or may result in the display of the group is not allowed to monitor the current series of positive wire connection as shown in Figure 3.2 below.

The 3.2 group of positive electrode wire is connected to the positive electrode.

A series of negative terminals are connected to the negative input fuse or the negative input terminal.

Connection of 3.3.3 bus line and ground wire

The output of the junction box is connected to the output terminal or the output circuit breaker.

3.3.4 networking communication line connection

The wiring of network communication line is shown in Figure 7

Fig. 3.6485 schematic diagram of network communication line

Be careful：

1.485 the positive and negative polarity of the communication line must be correct, otherwise it will lead to unable to communicate.

Be sure to use the standard 2.485 line shielded twisted pair wire diameter not less than 1mm. And with the strong electric field - Part separate the line.

3.485 communication theoretical distance can reach 1000 meters. But based on the actual conditions of the site restrictions, it is recommended that the communication distance should not exceed 100 meters.
