CI810B 3BSE020520R1 ABB Bus communication interface control power board card is available for after-sales

Description

CI810B 3BSE020520R1 has two kinds of adapter brackets for installing the 10 slot series 90-30 base plate to the 19 inch rack. No matter which adapter bracket is used
Rack and 19 inch rack shall be grounded according to the “System Grounding Procedure” and Figure 2-10. (ABOUT ADAPTER BRACKET
For details, refer to the section “Installing the Base Plate to the 19” Rack “previously described in this chapter)
The 19 inch rack installed with the PLC base plate should be grounded according to the guidelines in the “Base plate safety grounding” section, as shown in the previous figure
(Fig. 2-11) Separate grounding wire is used for PLC base plate.

■ If concave mounting adapter bracket (IC693ACC313) is used, the grounding wire should be installed as shown in Figure 2-11
The ground wire is attached to the concave mounted adapter bracket. The additional ground wire connects the adapter bracket to the 19 inch rack mounted
The CI810B 3BSE020520R1 uses the same or equivalent hardware and the configuration after paint removal, as shown in Figure 2-11.
■ If a surface mounted adapter bracket, (IC693ACC308), is used, the ground wire should be removed from the base as shown in Figure 2-11
Board lead, fixed chassis ground to 19 inch rack. Use the same or equivalent hardware and paint removed configuration, such as
Figure 2-11.
Programmer grounding
To achieve normal operation, the computer (programmer) running PLC software must be connected to the common ground with the CPU base plate. through
Normally, ensure that the power cord of the programmer is connected to the same power cord (the same reference point) of the base plate to realize the common ground between the two
connect. If the common configuration cannot be ensured, use a port isolation device between the programmer and the PLC serial connection
(IC690ACC903)。 If there is a potential difference between the programmer ground and the PLC ground, there may be a risk of electric shock. Similarly, when
When they are connected through the programmer serial cable, the port or converter (if used) will be damaged.
Generally, aluminum PLC base plate is used to facilitate the shielding and grounding of the template. Some series of 90-30 I/O modules are connected to the template user
The shielding connection of the end connector is transmitted to the base plate through the template backplane connector. Other modules, such as CPU351352,
363,364 and 374 need separate shielding grounding. Relevant contents are discussed in the following sections.
Shielding grounding information of CPU and external port connection.
CPU and external ports, 351352363364, and 374 must have separate shielding connection
The port provides shielding. The grounding connection design of CPU351 and 352 is different from that of CPU363364 and 374
Methods are discussed separately..
CPU351 and 352 shield grounding
The CPU351 or 352 template must be connected to the rack ground of the template installation slot. There are two ways to achieve this ground connection. each
One CPU is equipped with an EMC grounding package (44A737591-G01), which contains a grounding cable, grounding bracket and screw.
1. CI810B 3BSE020520R1 can be connected from CPU to rack ground with grounding cable (sample No. 44A735970-001R01), which is in the same module
EMC grounding package provided together. One end of the cable has a connector socket for connecting the
Distribution terminal. The other end is a ring terminal for grounding connection. If the ring terminal contacts a painted
The panel, or the installed star lock washer, needs to remove the paint between the terminal and the panel, or scrape the paint
Remove metal to ensure good contact. Note: The star lock washer is suitable for shielding grounding, not for safety grounding.
