Assembly of the Terminal Base (TB511, TB521 or TB541)

  1. The Terminal Base is put on the DIN rail above and then snapped-in below. The disassembly is carried out in a reversed order.

Disassembly of the Terminal Base (TB511, TB521 or TB541)

Step 3: Mount I/O Terminal Unit (TU515, TU516, TU531 or TU532)

Assembly of the I/O Terminal Unit (TU515, TU516, TU531 or TU532)

The I/O Terminal Unit is snapped into the DIN rail in the same way as the Terminal Base. Once secured to the DIN rail, slide the I/O unit to the left until it fully locks into place creating a solid mechanical and electrical connection.

Altogether 7 I/O Terminal Units can be combined with the Terminal Base.

If both of the following conditions are fulfilled, max. 10 I/O Terminal Units can be combined with the Terminal Base:

  • PS501 as of version V1.2
  • CPUs as of firmware V1.2.0

Maximum configuration (1 Terminal Base plus 7 I/O Terminal Units)

*) If both of the following conditions are fulfilled, max. 10 I/O Terminal Units can be combined with the Terminal Base:

  • PS501 as of version V1.2
  • CPUs as of firmware V1.2.0

Disassembly of the I/O Terminal Unit (TU515, TU516, TU531 or TU532)

A screwdriver is inserted in the indicated place to separate the Terminal Units.

Step 4: Mount the CPU

Assembly of the CPU

Press the CPU into the Terminal Base until it locks in place. After that, press the module with force of 100 N onto the Terminal Base.

The disassembly is carried out in a reversed order.

Disassembly of the CPU

Disassembly: Press above and below, then remove the CPU.

Step 5: Mount the Communication \ Module

Assembly of a Communication Module

The Communication Module is first inserted below, then clicked-in above.

Attention

:strong:Risk of malfunctions and damages to persons!

Unused slots for Communication Modules are not protected against accidentally touch. Dust and Dirt may cause contact problems and malfunctions.

Unused slots for Communication Modules must be covered with Dummy Communication Modules (TA524 TA524 - Dummy Communication Module).

The disassembly is carried out in a reversed order.

Disassembly of a communication module

Disassembly: Press above (and below), then swing out the communication module and remove it.

The following figure shows a Terminal Base with a CPU and two communication modules inserted.
