Hi All,

Is it possible to use the UR 2 rack ( 6ES7400-1JA01-0AA0) for the H system with the CPU 412-5H (6ES7-5HK06-0AB0)?

This rack is not coming under the H system, but still I am able to configure the H system hardware configuration using that Rack and H system CPU.

 Dear Saravana kumar,

The answer is "Yes" You can.

To select the suitable rack that will accomodate CPUs of S7-400, please follow these steps:

• Use Qty: 1 of UR2-H Rack "6ES7400-2JA00-0AA0" or "6ES7400-2JA10-0AA0" (ALU type) if both CPUs will be installed near to each other and if you need more than 4 slots for each rack.
• Use Qty: 2 of CR3 Rack  "6ES7401-1DA01-0AA0" if you won't need more than 4 slots for each CPU rack. It can be used in both cases, if the two CPUs are close to each others or even if there are a long distance between them.
• Use Qty:2 of UR2 Rack "6ES7400-1JA01-0AA0" if you need more than 4 slots (up to 9 slots) for each CPU rack. It can be used in both cases, if the two CPUs are close to each others or even if there are a long distance between them. But normally, it's used if the CPUs are not close to each others.
