Mounting Safety Modules
(Original Document)
About us
Introduction
All Premium range safety modules are standard format and therefore occupy one single position in the TSX RKY••• racks.
They can be installed in any position in the rack, with the exception of the first two (PS and 00), which are reserved for the rack supply module (TSX PSY•••) and the processor module (TSX 57•••) respectively.
NOTE: The modules can be handled without switching off the rack supply, in complete safety and with no risk of damaging or disturbing the PLC. It is, however, imperative that the module cable be unplugged in order to deactivate the safety outputs before removing the output terminal block.

The following diagram shows the procedure for mounting a safety module in the rack.
