Hot Swapping Advantys STB Modules

Module Insertion

and Removal

The assembled base units on a DIN rail together with a NIM form the island bus.

Advantys STB modules can then be inserted into and removed from these base

units to complete or adjust the physical design.

Maximum

Insertion/

removal Cycles

The base units are designed to withstand up to 50 module insertion/removal cycles.

Note: If any of your modules are being used to provide operating power to a large

inductive load (at or near a maximum of 0.5 H), make sure that you turn any field

devices OFF before removing the field power connector from the modules. The

output channel on the modules may be damaged if you remove the connector while

the field devices are ON.

Note: If modules are inserted and removed from a base more than 50 times, the

integrity of the module-to-base contacts cannot be guaranteed. Be sure the history

of your modules is known before hot swapping them.
