Selecting and protecting auxiliary power supplies
(Original Document)
Introduction
Encoders, sensors and pre-actuators associated with the module require auxiliary power supplies (5VDC and/or 24VDC).
Type of power supply
Only use regulated power supplies to:
These power supplies must be independent enough (> 10ms) to override micro-power outages and ensure the module continues to run effectively.
Protecting power supplies
The power supplies for encoders, others sensors and pre-actuators need calibered fast-blow fuses against overloads and short-circuits.
Connection of the 0V supply to the protective ground:
The 0V supply must be connected to the protective ground nearest to the supply module output.
