Power-Supply Module PS204 for Redundant Power Supply
Description
If you want to equip a SIPROTEC 5 device with a redundant power supply, you need the power-supply module
PS204. For devices with a 2nd row, a 2nd PS204 module is necessary additionally to the PS203 module.
The power-supply module PS204 has no additional functionality. It functions exclusively as a redundant power
supply in the device and is only active if the main power supply or its auxiliary voltage supply fails.
The rated-voltage variant of the power-supply module PS204 must always match the power-supply module
PS201 of the base module.
Device Prerequisites for Redundancy
•
The base module must be device version C or later. You can find the device version on the name plate
(see the figure in the chapter 6.15 Modular Device Name Plate). For older devices (older than release
status C), it is not possible to achieve redundancy by retrofitting a PS204.
•
The firmware and configuration of the device must be version V7.82 or higher.
NOTE
The CB202 PCB assembly is not supported by the redundant power supply. If the power supply of the
CB202 fails, a PS204 in the device does not function as a redundant power supply. The device goes into
fallback mode.
Positioning Specifications
The power-supply module PS204 is always provided as part of the expansion module and must always be
mounted on the very right position (front view) in the corresponding row, for example, at position 3 for a 1/2
device.
