NOTES
1. If the power consumption exceeds the power supplied, the DFI302 system may operate in an
unpredictable manner that may causes damages to the equipment or risk of personal injury.
Therefore, the power consumption must be calculated correctly and a detailed analysis should
be performed to define the installation of extra power supply modules.
2. The hardware revisions which are GLL1279 Rev1 and previous revisions do not support
redundancy feature.
3. To meet the EMC standards requirements, the wires’ length to the failure relay must be less
than 30 meters. The power supply of activated load by the failure relay must not be from
external network.
Calculating the Power Consumption
Since the power available in the power supply is limited, it is important to calculate the power
consumption of modules in use. The user can create a worksheet to summarize all supplied and
required current from each module and associated equipment (such as operator interface).
Example of worksheet with the module’s consumption, and some power supplies’ specification.
