Note
F0395 cannot be cleared via power cycle. F0061, F0062 and F0063 can only be cleared via
power cycle.
In case of a swap fault check, whether the MMC is defective or a parameter set clone00.bin
is available or the parameter set is valid.
A valid parameter set means, it is not from a different type (eg. CU20S DP and CU240S or
failsafe and standard CUs)
Rules regarding swap and hot swap
There are a number of scenarios where a swap or hot swap can take place, each with their
own unique set of conditions that must be observed.
Danger
Do not attempt to hot swap a power module (PM)
Before attempting to swap a PM it must be fully powered-down. Any attempt to swap-out a
PM when power is still applied could result in death of personnel and severe damage to
property and equipment.
Warning
Swap restrictions
Before performing a swap take care of the following:
• It is the responsibility of the user to ensure that only CUs of the same type are swapped
• It is the responsibility of the user to ensure that the MMC contains the correct parameter
set
• It is the responsibility of the user to ensure that only PMs of the same type and power
rating are swapped.
• It is the responsibility of the user to ensure that the application is in a safe state before
any swap of equipment is performed.
