- Refer to note below -
If the required rated power (calculated A value) exceeds 160 kW, then install a second main power
supply. Divide the set of drives into two groups so they can be powered by different power supplies.
Refer to the IMPORTANT NOTE below.
IMPORTANT NOTE
. When using two power supplies on the same machine, they must make up two
independent groups with their own drives. Only the SERCOS-III BUS can be common for both
groups.
DANGER.
NEVER
connect the DC BUSES of the main power supplies in parallel.
ALWAYS
install the two groups separately.
