Output Sequencing
Power up will always occur in the defined sequence stored within the device. Any preprogrammed
power down sequence, except the default, will not be in effect upon loss or removal of the VIPAC
source voltage. Sequenced power down can only be achieved by issuing the requisite commands
through the interface before removing the source voltage.
