The Smartpack easily switches from single phase to three phase operation, or vice versa, by moving the power feed from the L2 terminal in the pack to either the L1 or L3 lug on the power board. Each Smartpack ships with a document including illustrations for this purpose.
The Smartpack will operate within a voltage range of 85-140VAC, 47-63Hz. This will allow the Smartpack to be used in countries with a power cycle of 50Hz.
