If the unit is furnished with input power cables, the input power connections are made to the receptacles matching the input power plugs furnished located in close proximity to the Smart- Switch (typically within 3 feet). The input power connections to the SmartSwitch must include overcurrent protection included as part of the supply power distribution system. -
Page 13: Figure 4 Typical Input And Output Power Connections
Figure 4 shows the typical input and output power connections to the SmartSwitch. The Smart- Switch can accept up to 3 phase conductors, a neutral conductor and an equipment grounding con- ductor per input and output to match the specified supply voltage configuration. See the unit ratings table (Table 1) for the required number of phase and neutral conductors required for the particular SmartSwitch used. -

1 is available and the load is connected to source 1 before rotating the Bypass/ Transfer Control switch to “Bypass To S1” position. If source 1 is not available and the load is not connected to source 1 before the switch is rotated to the “Bypass To S1” position, power to the load may be interrupted. - Page 20 Transfer Control switch to “Bypass To S2” position. If source 2 is not available and the load is not connected to source 2 before the switch is rotated to the “Bypass To S2” position, power to the load may be interrupted. If the load is connected to source 1 and the SmartSwitch will not transfer the load to source 2, initiate a bypass to source 1.
