Control Power Disconnect<br />
(behind door)<br />
These manually operated switches disconnect the static switch from the<br />
bypass line and from the critical load. They are normally ON (closed). Turn<br />
them OFF (open) only to isolate (disconnect) the static switch for<br />
maintenance procedures. For SCCT less than 1600A, the static switch<br />
disconnects are contactors that open automatically upon loss of bypass input<br />
power and close automatically when bypass power is restored. Control power<br />
fuse disconnects are used to manually open the contactors for maintenance.<br />
Press these two switches before closing Static Switch Disconnects when<br />
recovering from a shutdown that includes loss of Control Power. Green LED<br />
on means Control Power is available. Red LED on means Reset Switch<br />
needs to be pushed. Only SCCI and SCCC control cabi<strong>net</strong>s and SCCT<br />
1600A and larger.<br />
Normally ON. Fuseblocks that are labeled F7 through F10. Turn OFF Control<br />
Power only when required for maintenance procedures.<br />
