Connecting and Disconnecting AC Power
Connecting an AC Shelf to Power
The T1000 with AC option has two AC-power C20 input connectors. Two (2x) C20/C19
type AC jumper cords are supplied with the AC power unit. To supply power to the T1000
unit, connect one end of each power cord to a power connector on the rear of the T1000 and
the other end of each power cord to a 120-240 volt 20 amp power distribution unit or
appropriate electrical outlet. Use a regulating uninterruptible power supply (UPS) to protect
the T1000 from power surges and voltage spikes, and to keep the T1000 operating in case of
power failure. See the following figure.
Figure 2-8 Connecting AC Power
Use the following procedure to connect the AC shelf to power:
Step 1 Isolate the power supply to ensure that the power supply cables are not energized. Use an
appropriate lockout/tagout procedure to ensure that the power supply cables are not
accidentally energized during the installation procedure.
Step 2 Connect the power cables to both power connectors.
