2.3 Source #1 AC Input Connections
The connections to be made are the three phases, neutral (if used) and ground cables of input AC Source #1 to the
STS. The main 3-phase cables of input Source #1 are terminated at the Source #1 input busbars. Neutral (if
supplied) and Ground cables are terminated at the Neutral (N) and Ground (GND) busbars respectively. All cables
from Source #1 should be run in a single conduit separately from all other cables (power supply or computer-system
interconnection cables). They should not pass near interference-emitting equipment or sensitive loads. Complete
wiring instructions for your installation are provided on the installation drawings supplied with the equipment. See
Figure 1-5 and 1-6, refer to table 1-1 and 1-2 for details.

supplied) and Ground cables are terminated at the Neutral (N) and Ground (GND) busbars respectively. All cables
from Source #2 should be run in a single conduit separately from all other cables (power supply or computer-system
interconnection cables). They should not pass near interference-emitting equipment or sensitive loads. Complete
wiring instructions for your installation are provided on the installation drawings supplied with the equipment. See
Figure 1-5 and 1-6, refer to table 1-1 and 1-2 for details.
