It is recommended that a dedicated AC service panel be used with the Option
11C system. Equipment unrelated to the Option 11C must not be connected
to this panel. Keep all lighting, fans, motors, air conditioning equipment, and
the like, as "electrically separate" from the Option 11C system as possible.
Power from each outlet must meet the input requirements of at least one
Option 11C power supply as itemized in Table 5 on page 44. Please check
power requirements for other system equipment and install additional outlets
if required.
Maximum rated input voltage 100-240 Volts RMS,
NEMA IG5-15R for 120 Volt, 15 Amp supply
NEMA IG6-15R for 208/240 Volt, 15 Amp supply
Site requirements
The following is a list of required site features for an optimal Option 11C
AC-powered system installation.
If the conditions below cannot be provided with a dedicated panel, the use of
an Isolation Transformer is recommended, as described under the heading
"Alternative AC-powered installation" on page 45 of this chapter.
• Dedicated circuit breaker panel
Provides power solely to the Option 11C system and its associated
hardware, such as TTYs, printers, and so on.
Note: It may not always be possible to power a complete system from a
single circuit-breaker panel. For example, an expansion cabinet may be
remotely located.
