STELLA-4 OPERATING INSTRUCTIONS
11
You can use the following tables as a guide for selecting
cable gauges and circuit breaker ratings for the system’s
operating voltage.
The minimum electrical service amperage required by a
Stella-188 is the sum of the Maximum Long-Term Continu-
ous Current for all Stella-4s connected to the Stella-188. An
additional 30% above the minimum amperage is recom-
mended to prevent peak voltage drops at the service entry.
NOTE: For best performance, the AC cable
voltage drop should not exceed 10 V, or 10%
at 115 V and 5% at 230 V. Make sure that even with
AC voltage drops that the AC voltage always remains
within the operating window.
Safety Issues
Pay close attention to these important electrical and safety
issues.
■ The Stella-188 requires a grounded outlet.
■ Do not use a ground-lifting adapter or cut the AC cable
ground pin.
■ Keep all liquids away from the Stella-188 to avoid haz-
ards from electrical shock.
■ Do not operate the unit if the power cables are frayed or
broken.
Audio Input
Up to eight channels of balanced audio are received via the
Stella-188’s Audio Input connector. Each of the eight audio
channels is hard-wired to the corresponding Stella-188
Channel Outputs, thereby allowing for easy distribution of
discrete audio channels for Constellation installations.
