Requirements
Before connecting to AC mains power, make
sure that the mechanical installation, cooling
requirements, wiring, and controls are all set to
the configuration needed for your application.
Failure to do so could result in damage to the
unit or to other components in the system.
2.1
AC Mains
This amplifier will auto-detect AC mains
voltage from 100 to 240VAC, 50-60Hz. For
nominal 120VAC mains, the allowed operating
range is 70-135VAC, with 85VAC required for
start-up. For nominal 240VAC operation the
range is 140-270VAC. Use only the provided
AC cord to connect to AC mains.
All CA models have a fixed, non-defeatable
warm-up delay of two seconds to protect
against excessive in-rush current when first
