Mains Breaker
2U & 3U amplifiers have a push-type circuit breaker,while 4U units have
a throw-switch style breaker. If the unit’s breaker trips repeatedly, the
amplifier needs servicing.
2
IEC Power Cord Connector
On 2U amplifiers, a standard IEC power connector is located on the
rear panel of amplifier.The connector accommodates a standard IEC line
cord, included in the amplifier box. Should this cord need to be
replaced,only a cord with the same current rating should be used.3U
& 4U units have a captive power cord.
3
AC Mains / Active LED indicators
The AC mains yellow LED indicates that the amplifier is attached to a
power source.The active green LED indicates that the amplifier has been
turned on and is operating.
4
Sequential turn on/off Connectors
These connectors can be wired to a contact closure for remote turn-
on and to other CKi amplifiers for sequential turn-on (STO).
5
Fault I/O Connector
This output is a contact closure that can be used to report a fault con-
dition (e.g.an open output relay) in the amplifier.
