2.1.1. AC Power Connections
AC input power to the XR3 drive chassis is applied to the AC power receptacle that is located on the rear
panel. The power cord connected to this receptacle also provides the protective earth ground
connection and may serve as a Mains disconnect. The main power switch located on the front panel of
the XR3 drive chassis also functions as a 10 A breaker (supplementary protection only) for the incoming
AC power.
Most XR3 drive chassis can be configured for operation at any of four different AC input voltages (refer
to Section .). Before attempting to reconfigure the AC input voltage for the XR3 drive chassis, the user
must verify that drive chassis does not contain an offline bus supply (Ex. 160LT Bus) or other option
that would limit or restrict the AC input voltages that it may operate at. These standard AC input voltages
along with the current requirements for the XR3 drive chassis are listed in
WARNING
: The AC power cord is the Mains disconnect.
Table 2-1:
Main AC Power Input Voltages and Current Requirements
AC Input Voltage
Input Amps (maximum continuous)
100 VAC 50/60 Hz
10 A
115 VAC 50/60 Hz
10 A
200 VAC 50/60 Hz
5 A
230 VAC 50/60 Hz
5 A
The AC power cord wiring to the XR3 must be rated for at least 300 V and have a minimum current
capacity of 10 A. The insulation rating for the AC power wiring must be appropriately rated for the
environment. The temperature rating of the insulation must be at least 80ºC. Environmental conditions
may necessitate the need to meet additional AC wiring requirements or specifications. AC wiring should
not be bundled with signal wiring to minimize EMI coupling and interference.
DANGER
: See the user documentation provided with your XR3 system to determine if the
XR3 chassis is limited to only one AC input voltage. Operation at other voltages may result
in damage to the XR3 chassis.
