Npaq MR Hardware Manual
2.2.1. AC Power Connections
AC input power to the Npaq MR 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 Npaq MR
drive chassis also functions as a 10 A breaker (supplementary protection only) for the incoming AC power.
The Npaq MR drive chassis is factory configured for one of four specified input voltages. The factory
configured AC input voltages, along with the current requirements for the Npaq MR drive chassis, are listed
in
.

The AC power cord/wiring specifications are listed in
. 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.
