2.2.1. AC Power Connections
AC input power to the Npaq 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 drive
chassis also functions as a 10 A breaker (supplementary protection only) for the incoming AC power.
Most Npaq drive chassis's can be configured for operation at any of four different AC input voltages (refer to
Section 2.4.). Before attempting to reconfigure the AC input voltage for the Npaq 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 Npaq drive chassis are listed in
W A R N I N G : The AC power cord is the Mains disconnect.

AC Input Voltage
100 VAC 50/60 Hz
115 VAC 50/60 Hz
200 VAC 50/60 Hz
230 VAC 50/60 Hz
The AC power cord/wiring to the Npaq 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.
D A N G E R : See the user documentation provided with your Npaq system to determine if the
Npaq chassis is limited to only one AC input voltage. Operation at other voltages may result in
damage to the Npaq chassis.
