Installation and Configuration
Npaq® Hardware Manual
All low voltage connections must be made using cables/wires sized for the maximum currents that will be
carried. Insulation on these cables/wires must be rated at 300 V if this wiring can come into contact with
wiring operating above 100 V (AC & Motor wiring). Low voltage wiring should not be bundled with AC and
motor wiring to minimize signal disturbances due to EMI interference and coupling.
N O T E :
The machine integrator, OEM or end user is responsible for meeting the final protective ground-
ing requirements of the system.
W A R N I N G : Before powering up the Npaq, verify that all drive modules and cables to the
Npaq have been properly installed. Refer to the remaining chapters of this manual for
installation and configuration procedures.
N O T E :
Confirm that the AC power is the correct voltage before turning on power to the Npaq. If the -
LineSel option is present, the user may verify the Soft Start/Voltage selection switches, as described in
The ex5 V power is fused by re-settable (semiconductor) fuses located on the Rear Panel Interface
board. These fuses protect the system should a fault or overload condition occur with the optical encoders,
joystick, I/O bus, or Miscellaneous I/O connectors. This fuse will reset itself when the overload condition is
removed (power may also need to be turned off to reset the fuse). In addition to this fuse, each drive module
has a safety fuse. To access the safety fuse, unscrew the module from the front panel and pull out the
module.
Some Npaq systems may use +12 V for the limit switch supply (Special request / requirements). The Npaq
can also provide an ex24 V output for Brake applications. The +24 V Brake output is only provided
when the Brake option is used.
