Grounding
An earth ground spade lug 0.187 in. (4.74 mm) is
provided on the controller for connection to earth
ground. For maximum protection from electrostatic
discharge or other forms of Electromagnetic
Interference (EMI), connect the supplied earth
grounding wire to this lug and a nearby earth ground.
Keep this wire as short as possible (see Figure 9).
Power Wiring
There are two power options for the controller: the
LP-FXPM263-0 power supply module (typical), or a
LP-FXPMxx-0 (Wall Mount AC Adapter).
LP-FXPM263-0
The LP-FXPM263-0 module lets you power the
controller (and if installed, connected I/O modules)
from AC line power, with a universal input range from
90–263 VAC. The LP-FXPM263-0 module provides
15 VDC to the controller, and installs on the left side of
the controller (see Figure 9).

making electrical connections. Contact
with components carrying hazardous
voltage can cause electric shock and
may result in severe personal injury or
death.
AVERTISSEMENT: Risque de
décharge électrique.
Débrancher
l'alimentation avant de réaliser tout
branchement électrique. Tout contact
avec des composants conducteurs de
