FX70 Supervisory Controller Installation Instructions 13
Make power input connections to the terminals on the
LP-FXPM263-0 circuit board (cover removal is
required). Use the supplied earth grounding wires to
make a connection from a nearby earth ground to the
grounding lug on both the LP-FXPM263-0 power
supply and the controller (see Figure 9).
Wiring LP-FXPM263-0 Input Power and Earth
Ground
1. Remove power from the AC circuit being wired to
the LP-FXPM263-0.
2. Remove the LP-FXPM263-0 cover.
To do this, press in the four tabs on both ends of
the unit, and lift the cover off. If the FX70 is plugged
into the unit, you may need to slide it away to get to
the cover tabs.
3. Connect the supplied earth grounding wire to a
nearby grounding point (see Figure 9).
4. Make AC circuit connections line (mains) and
neutral to the terminals labeled
INPUT PWR .
5. Replace the cover on the LP-FXPM263-0 module.
Make sure all modules in the mounted assembly are
firmly connected together and secured.
Power and ground is also provided in wiring to remote
I/O modules through the 6-position connector.
However, note for each remote I/O module, you should
also connect its earth ground spade lug to earth ground
at that module’s location.
LP-FXPMxx-0 (Wall Mount AC Adapter)
You can order and adapt a wall mount AC adapter
(model LP-FXPMxx-0, where XX is either US, EU, or
UK) to power only the FX70. To use the adapter, you
must cut off its barrel plug end, then wire the two leads
into the top positions of the 6-position end connector
plug, observing and – polarity.
Note: I/O modules cannot be powered by the
LP-FXPMxx-0 adapter.
Note: Before plugging the wired connector plug into
the controller, check for 15 VDC at the proper polarity
using a multimeter (see Figure 10).
Do not power the controller until all other mounting and
wiring is completed. See
Powerup and Initial Checkout
on page 15.
IMPORTANT: Use copper conductors only. Make
all wiring connections in accordance with local,
national, and regional regulations. Do not exceed
the FX70 Supervisory Controller electrical ratings.
!
CAUTION: Risk of Property Damage
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas mettre le système sous tension
avant d'avoir vérifié tous les raccords de
câblage. Des fils formant un court-circuit
ou connectés de façon incorrecte
risquent d'endommager
irrémédiablement l'équipement.
IMPORTANT: Do not energize the AC circuit wired
to the LP-FXPM263-0 until all other controller
mounting and wiring is completed. See
Powerup
and Initial Checkout on page 15.
