Removing Tp4 Input Cards; Wiring Guidelines For The Nxp-Tpi/4 - AMX NetLinx NXP-TPI/4 Operation/Reference Manual

Removing TP4 Input Cards

1. Detach all connectors from the TPI/4 unit.
Always power-down the unit before attempting to remove or install input cards.
Failure to do so could result in damage to the TPI/4 and/or input cards.
2. Discharge any static electricity from your body by touching a grounded metal object or the
grounding bolt shown in FIG. 9 on page 14.
3. Carefully unscrew the two flat Phillips-head (top of each card) and round Phillips-head screws
(adjacent to each card connectors, as shown in FIG. 9 on page 14.
4. Carefully insert a grounded flat-head screwdriver into the groove located at the top of the unit
(above the input connector location).
5. Apply a slight vertical pressure (push-up) to loosen the pins connected to the main board.
6. Gently pull-up (vertically from the TPI/4) on the input card using a slight rocking motion to loosen
the connector pin attachments.
7. Once the card is removed, cover the empty slot with an input card cover (FIG. 9 on page 14).
It may be necessary to loosen and slightly move adjacent cards in order to maintain
the required "tight-seal" for both input cards. After the cards are adjusted to fit
together, tighten the connector screws to secure each card location.
8. Screw-in (clockwise) the two rounded screws at the rear and two (2) flat screws on top of the unit to
secure each blank card cover firmly to the TPI/4.
9. Repeat steps 2 through 8 to remove other cards, as required.
10. Ensure that all screws are secured, reconnect all rear TPI/4 connectors, and apply power.
Before installing the TPI/4 unit into an equipment rack, confirm that ALL REAR
CONNECTORS ARE PROPERLY ATTACHED AND ALL INPUT CARDS ARE
SECURED. CONFIRM THERE IS ACTIVE ICSNET and ETHERNET
COMMUNICATION.

Wiring Guidelines for the NXP-TPI/4

The NXP-TPI/4 requires a 12 VDC-compliant power supply to provide power to the TPI/4 via the
2-pin 3.5 mm mini-Phoenix PWR connector.
The incoming PWR and GND wires from the power supply must be connected to the corresponding
locations within the PWR connector.
Do not connect power to the TPI/4 until wiring is complete. These units should only
have one source of incoming power. Using more than source of power to the panel
can result in damage to the internal components and a possible burn out.
Apply power to the panels only after installation is complete.
