Network Room Modules Installation Guide
Figure 5: Terminal Block Connection
• Terminations are made on the terminal block in the base of the module,
which is accessible after removing the cover from the base.
• The screw terminals accept up to 1.5 mm
2
(16 AWG) wires.
• Keep low-voltage wiring separated from power line voltage wiring.
• Do not run wiring close to transformers or high frequency generating
equipment.
• Complete and verify all wiring connections before applying power to the
module.
• Use screw terminals RT+, RT-, and COM to connect to the FX controller
display (local ink) bus terminals (LL+, LL-, and COM, respectively).
Note:
RT+ and RT- are
polarity sensitive
and are
not
interchangeable.
• If shielded cable is used, connect the shield to a clean earth ground at
one end only.
• Connect the power supply voltage to the terminals as marked:
- 15-24
VAC/VDC
and COM (common) for the LP-NRM0xx-000C
Series NRM
- 15
VDC
and COM (common) for the LP-NRM5xx-000C and
LP-NRM6xx-000C Series NRMs
Service Port
The service port is located on the lower edge of the module. There are two
different types of service ports, depending on the NRM Series you are
using:
4-Pin Service Port
See Figure 6 for service port wiring for LP-NRM0xx-000C Series NRM.
Use the 4-pin service port to download applications into the connected FX
Controller using the Programming Key (pass-through feature). The NRM
supplies power to the Programming Key.
6-Pin Modular Jack Service Port
See Figure 7 for service port wiring for LP-NRM5xx-000C and
LP-NRM6xx-000C Series NRMs.
Use the 6-pin Modular Jack service port to connect a Medium User
Interface (MUI) for monitoring and adjusting parameters in the control
application of the connected FX controller. The NRM supplies power to the
MUI from the FX controller through the 6-pin Modular Jack service port.
