WIRING
The 400CP will only operate with NSI dimming and control systems explicitly designed for interfacing with it.
Communication between the 400CP and the dimming system is via a 4 wire interface. Three wires carry the RS
422/485 bi-directional data. A fourth wire carries the DC voltage necessary for powering the unit.
Wiring cable between the 400CP and the dimming system is class 2 and should be at least 22 AWG, 4 conductor
shielded, twisted pairs. (BELDEN 8302, 8723; 22 AWG.)
The 400CP may be connected to the dimming system via parallel or daisy-chained wiring. Due to power supply
current demands, 400CP’s must be limited to 5 units per daisy chain run with 22 awg wire, or 10 units with 20
AWG wire.
The Luma-net panels feature plug on wiring terminals. The terminals may be unplugged from the panel to facilitate
ease of wiring and testing. Connect the terminals marked , remote-, common, and +15 VDC to the same
respective terminals on the dimming system and other 400CPs. Use one twisted pair for and remote- and
the other pair for common and +15 VDC.
The wiring to the remote lockout switch, if used, can be simple 2 conductor 22 AWG. Connect the wires from
the switch to the and lockout- terminals. Any panel or group of panels may be locked-out remotely by
interrupting the +15V supply to the panels. This should not affect any other panels still powered, or affect lighting
levels currently set.
IMPORTANT: Verify wiring is correct before powering system! Make sure nothing conductive may touch
pc board or components!
MOUNTING
The 400CP will mount in any standard double-gang electrical box with the 4 screws provided. See below paragraph
on system turn-on before final mounting of panels.
SYSTEM TURN-ON
It is very important that the system operation be verified one panel at a time. Else, an improper connection at
one panel would cause the entire system to not operate properly and may be difficult to diagnose.
After all terminal plugs have been wired and the dimmer system has been installed and tested, the installer is ready
to connect each panel to the system. Panels may be plugged-in while system is live, but the installer must take
care not to touch PC board or connections with fingers or metal objects. On daisy-chain runs, the panels closest
to the dimming system should be connected first.
400CP panels without dip switches must have their network ID programmed after the power is connected. The
panels that are provided with dipswitches should have the ID set before the system is powered. It is recommended
that the installer review the programming procedures for network ID before proceding.
A duplicate network ID
number will cause the entire network to malfunction.
Connect the first panel and immediately notice whether the POWER LED comes on, indicating power to the
panel. The BUSY LED should come on momentarily and then go out and stay out. This indicates a successful
reconfiguration of the network. If the BUSY LED flashes slowly, this indicates a duplicate ID number or wiring
problem. Program the ID number, if not already, and observe the BUSY LED. (Note, the busy LED also flashes
quickly when the program jumper is removed).
