THEORY OF OPERATION
Rack System
A Rolling Rack houses an internal 3-phase, 400 Amp bus bar system which is connected to the house power service
by 4/0 Cam-Lok cables. The Rack accepts hot-swappable chassis modules that automatically connect to the internal
power bus. These Breaker Modules supply various types of AC power to individually protected branch circuits. The
branch circuits are conducted to remote Breakout Boxes by custom Trunk Cables and connectors capable of
powering 1200 watt luminaires at distances of up to 500 feet.
An integrated Signal Distribution System is provided where control data is applied at the Series 400 Rack. This data is
transmitted by the Trunk Cables to the remote Breakout Boxes where it is available for luminaires or other devices.
The Signal System will accept 10/100Mb/sec Ethernet, USITT DMX512, and DMX512-over-Ethernet, and will handle
all three protocols simultaneously. The DMX512 universes are available at each of two outputs on the Breakout Boxes.
The Menu Display on each Breaker Module can be used to configure which universe is output to each connector (refer
to
The Series 400 rack supports multiple input systems (software v2.0 or greater) and DMX merging (software v3.0 or
greater). All DMX512 inputs are configured with a Universe Number and a Source (A, B, C, *). (Outputs are only
assigned with a Universe Number.) The output device will send the numbered universe for the currently selected
source, i.e., if configured for universe 0 it will send either universe 0a, 0b, or 0c depending on which input is selected.
For complete instructions on setting up system input/outputs, refer to
The Front of House Breakout Module is connected by up to 500 feet of Trunk Cable to the Series 400 Rack where a
FOH Breaker Module sources power for the FOH System. Source-assignable Art-Net input using the Ethernet
connectors can replace functionality of the top two DMX inputs on a Front of House (FOH) Breakout Module. This
allows assignment of an Ethernet port to a source so that it can be switched over with the rest of the A, B, C sources.
WARNING:
A 400 Amp Disconnect
must be used
when house service is greater than 400 amps and more
than 10 feet from rack. 4/Ø feeders are rated for 400 amps or less. It is recommended that a PRG Series 400
400 Amp Disconnect be used. Refer to the Series 400 400 Amp Disconnect User Manual (02.9680.0200).
