22 VL6C+ ™ SPOT LUMINAIRE USER MANUAL
SYSTEM CONNECTION
Connecting to System (Typical)
The VL6C+ Spot Luminaire requires a Smart Repeater unit for power and control by DMX512 consoles. (Refer to
"Smart Repeater Units" on page 12 of the Operation Overview section.) Lamp power is provided by an APS6 power
supply module installed in a Series 300 Modular Rack.
WARNING: Voltages high enough to injure or kill a person exists in the AC power rack when power is
applied. Verify that power has been removed from the AC rack before reconfiguring bus bars or performing
other internal work.
Three-Phase Power Source
The system is commonly connected to a three-phase AC power source. Three-phase AC power is produced by
alternators which contain three separate windings designed so that the voltages induced in them are equal in
amplitude and out of phase with each other by exactly 120 degrees. The outputs can be connected in one of two
methods to produce a three-wire, three-phase circuit: wye-connected source and the delta-connected source.
Figure 2-7: Three-Phase Power Diagram
In almost all cases the power source (house service) will be wye connected, but Series 200/300 equipment may be
connected either as delta or wye loads as required. The most obvious difference between delta and wye loads is that
a wye load uses a neutral and a delta load does not.
Note: The Series 200 powered outputs on the modular rack utilize the service neutral, and therefore must not be
used with a delta service, and requires the presence of a neutral, even when connected as a delta load.
