codes. For UL 924 emergency installation, secure an emergency power source for
control electronic power and line feeds as required.
2. Install conduit as required for low-voltage control wiring. All low-voltage terminations are
conveniently located behind the user interface of the panel. Two 12.7 mm (1/2 in)
knockouts are provided for low-voltage control wiring access.

Connect Wiring
Relays - Each relay has staggered output terminals for easy access to line and load connection.
A Phillips screwdriver and wire strippers are required for relay line and load terminations.
Control processor electronics AC input - A discrete circuit is required to power the control
processor; refer to
Terminations require only a precision flatblade screwdriver and wire strippers.
I/O terminations - All low-voltage control terminations are conveniently located behind the
user interface. Fold the user interface panel down to reveal termination points for DMX,
Network, Contact Input, 0-10V Control, and DALI control.
