Connect Control Wiring
Low voltage data connects to pluggable connectors on the left and right input/output boards
of the ERn enclosure. The ERn2 includes only one each left and right I/O board while the
ERn4 includes two of each.
• The left I/O provides termination for contact inputs and outputs, RS-232 serial, and
Ethernet control.
• The right I/O provides termination for LinkPower, auxiliary power, DMX in, DMX Out,
DMX through, and all enclosure option kits. The right I/O also provides termination for
option modules installed on the bottom module slot of the rack enclosure for enhanced
control and operation.
Note:
All low voltage control cables must be run in separate conduit from power wires in
accordance with local codes.
WARNING:
RISK OF DEATH BY ELECTRIC SHOCK! Failure to disconnect all power to
the rack before working in the enclosure could result in serious injury or
even death.
