SENSORY/ACCESSORY
INSTALLATION
There are a variety of sensors and accessories available
for the RTU-OPEN. Some of these can be factory or field
installed, while others are only field installable. The
RTU-OPEN controller may also require connection to a
building network system or building zoning system. All
field control wiring that connects to the RTU-OPEN must
be routed through the raceway built into the corner post of
the unit or secured to the unit control box with electrical
conduit. The unit raceway provides the UL required
clearance between high and low-voltage wiring. Pass the
control wires through the hole provided in the corner post,
then feed the wires thorough the raceway to the
RTU-OPEN. Connect the wires to the removable Phoenix
connectors and then reconnect the connectors to the board.
See Fig. 72.
IMPORTANT
: Refer to the specific sensor or accessory
instructions for its proper installation and for rooftop unit
installation refer to base unit installation instructions and
the unit’s wiring diagrams.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury, death and/or equipment damage.
Disconnect and lock--out/tagout electrical power
before wiring the RTU--OPEN controller.
