Setup
Network Wiring
When wiring the Cresnet network, consider the following:
Use Crestron Certified Wire.
Use Crestron power supplies for Crestron equipment.
Provide sufficient power to the system.
CAUTION: Insufficient power can lead to unpredictable results or damage
to the equipment. Use the Crestron Power Calculator to help calculate how
much power is needed for the system (
www.crestron.com/calculators).
For networks with 20 or more devices, use a Cresnet Hub/Repeater (CNXHUB) to
maintain signal quality.
For more details, refer to “Check Network Wiring” which starts on page 23.
Installation
Ventilation
The PAC2 should be used in a well-ventilated area. The venting holes should not be
obstructed under any circumstances.
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. Consider using
forced air ventilation or incrementing the spacing between units to reduce
overheating. Consideration must be given if installed in a closed or multi-unit rack
assembly since the operating ambient temperature of the environment may be greater
than the room ambient temperature. Contact with thermal insulating materials should
be avoided on all sides of the unit.
Mounting in a CAEN
CAUTION: The Crestron Automation Enclosure (CAEN) houses equipment that
needs to be air-cooled. Therefore, mount in a well-ventilated area. The ambient
temperature range must be 41° F to 113° F (5° C to 45° C). The relative humidity
must range from 0% to 90% (non-condensing). Allow adequate clearance in front of
the vented cover for servicing and ventilation.
NOTE: The CAEN is intended for indoor use only.
NOTE: Reliable earth grounding of equipment mounted in a CAEN should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (for example, use of power strips).
The PAC2 has two flanges that allow the unit to be mounted in a CAEN. For more
information about the CAEN, refer to the latest version of the CAEN – Automation
Enclosures Installation Guide (Doc. 5940). The following procedure assumes two
CLX-Series modules have been installed in a double-wide CAEN. Complete the
procedure below to attach the PAC2 to the CAEN. A #2 Phillips screwdriver is
required.
