Power Wiring
The System Pilot is a wall mounted device. Refer to the System Pilot
Installation and Operation Instructions (Catalog # 533-30013) for
instructions on mounting the System Pilot on the wall.
The Universal Controller uses any standard, Class II, SELV-
compatible, field-supplied 24 Vac power source. The power require-
ment is as follows:
60 VA @ 24 Vac + 15%
All installation wiring must conform to the following requirements:
• All applicable local codes, ordinances, and regulations must be
observed.
• All module power wiring must be as short as possible.
• Primary power wiring must be run in separate conduit or Electrical
Metallic Tubing (EMT) from the CCN Communication Bus, sensor
field wiring, and device field wiring.
The power supply must be minimum 60VA, Class II rated, with a fused
secondary. A 3.3A slow blow fuse is recommended. Install it according
to the manufacturer’s installation instructions.
Warning: Do not plug in or turn on the power supply at this time.
Module power wiring can be completed only after the module is installed
in the enclosure. This section describes how to wire power connections
to the Universal Controller.
The CCN Installation and Start-up Manual (808-211) provides U.S.
and international wire specifications for various applications and lists
recommended wire vendors.
Warning: When using a 24 Vac power supply to power the Universal
Controller, do not use it to also power non-controller type
devices such as sensors and actuators. If sharing power
between other CCN controllers, you must maintain phasing
between devices (see Power Requirements in Appendix
C).
