Phoenix Controls FSR100 - BACnet TX Controller Wiring; Phoenix Wiring Recommendations; Product Maintenance

©2010 Phoenix Controls Specifications subject to change without notice. Rev. 5/10 MKT-0266 MPC-1480 FAN STATIC RESET KIT—9 OF 12
At the BACnet TX controller (BACnet TP, SO and EO controllers cannot be used with FSR100)
• FSR power wire terminates on Terminal 25 (24VAC)
• FSR signal "+" wire terminates on Terminals 6 or 9 (MULTI_AI)
• FSR circuit common wire terminates on Terminals 7 or 10 (COM)
NOTE: A jumper wire is not required on this controller.
BACnet TX: any available MULTI_AI
PHOENIX CONTROLS WIRING RECOMMENDATIONS
• All circuits must conform to the requirements of an NEC Class 2 (dry) circuit
• Use multiple transformers instead of larger transformers when more than 100 VA is required
• Each pressurization zone should have either a dedicated single-phase primary circuit, or a secondary circuit disconnect
• Use cable sizes recommended by Phoenix Controls (see Table 2)
• Use stranded wire for ease of installation
• Follow good wiring practices:
• Locate cables away from sources of electrical interference (EMI/RFI)
• Do not run signal or communication cable in the same conduit or wire way as power cables
• If signal cable must cross power cables place these at a 90-degree angle
• Shield or drain wires, if required, should be wrapped with insulating tape to prevent contact with exposed conductors or
contacts
• Maintain a consistent color code or polarity all the way through the wiring system
• Power supply and signal isolation on I/O devices vary from manufacturer to manufacturer. Verify the wiring device manufac-
turer's recommendations for isolating power and signal common connections and maintain polarity
• Local and national electrical codes take precedence
• Strip 0.25" (6.4 mm) of insulation from each conductor, twist the strands, insert the conductor fully into the terminal block,
and tighten the terminal
• Test the wire connection by pulling on each conductor
• See “Phoenix Recommended Cables” on page 11, for approved cable manufacturers and wire types
MAINTENANCE
There are no user serviceable components in the Fan Static Reset Kit. If you suspect the pressure sensor is not sending out a signal,
first check the power wiring to ensure the sensor has power.
