3.3.1 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.
•
See
Phoenix Recommended Cables on page 33
for approved cable manufacturers and wire types.
•
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 manufacturer’s recommendations for isolating power and signal common connections and
maintain polarity.
• Local and national electrical codes take precedence.
