General Wiring Recommendations
2.2.1 Phoenix Controls Wiring Recommendations
•
Use cables recommended by Phoenix Controls (refer to
Phoenix Controls Cables on page 12
•
Stranded wire of at least 22 AWG is strongly recommended for all wire connections. Larger gauge wire may be required for long runs.
•
Follow good wiring practices:
•
Do not run the signal cable in the same conduit or wireway as the power cables.
•
If the signal cable must cross power cables, it is best to do so at a 90-degree angle.
•
Maintain a consistent color code or polarity all the way through the wiring system.
•
All wiring must comply with the National Electric Code (NEC) and local codes.
•
Do NOT
run this device's wiring in the same conduit as AC power wiring of NEC class 1, NEC class 2, NEC class 3 or with wiring used to
supply highly inductive loads such as motors, contactors and relays.
•
Tests show that fluctuating and inaccurate signal levels are possible when AC power wiring is present in the same conduit as the signal lines.
If you are experiencing any of these difficulties, please contact your Phoenix Controls Representative.
•
Local and national electrical codes take precedence.
Sensor connections:
•
Remove the front plate from the back plate to facilitate the wiring process.
•
Use a small flat screwdriver to tighten the terminal connector screws once the wires have been inserted.
•
The board connectors accept wires or flat cables ranging from 22 to 14 AWG (0.64-1.63 mm diameter) per pole. However, power cables
must remain between 18 and 14 AWG (1.02-1.63 mm diameter).
Power connections:
•
Power type cables (i.e., for power, 2- and 3-wire voltage and current inputs and outputs, as well as triac outputs) should be kept apart from
other types of wiring to avoid any ambient noise transmission to other wires.
•
Do not connect the universal inputs, analog/digital outputs or common terminals to earth or chassis ground (unless stated otherwise).
CAUTION
Turn off power before any kind of servicing.
Please note that there may be multiple power sources.
CAUTION
Phoenix Controls does not recommend wiring the sensor with power applied as accidental arcing may damage the product and
will void the warranty.
