Wall Mount Installation Overview
Note:
Secure the triple gang-double deep electrical box to the stud(s) using the mounting
hole in the side of the electrical box (see figure above for mounting hole location). Drive the
mounting screws from the inside of the electrical box into the wall studs to prevent sharp
objects protruding into the electrical box.
2.3.1. 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.
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 m
anufacturer’s recommendations for isolating
power and signal common connections and maintain polarity.
Local and national electrical codes take precedence.
