Can I install the e7w thermostat near other electrical wiring?

No, all wiring and controllers must be installed to minimize accidental contact with hazardous power and lighting wiring. Never place 24VAC or communications wiring near bare power wires, lightning rods, antennas, transformers, or steam/hot water pipes. Keep wiring and controllers at least six feet from large inductive loads like power distribution panels, motors, and lighting ballasts to avoid electrical interference (Page 4).
