CAUTION
EMI Noise Introduction.
Risk of erratic system operation.
Keep wiring at least one ft (305 mm) away from large
inductive loads such as motors, line starters, lighting
ballasts and large power distribution panels. During
installations, try to avoid areas of high EMI noise.
Run wall module wiring separately from 50 Vac or
greater power wiring.
