Proper wiring prevents electrical noise

Electrical noise can produce undesirable effects on

electronic control circuits, thereby affecting

controllability. Electrical noise is generated by

electrical equipment, such as inductive loads, electric

motors, solenoid coils, welding machinery, or

fluorescent light circuits. The electrical noise or

interference generated from these sources (and the

effect on controllers) is very difficult to define, but

the most common symptoms are erratic operation or

intermittent operational problems.

Most noise problems can be prevented by using

proper wiring practices and techniques to prevent

coupling or inducing of electrical interference into

control circuits. The following simple wiring

practices should minimize interaction of noise and

controls:

• Connect humidifier and control cabinets to a

code-approved earth ground.

• Separate the line voltage wiring from low

voltage control circuit wiring when routing

electrical wiring inside the control cabinet.

• Use separate electrical conduits for line and low

voltage control wiring from the humidifier to

humidity sensors, airflow switches, etc.
