Installation and Operation Manual
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 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 wiring
practices should minimize interaction of noise and controls:

earth ground.

circuit wiring when routing electrical wiring inside the control
cabinet.

control wiring from the humidifier to humidity sensors, airflow
switches, etc.
t %POPUVTFDIBTTJTPSTBGFUZHSPVOETBTDVSSFOUDBSSZJOH
commons. Safety grounds should never be used as a conductor or
neutral to return circuit current.
IMPORTANT:
Do not use shielded (screened) cable for
probe wiring.
IMPORTANT:
Locate the control cabinet so that wire
lengths are 50' (15 m) or less to the
humidifier.
IMPORTANT:
When routing modular cable inside the
control cabinet, route cable away from
all power wiring and connect the male
modular plug into the Vapor-logic
3
printed
circuit board-mounted female modular
receptacle, J2. Push the male plug in until
you hear a “click.” (The cable should be
plugged into the keypad/display as well.)
CAUTION:
When making penetrations in the control
cabinet, protect all internal components
from debris and vacuum out cabinet
when finished. Failure to comply with this
warning may damage sensitive electronic
components and void the DRI-STEEM
warranty.
