 Mount the control on a
sheltered, vertical
surface, with the
electrical knockouts
facing down.
 Use a screwdriver to
tighten the screws in the
enclosure. Do not use a
drill or over tighten the
screws; this can crack
the enclosure and ruin
the watertight seal.
 Use the electrical knockouts for bringing wires or
cables into or out of the enclosure. Use watertight strain
reliefs or conduit connectors at all cable-entry points.
 Do not make additional holes in the enclosure; this
can damage the watertight seal or control components
and void the warranty.
Routing data wires
Routing data wires in the same conduit as, or beside AC power cables, can cause electrical
interference, erratic readings, and/or improper control. Data wires include all of the following:
 Temperature probe and humidity sensor cables
 Actuator feedback (potentiometer) wires
 Data communication wires, including RS-232/RS-485
 Any cable or wire that does not provide AC power
Guidelines for routing data wires

Do not run the wires in the same conduit as AC power cables.
 Do not run the wires beside AC power cables or near electrical equipment.
 When crossing other cables or power lines, cross them at a 90-degree angle.
If in doubt, do not run any wire or cable that is not an AC-power wire inside the same conduit or
beside other AC-power wires.
