4.4 Using the positioner in a humid environment
Introduction
The positioner enclosure provides IP66 protection with an intended installation position. It can
therefore be operated in a moist or wet environment in the mounting positions shown below.
Do not use other mounting positions since it would then be possible for liquids, fluff, fibers or
dusts to enter the device via the exhaust openings.
Favorable and unfavorable mounting positions
Avoid the unfavorable mounting positions:
● To prevent fluids seeping through during normal operation of the device, e.g. through
● Otherwise the display becomes poorly legible.
Figure 4-7
Additional measures to prevent liquids from seeping through
Take additional measures to prevent liquids from seeping through if the conditions force you
to operate the positioner in an unfavorable mounting position.
Additional measures required to prevent liquids from seeping through depend on the selected
mounting position. You may also require:
● Gland with sealing ring, e.g. FESTO: CK - 1 / 4-PK-6
● Approximately 20 to 30 cm plastic hose, e.g. FESTO: PUN - 8 x 1.25 SW
● Cable tie; the number and the length depend on the local conditions.
