Mounting The Linear Actuator; Mounting The Part-Turn Actuator; Using The Positioner In A Humid Environment - Siemens SIPART PS2 Compact Operating Instructions

CAUTION
Loss of degree of protection
Damage to device if the enclosure is open or not properly closed. The degree of protection specified on the nameplate or in
Chapter "Technical data (Page 34)" is no longer guaranteed.
● Make sure that the device is securely closed.
3.2

Mounting the linear actuator

For linear actuators, use the "linear actuator" mounting kit 6DR4004-8V or the integrated attachment.
You require different installation parts depending on the selected actuator type. The mounting kit is suitable for a stroke of 3
to 35 mm. For a larger stroke range, you require a separately ordered lever 6DR4004-8L. Refer to the detailed operating
instructions for further information on mounting.
3.3

Mounting the part-turn actuator

You require an actuator-specific VDI/VDE 3845 mount to install the positioner on a part-turn actuator. You receive the mount
and screws from the actuator manufacturer. Ensure that the mount has a sheet metal thickness of > 4 mm and
reinforcements. You also need the mounting kit 6DR4004-8D or the stainless steel coupling TGX: 16300-1556. Refer to the
detailed operating instructions for further information on mounting.
3.4

Using the positioner in a humid environment

Introduction
This information contains important notes for the installation and operation of the positioner in a wet environment with
frequent and heavy rains and/or continuous tropical dew. The IP66 degree of protection is no longer adequate in this
environment, especially when there is a risk of water freezing.
Favorable and unfavorable mounting positions
Avoid the unfavorable mounting positions:
● To prevent fluids seeping through during normal operation of the device, e.g. through exhaust air openings.
● Otherwise the display becomes poorly legible.
Figure 3-1 Favorable and unfavorable mounting positions
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.
