The device can be damaged, destroyed, or its functionality impaired through improper mounting.
• Before installing ensure there is no visible damage to the device.
• Make sure that process connectors are clean, and suitable gaskets and glands are used.
• Mount the device using suitable tools. Refer to the information in Construction (Page 39) for installation torque
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
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 exhaust air openings.
● Otherwise the display becomes poorly legible.
