1. Installation
DPT-D series actuators are high precision
instruments with sub-nanometre resolution
and stability. They require careful handling
and must not be dropped or subjected to
unnecessary torque on installation (see
section 3).
1.1 Mounting into a system
The DPT-D series of actuators can be
mounted by means of an M3 screw
requiring 3mm maximum of thread
engagement. A pair of Ø1.6mm dowels
requiring 2mm maximum of engagement
as shown in Figure 1 can be used for
accurate location if required. Mounting
surface for the actuator base should be at
to better than 5µm. Full dimensional details
are available on the Installation drawing
PA0099-IN-001.

Installation and Handling Instructions
2. Operation
Connect the actuator to the corresponding
controller socket, ensure the screw lock
posts are secured to a torque of 25-30cNm.
Avoid prolonged use in a high humidity
environment and extended use at high
voltage as this may lead to an increase
in leakage current which in turn will
dramatically reduce actuator lifespan.
Use the DPT-D actuators only in
conjunction with original calibrated
1.2 Actuator Connector
Keep the EMC cap tted to the actuator
connector until ready to connect to the
controller. Ensure the controller is switched
off before installing or removing cables.
Static discharge to the connector may
cause damage, ensure that all personnel
handling the unit are adequately grounded.
3. Attaching or changing external
load to the head
When attaching an external load or
accessory to the actuator head always use
the spanner supplied. Failure to comply
may result in damage. The maximum
tightening torque applied must not exceed
50cNm. There is no anti-rotation feature on
the actuator head: If head rotates damage
will occur.
4. Maintenance
Do not contaminate the surface of the
assembly by exposing it to conductive or
corrosive substances. It is recommended
that isopropanol is used when cleaning the
assembly. Do not use acetone.

Mounting the DPT-D on the housing is not
recommended and may be detrimental to
hysteresis and thermal drift. For optimum
performance mount the DPT-D vertically.
Apply only axial forces to the actuator head
referring to the DPT-D datasheet, bending
or torsion forces should be avoided.
