13 Installation procedure – extrusion
13.1 Protection for sealed linear encoders
IP53 requires installation with sealing lips positioned away from splash water in accordance with
EN 60529/IEC 60529.
For ingress protection to IP64, please see section 14.8 on page 24 .
13.2 Fitment – general
Please note that fitment of the extrusion is independent of readhead mounting. For illustrative purposes
dowel pins are displayed, but the procedure for a datum edge is identical. Where neither an edge nor
dowel pins are available, begin by aligning extrusion mounting holes.*
Ensure the mounting faces are clean before installation.
* If a suitable reference edge or dowel pins are not available then we recommend that the extrusion is
checked against a dial gauge to ensure parallelism to the machine axis.

Loosely secure the extrusion to the mounting surface using M6
screws and washers as specified in section 11.3 on page 11 .
Using the correct tool, tighten the screws to a torque of 8 Nm.
Tighten all bolts, working from left to right.
(The numbers on the illustration show the order of tightening.)
Place the encoder on the mounting surface and firmly push
against mounting edge/dowel pins. Position the encoder to align
mounting holes.
See page 11 , section 11.2 and section 11.3 .
