2.2.1 Fitting onto/dismantling from a hat rail
Caution
Note the specifications on vibration and shock for
CPA−SC valve terminals with field bus direct
(see appendix A Technical specifications").
A hat rail fitting without a hat rail clamping unit is not
permitted.
·
If the terminal is fitted in a sloping position or if it is
subjected to vibration, secure the hat rail clamping unit
additionally
against sliding down with the retaining screws
intended for this purpose (see Fig.2/1)
against unintentional loosening/opening.
For fitting the CPA−SC valve terminal onto a hat rail, you will
require the mounting kit CPASC1−BG−NRH. This kit contains
2M4x10 screws and 2 clamping elements.
Fitting Proceed as follows:
1. Make sure that the fastening surface can support the
CPA−SC valve terminal (weights see appendix A).
2. Fit the hat rail (support rail EN 50022 35 x 7.5;
width35mm, height 7.5 mm). Make sure that there is
sufficient space for connecting the supply cables and
tubing.
3. Fasten the hat rail to the fastening surface at intervals of
approx. every 100 mm.
4. Fit the hat rail clamping unit to the rear of the CPA−SC
valve terminal (see Fig.2/1).
5. Hang the CPA−SC valve terminal onto the hat rail
(seeFig.2/1, arrow A).
