2.3.3 Fitting CPX terminals with Midi/Maxi pneumatics onto a hat rail

Festo P.BE−CPX−SYS−EN en 0503b
For fitting the valve terminal onto the hat rail you will require
a hat−rail clamping unit type CPX−03−4,0 (Midi) or type
CPX−03−7,0 (Maxi).
Caution
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 sub
·
jected to vibration, secure the hat−rail clamping unit
additionally
against sliding down and against unintentional the
locking screws (see Fig. 2/12, item 6)
with the locking screws intended for this purpose
(item 6).
Please note
If the terminal is fitted in a horizontal position and the
load is at rest, it is not necessary to use the screws to
secure the hat−rail clamping unit (see Fig. 2/12, item 6).
If your terminal does not have a hat−rail clamping unit,
you can order this and fit it at a later stage.
Whether Midi or Maxi clamping elements are to be used
depends on the end plates fitted (Midi/Maxi).
The CPX terminal has been prepared for fitting onto a wall. To
compensate for the difference in height, two spacer rings
have therefore been placed on both the right−hand end plate
and on the pneumatic interface at the factory.
Recommendation: Use a suitable tool to remove the
·
upper spacer rings (e.g. scratch them off with a screw
driver). There is then sufficient space to hang the terminal
on the hat rail.
