Note
The VTSA valve terminal with type 03 electronics is not
intended for H−rail mounting. Use wall mounting for this
valve terminal variant.
Caution
Make sure that the H−rail can support the weight of the
VTSA... valve terminal and can absorb torsion e.g.
through the vertical stacking.
When mounting the valve terminal onto an H−rail, note
the specifications in standard EN 60715 and the specifi
cations on vibration and shock in the section Technical
data" in Appendix A.
H−rail mounting without an H−rail clamping unit is not
permitted.
If the terminal is mounted in a sloping position or if it is
·
subjected to vibration, secure the H−rail clamping unit
additionally
against sliding down with the retaining screws
intended for this purpose (see Fig. 2/1, item 2)
against unintentional releasing/opening.
In order to mount the valve terminal onto an H−rail you will
require the following mounting kits:
For VTSA... valve terminals with multi−pin nodes:
Mounting kit type CPA−BG−NRH.
This kit contains 2 M4x10 screws and 2 clamping compo
nents.
For VTSA... valve terminals with CPX terminal:
