Requirements for product use
• Make these operating instructions available to the design engineer and installer
of the machine or system in which this product will be used.
• Keep these operating instructions during the entire product life cycle.
• Observe the rules/information of the trade association, the VDE specifications
and relevant national regulations at the location of use.
3.1 Technical requirements
General conditions for the correct and safe use of the product, which must be
observed at all times:
• Maintain the specified limits (e.g. for pressures, temperatures and electric
voltages).
• Make sure there is a supply of correctly prepared compressed air in accordance
with the specifications on the medium.
• Before mounting, remove particles in the supply lines through appropriate
measures. In this way, you protect the product from premature failure and high-
er wear.
• Pressurize your entire system slowly. This allows avoidance of abrupt move-
ments.
• Observe the warnings and instructions in these operating instructions.
• Use the product in its original state, without any unauthorised product modifica-
tions.
3.2 Qualification of trained personnel
Installation, mounting, commissioning, maintenance, repair and removal from
operation may only be performed by qualified personnel with knowledge and ex-
perience with electrical and pneumatic control technology.
3.3 Range of application and certifications
The products MS9-SV-...-C-V110-... and MS9-SV-...-C-V230-... fulfil requirements of
EC directives and are equipped with the CE marking.
Standards and test values, which the product must comply with and fulfil, can be
found in the section “Technical data”. The product-relevant EC directives can be
obtained from the declaration of conformity in the internet.

Mounting and installation
4.1 Mechanical
Note
Information about mounting of module connectors, sub-bases and mounting
brackets can be found in the operating instructions enclosed with the relevant
accessories.
• Place the MS9-SV-...-C as close as
possible to the location of use.
• Place the MS9-SV-...-C in such a way
that you have sufficient space for a
silencer.
• The mounting orientation is any de-
sired.
• Observe the flow direction from 1 to
2. Serving as orientation are the nu-
merals

on the product housing.

in the grooves of the in-
dividual devices. A seal

is re-
quired between the individual
devices.
2. Fasten the module connectors
MS9-MV with 2 screws.

• Make sure that the compressed air lines are connected correctly.
• Screw the connectors into the pneumatic ports using suitable sealing material.
Port 3 (thread size G1 or NPT1)
When exhausting a system through the MS9-SV-...-C, high sound pressure levels
are generated. We therefore recommend that you use a silencer.
Note
The silencer listed in the accessories U-1-B can be retrofitted on replaced only on
equipment with metric threads.
When retrofitting the silencer on a device with NPT thread at port 3, the cover of
the MS9-SV-...-C can be destroyed. When retrofitting, an adequate silencer with
NPT thread must be used.
• Screw the silencer into the pneumatic port 3.
• Make sure that there is unrestricted exhausting. Neither the silencer nor port 3
should be blocked.

Electrical connection
Warning
Electrical connections should be established only in the absence of voltage and
by qualified personnel.
Warning
Use only power sources which guarantee reliable electrical isolation of the oper-
ating voltage in accordance with IEC/EN 60204-1. Consider also the general
requirements for PELV circuits in accordance with IEC/EN 60204-1.
Note
Long signal lines reduce the resistance to interference.
• Make sure that the signal cables are not longer than 20 m.
