Festo VPPM- C1 Serie Mode D'emploi page 10

• Take into consideration the ambient conditions at the location of use.
• Remove all transport packing, such as protective conduit fitting, foils (polyam­
ide), caps (polyethylene), cardboard boxes. The material used in the packaging
has been specifically chosen for its recyclability (exception: oil paper = residual
waste).
• Observe the warnings and notes on the product and in these operating instruc­
tions.
• Use properly prepared compressed air (è Technical data).
• Pressurise the entire system slowly. There will then be no uncontrolled move­
ments.
Range of applications and certifications
In combination with the UL mark on the product, the information included in this
section is also applicable for compliance with the certification requirements of
Underwriters Laboratories Inc. (UL) for USA and Canada. Observe the following
notes from UL:
Note
• The Unit shall be supplied by a power source which fulfils the requirements on
a limited-energy circuit in accordance to IEC/EN/UL/CSA 61010-1 or on a
Limited Power Source (LPS) in accordance to IEC/EN/UL/CSA 60950-1 or
IEC/EN/UL/CSA 62368-1 or a Class 2 circuit in accordance to NEC or CEC.

5 Installation
5.1 Mechanical
Note
• Installation and commissioning may only be performed in accordance with the
operating instructions and by qualified personnel.
• Make sure there is sufficient space for the cable
connection and tubing connections. In this way you
will prevent the connecting cable from being bent.
• Place the VPPM-...C1 as close to the consumer as
possible. This leads to improved control precision
and shorter response times.
Wall mounting (in-line valve)
• Fasten the VPPM-...C1 (1/8" and 1/4") at the inten­
ded position with two M4 screws. To do this, use
bracket type VAME-P1-A (see figure). When mount­
ing the VPPM with the aid of the bracket, the
VPPM-...C1 may only be loaded statically (tighten­
ing torque: 1.5 Nm).
• Fasten the VPPM-...C1 (1/2") in the intended posi­
tion with two M5 screws (tightening torque
2.0 Nm).
H-rail mounting (in-line valve)
• Mount the H-rail adapter using the included screws (x": M4 x 65, ¼": M4 x 77)
to the VPPM-...C1 (tightening torque approx. 1.5 Nm).
• Hang the VPPM-... onto the H-rail.

Sub-base mounting (flanged valve)
• Fasten the VPPM-...C1 2 on the pneumatic mani­
fold rail type VABM-P1-SF-G18-...1.
• Tighten the mounting screws 3 (tightening
torque 1.5 Nm).
5.2 Pneumatic (in-line valve)
• Remove the covers from the compressed air supply ports.
• Attach the tubing to the following connections (è Fig. 1):
– Supply port (1) pos. 5
– Pressure output (2) pos. 2
• Mount a silencer at exhaust port (3) pos. 3 or remove the exhaust with ducted
tubing.
Operating medium
Note
Too much residual oil content in the compressed air will reduce the service life of
the valve.
• When using bio-oils (oils that are based on synthetic ester or native ester, e.g.
rapeseed oil methyl ester), the maximum residual oil content of 0.1 mg/m³
must not be exceeded (è ISO 8573-1:2010 [–:–:2]).
5.3 Electrical
Warning
Electric voltage
Injury caused by electric shock, damage to machine and system
• For the electrical power supply, use only PELV circuits in accordance with
IEC 60204-1/EN 60204-1.
• Use only voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204-1/EN 60204-1.
• Observe the requirements of IEC 60204-1/EN 60204-1 for PELV circuits.
Note
Long signal lines reduce the resistance to interference.
• Use signal lines that are shorter than 10 m.
• Check by means of the rating plate to determine which valve variant you have:
Designation on the rating plate
VPPM-...-V1...C1
Designation Voltage variant
Electrical setpoint 0 ... 10 V DC

• Make sure that the cables are installed free of crimping, kinking and stretching.
• Use the pre-assembled plug socket with cable from Festo
(accessories è www.festo.com/catalogue). You can then guarantee that the
specified protection class IP 65 and EMC are fulfilled.
• If a screened cable is used, earth the insulation at the cable end which is farther
away from the VPPM.
