• Note the warnings and instructions on the product and in the relevant operating
instructions.
• Ensure that there is a supply of correctly prepared compressed air (
Technical
data).
• Pressurise your entire system slowly. There will then be no uncontrolled move-
ments.

Installation
5.1 Mechanical
Note
• Installation and commissioning may only be performed in accordance with the
operating instructions and by qualified personnel.
• Handle the VPPM-...C1 with care so that the electrical connection is not dam-
aged. This could lead to an impairment of function.
• Make sure there is sufficient space for the cable
connection and tube couplings. In this way you will
prevent the connecting cable from being bent.
• Place the VPPM-...C1 as near as possible to the
consuming device. This leads to improved control
precision and shorter response times.
Fig. 6
Wall mounting (in-line valve)
• Fasten the VPPM-...C1 (1/8” and 1/4”) in the inten-
ded position with two M4 screws. In order to do
this use bracket type VAME-P1-A (see diagram).
When mounting the VPPM with the aid of the brack-
et, the VPPM-...C1 may only be loaded statically
(torque: approx. 1.5 Nm).
• Fasten the VPPM-…C1 (1/2”) with two M5 screws in
the intended position (torque 2.0 Nm).

H-rail mounting (in-line valve)
• Mount the H-rail adaptor on the VPPM-...C1 using the screws included (
x
”: M4
x 65,
¼
”: M4 x 77) (torque approx. 1.5 Nm).
• Hang the VPPM-... onto the H-rail.
• Secure the VPPM...C1 with the retaining screws of the H-rail adapter (torque
1.5 Nm).

5.2 Pneumatic (in-line valve)
• Remove the sealing elements from the compressed air ports.
• Attach the pneumatic tubing to the following connections (
Fig. 1):
– Supply port (1) Item.

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
should not be exceeded
(
ISO 8573-1:2010 [7:4:2]).
5.3 Electric
Warning
For electrical isolation of operating voltage:
• Only use PELV circuits as per IEC/EN 60204-1 (protective extra-low voltage,
PELV) for the electrical power supply.
Also observe the general requirements for PELV circuits in accordance with
IEC/EN 60204-1.
• Use only power sources which guarantee reliable electrical isolation of the
operating voltage as per IEC/EN 60204-1.
Protection against electric shock (protection against direct and indirect contact) is
guaranteed in accordance with IEC/EN 60204-1 by using PELV circuits (electrical
equipment of machines, general requirements).
Note
Long signal lines reduce the resistance to interference.
• Make sure that the signal cables are not longer than 10 m.
•
Check by means of the type plate to ascertain which valve variant you
have:

• Check whether the following options are required on the VPPM-...C1:
– measuring the actual voltage/current value
• Make sure that the cables are not squashed, bent or stretched.
• Use the pre-assembled cable with socket from Festo (Accessories
www.festo.com/catalogue). You can then guarantee that the specified protec-
tion class IP 65 and EMC are fulfilled.
• If a screened cable is used, earth the screening on the opposite end of the cable
from the VPPM-...C1.
Note
If the Y-connecting cable type NEBV-M12G8-KD-..-M12G5 is connected to CPX
I/O modules, the I/O modules will no longer be galvanically isolated.
• Connect the cables of the VPPM-...C1 in accordance with the circuit diagram.
