Installation
Mounting of cable
The PVE-EX is equipped with a top part that holds the cable gland for cable installation.
1. Remove the insulation of an appropriate length to expose the wires.
If wire shall be connected to the earth terminal, make sure to have insulation enough to crimp into
the cable shoe and attach properly to the chassis.
Cable material must be according to the specification.
2. Strip the wires so that a suitable length of cooper is exposed.
3. Insert wires and cable through the gland and grommet.
4. Insert wires into screw terminals and tighten the screws.
5. Pull the cable back to the position where the cable insulation is still going through the grommet.
6. Immerse the terminal compartment and mate the male and female connector.
7. Ensure that the O-ring is properly seated in its groove and that excess wires are not trapped between
the two elements.
8. Tighten the screws (M6 x 12 mm) to the specified torque 6 ± 1 N•m.
9. Tighten the gland to the specified torque in which the cable is locked correctly, then fix the safety
wire (not included).
Use screws made from stainless steel grade A4 or stronger (enclosed).
Cable gland
The PVE-EX is required to be installed with a cable specified to the surrounding conditions and to the
given diameter of the cable gland. There are two options available for cable glands:
• Supplied built-in cable gland (certified with the product)
• Pre-certified standard cable gland (M20 x 1.5 mm threaded entry and 20 x 1.5 mm O-ring).
Supplied built-in cable gland
The PVE-EX has a built in cable gland for cable installation. The cable gland and grommet ensures that
the internal components are not exposed to the outside. Furthermore, the cable gland arrangement has
to retain any flame and pressure that can occur inside the PVE-EX.
1. Choose the grommets delivered with PVE-EX for different cable diameters. (see the table below)
The cable gland needs to meet the diameter of the cable and to the PVE-EX.

PVE-EX Ex eb mb version Group II Electro-hydraulic Actuator for PVG 32/100/120/128/256
Maintenance, service and troubleshooting
PVE-EX installation, start-up and operation
The inspection intervals and definitions are to be seen in the standard EN/IEC 60079-17 and the
corresponding Inspection schedules-table. Operators must under no circumstance try to repair or open a
PVE-EX. A failing or damaged PVE-EX is to be replaced.
The PVE-EX module has a built- in thermal fuse. If the temperature rises above 102°C ±3°C, the thermal
fuse will disconnect the power to the PVE-EX. It is not possible to change the thermal fuse. The PVE-EX
actuator needs to be replaced.
W
Warning
The installation must be performed as intended in order to have a safe system and a proper functional
application. In a case of damage to enclosure, plug or cable, the PVE-EX actuator must be replaced. Please
refer to the information in this manual for assistance, or consult with a professional.
W
Warning
All national safety regulations must be fulfilled in connection with installation, start-up and operation of
Danfoss PVE-EX electrical actuation's. Furthermore, the requirements of the Declaration of Conformity
and national regulations for installations in potentially explosive atmospheres applies as well.
Disregarding such regulations involves a risk of serious personal injury or extensive material damage.
W
Warning

If failure, damage or defect occurs, the PVE-EX has to be replaced.
A failing PVE-EX must under no circumstance be repaired.
No modifications, which could damage the explosion-safety and protection, are allowed to the PVEEX, the cable gland, or on the cable.
Demounting a PVE-EX must be done in an atmosphere with no potential for explosions.
The machine and system approval has to be issued before using the PVE-EX in potentially explosive
atmosphere.
The manufacturer has the application responsibility and is solely responsible for the safety of the
system.
Deviations from recommended torque when mounting parts can harm performance and the PVE-EX.
Do not adjust, bend or damage the position transducer (LVDT) as this will influence the safety and
performance.
If replacing the PVE-EX, the electrical and the hydraulic systems must be turned off and the oil
pressure released.
Hydraulic oil can cause both environmental damage and personal injuries.
Actuator replacement can introduce contamination and errors to the system. It is important to keep
the work area clean and components should be handled with care.

Warnings
PVE-EX warnings
W
Warning
All brands and all types of directional control or proportional valves, which are used in many different
operation conditions and applications, can fail and cause serious damage.
You must perform a risk assessment. The machine builder/system integrator alone is responsible for
making the final selection of the products and assuring that all performance, safety and warning
requirements of the application are met.
The process for choosing the control system and safety levels is governed by the Machinery Directive
2006/42/EC and EU harmonized standard EN 13849 (Safety related requirements for control systems).
W
Warning
The installation must be performed as intended in order to have a safe system and a proper functional

Warning
Not applying to the Operational Conditions can compromise safety.
A PVG with PVE-EX can only perform according to specification if conditions in this Installation Guide
are met.
In particularly exposed applications, protection in the form of a shield is recommended.
If the PVE-EX is in fault mode the quality of performance and validity of feedback is limited depending
on the fault type.
Error signals from more PVE-EX’s must not be connected together. Inactive error pins are connected
to ground and will disable any active signal. Error pins are signal pins and can only supply very limited
power consumption.
After replacement of actuators or cables wiring quality must be verified by a performance test.
By actuation outside specified supply voltage range PVG will have reduced performance.
The PVE-EX is not designed for use with supply voltage outside nominal.
Obstacles for the Pilot oil can have direct influence on spool control.
Reduced pilot oil pressure will limit spool control.
Pilot oil pressure outside specification can damage the PVE-EX.
The PVE-EX must be installed so that the flanged joints are not within 0.5 mm of a solid object that is
not part of the PVG.
