Installation Guide
PVE-EX AEx db version, Class I: Zone 1/Divison 2 – Electro-hydraulic Actuator for PVG 32 and PVG 128/256
General information
Installation and Maintenance standards:
•
EN/IEC 60079-14 Explosive atmospheres - Part 14: Electrical installations design, selection and
erection
•
EN/IEC 60079-17 Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
The PVE-EX is in conformity with listed EU Directive (s) and EU harmonized standards:
•
EMC Directive 2004/108/EC
•
EN/IEC 61000-6-2:2005 Electromagnetic compatibility (EMC) - Part 6-2: Generic standards - Immunity
for industrial environments
•
EN 61000-6-4:2007/A1:2011, IEC 61000-6-4:2006 Electromagnetic compatibility (EMC) - Part 6-4:
Generic standards - Emission standard for industrial environments
Enviromental conditions
Altitude up to 2000 m
•
Maximum relative humidity 95% non condensing
•
Rated pollution degree (evaluated for pollution degree 2 rating)
•
Protection
All PVE-EX actuators comply with protection class IP67 and IP69k according to EN60529. However, in
particularly exposed applications, protection in the form of shielding is recommended.
Specific conditions for safe use ("X"-mark)
Repairs of the flameproof joints must be made in compliance with the structural specifications provided
by the manufacturer. Repairs must not be made on basis of values specified in tables 1 and 2 of EN/IEC
60079-1.
Originally supplied "SD cable glands" may not provide sufficient clamping. User shall provide additional
clamping of the cable to ensure that pulling and twisting is not transmitted to the terminations.
Fasteners used for enclosure must be made from stainless steel grade A4 or stronger (Yield stress 210
MPa)
Warnings
Before implementing actuators in any application, read all warnings. Warnings are listed next to the most
relevant section and repeated in the chapter PVE-EX warnings on page 18.
Do not regard the warnings as a full list of potential risks. Depending on the application and use, other
potential risks can occur.
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).
