The encoders of the 7014SIL model series have been designed, developed and manufactured in
compliance with the relevant safety requirements of the following industrial standards:
Protection class: DIN EN 60529 IP6X: 2000
Climate testing: DIN EN 60068-2-3: 1986
Emission of interferences: DIN EN 61000-6-3 and DIN EN 61000-6-4: 2003
Shock resistance: DIN EN 60068-2-27: 1995
Vibration resistance: DIN EN 60068-2-6: 1996
Manufactured according to: DIN EN 61010-1 protection class III: 2002
To prevent dangerous structure-borne currents, the encoders must be operated with safety extra-low
voltages (SELV) and be located in an area with equipotential bonding.
Use an external fuse for protection (see the electrical data).
Fields of application: industrial processes and controls.
Over-voltages at the terminals of the device must be kept within the limits of overvoltage category II.
Avoid shocks to the housing – especially to the encoder shaft – and axial and radial overload to the
encoder shaft. Maximum accuracy and durability of the encoders are only granted when using à suitable
coupling.
The high-level EMC characteristics are only valid in connection with cables and connectors supplied
as a standard. When using shielded cables, the shield must be connected to ground over a large
area. Also the voltage supply cables should be entirely shielded. If this is not possible, appropriate filtering
measures must be taken. The installation environment and the wiring have a significant influence
on the EMC of the encoder. Therefore, the installer must secure the EMC of the whole plant
(device).
Voltage peaks on the supply cable are to be limited to max. 1000 V by the upstream power supply. In
electrostatically critical areas, a good ESD protection is to be provided during installation work for the
connectors and the cable to be connected.
The connection cable is suitable only for fixed installation (no mobile operation). The choice of the
cable, in compliance with the Ex regulations, is the responsibility of the plant builder. The flameproof
encoder housing may in no case be opened.
The encoders of the 7014SIL model series are manufactured in compliance with Directive 94/9/EC.
The product is intended exclusively for integration in or mounting on suitable plants.
