Installation instructions
Incremental Shaft Encoder Type RI 42
Item No. 2 521 251, Edition 3 161105 HOR
Introduction
These installation instructions are provided for the connection and starting
procedure of your shaft encoders.
Safety and Operating Instructions
• The incremental shaft encoders of the type RI 42 model series are quality
products manufactured in accordance with established electrical engineering
standards. The units have been delivered from the factory in perfect confor-
mance to safety regulations.
To maintain this condition and to ensure trouble-free operation, please
observe the technical specifications of this document.
• Installation and mounting may only be performed by an electrotechnical
expert!
• The units may only be operated within the limits specified by the technical data.
• Maximum operating voltages must not be exceeded!
The units are designed complying with VDE 0160, protection class III.
To prevent dangerous structure-borne currents, the equipment has to be run
on safety extra-low voltage (SELV) and must be in an area of equipotential
bonding.
• Application: Industrial processes and control systems.
Overvoltage at the connecting terminals must be limited to the values within
overvoltage category II.
• Please avoid shocks to the housing – especially to the encoder shaft – and
axial or radial overload to the encoder shaft.
• Maximum accuracy and durability of our shaft encoders is only granted
when using suitable couplings.
• The high-quality EMC-specifications are only valid together with standard-
type cables and plugs. When using screened cables, the screen must broadly
be connected with ground on both ends. Likewise, the voltage-supply cables
should entirely be screened. If this is not possible you will have to take
appropriate filtering measures.
• Installation environment and wiring are influential on the encoder's EMC:
Thus the installer must secure EMC of the whole facility (device).
• Transient peaks on the power supply leads are to be limited by the pre-
connected power unit to a maximum of 1000 V.
• In electrostaticly threatened areas please take care for neat ESD-protection
of plug and connecting cable during installation work.
• Specified maximum shaft loads are only given under restrictions:
10
– Full bearing life of 1 x 10 revolutions (typ.) will be reached at 35% of full
rated shaft load
8
– a bearing life of 1 x 10 revolutions (typ.) will be reached at 100% of full
rated shaft load.
• For use in class II circuits only
