Introduction

These installation instructions are provided for the connection and starting
procedure of your shaft encoder.
You will get further information from our Shaft Encoders Catalogue or on
request.

Safety and Operating Instructions

• The incremental shaft encoders of the type RI 38 model series are quality
products manufactured in accordance with established electrical engineering
standards.
The units have been delivered from the factory in perfect conformance to
safety regulations.
To maintain this condition and to ensure trouble-free operation, please ob-
serve 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.
• Fields of application: industrial processes and controls.
Overvoltage at the connecting terminals must be limited to overvoltage-
class-II values.
• 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.
