The 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. Like-
wise, 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 se-
cure EMC of the whole facility (device).
According to Norm EN 61326-1: 2006 (chart 2) DC supply connections to the encoder are treated as
input/ output signals lines. For cable lengths longer than 30 m and outdoor applications additional
measures must be implemented in order to comply with CE
In electrostatic threatened areas please take care for neat ESD - protection of plug and connecting
cable during installation work.
The connecting cable is only suitable for fixed installation (no haulage operating).
The facility installer is responsible for cable selection with consideration of EX - rules.
The gap width are smaller than specified in the standard. Moreover some gap lengths are exceeding
tabular values. Therefore repairs according to tabular values are not allowed. A general overhauling
is only allowed by the manufacturer Hengstler.
The pressure - proof encapsulated encoder housing must not be opened!
For use in class II circuits only
Explosion protection classification
Hengstler explosion - proof shaft encoders are classified according to
