Warnings
Note:
– After installation and exchange, an acceptance test according to the machine instructions
must be performed.
– Mounting and commissioning is to be executed by a specialist in electricity and precision mechanics
under compliance with local safety regulations.
– Do not engage or disengage any connections while under power.
– In addition to this, the machine manufacturer or designer himself must define the other data required
for final assembly (e.g. anti-rotation lock for screws required or not) for the respective application.
– Information on mounting (e.g. optional checking of the shaft connection) must be specified by the
machine manufacturer or designer.
– Encoders that have contributed to the failure of a safety function in the application must be returned
to HEIDENHAIN Traunreut, together with the fasteners (screws).
– EnDat 22 cable assemblies from HEIDENHAIN must be used.
– Ripple currents through the ball bearings of the encoder are not permissible.
– Original packaging must be used for transport and storage. Storage temperature –30 ... 65 °C.
– Do not drop the encoder or subject it to major vibration; avoid impact or shock.
– Avoid direct contact of aggressive media with the encoder and connector.
– Do not clean the encoder with organic solvents like thinners, alcohol or benzene.
– Prevent the encoder from getting into contact with small chips, sharp objects etc. because they can
destroy the sealing system.
– A PELV* power supply (power pack) with overvoltage protection, and overcurrent protection
if necessary, must be used.
