6.1.4 Rotating the connector for 1FK7xxx5 and 1FK7xxx-7
Power connectors and signal connectors can be rotated to a limited extent. A suitable socket
connector can be used to rotate the angle plug. Make sure that the socket connector is
completely secure to avoid damaging the pin contacts. For encoders with integrated Sensor
Modules (DQI) the cable outlet towards the top is fixed and cannot be changed.
NOTICE
Rotating the connectors
 It is not permissible that the specified rotation range is exceeded.
 In order to guarantee the degree of protection, max. 10 revolutions are permissible.
 Connectors should be rotated using the matching mating connector located on the
connector thread. Only rotate Sensor Modules by hand. The use of pipe wrenches,
hammers, or similar is not permitted.
