CAUTION
•
Observe the applicable professional association safety and accident regulations
for your country.
•
Switch off the voltage to all devices/systems affected by the mounting/installation.
•
Never establish or disconnect electrical connections to the encoder with the volt‐
age switched on as this can otherwise lead to a device defect.
•
Always prevent impacts and shocks to the encoder shaft. This can lead to bearing
defects.
•
For a proper functioning of the encoder, ensure that an EMC-suitable shielding
connection (application of the shielding on both sides) occurs!
•
This product is not designed for helping in ensuring the safety of persons either
directly or indirectly. Do not use it for such purposes.
•
Shielding must be properly connected.
•
Connect the encoder cable shield to the chassis ground.
•
First connect the US and GND correctly first before connecting the signal wires (A,
B, Z, A¯, B¯ and Z¯). The short circuit protection is only valid if the US and GND are
connected correctly.
•
Ensure physical separations between encoder cable and other power cables/tran‐
sient sources. Where possible, route them perpendicular to each other.
•
Insulate unused wires individually.
•
Allow water, oil or liquid to enter the encoder.
•
Subject the encoder to excessive force, impacts or knocks especially on the shaft
area.
•
Bend the cables excessively, especially near the connector or cable outlet.
•
(Recommended) extend the cable length beyond 10 meters
•
Apply voltages beyond the stipulated range.
TTL = 4.5 V DC ... 5.5 V DC
HTL and Open collector = 10 V DC ... 27 V DC
