4 INSTALLATION AND WIRING
The Q170ENC contains a glass disk and precision mechanism. Take care when handling it. The
encoder performance may deteriorate if it is dropped or subjected to shocks or vibration exceeding the
prescribed limits.
Do not connect the shaft of Q170ENC directly to machine side rotary shaft. Always after connecting
the shaft of Q170ENC to another bearing once, connect the shaft through a flexible coupling.
Never hit the end of the Q170ENC coupling shaft with a hammer when connecting the coupling to it.
The large loads applied to Q170ENC will damage it.
The Q170ENC uses optical parts. Install it in an atmosphere where there are extremely few water
drops and little oil and dust.
In any place where the Q170ENC is exposed to water and/or oil, provide protection from oil and water,
e.g. install a cover. In addition, run the cable downward to prevent oil and/or water from running on the
cable into the Q170ENC. When it is inevitable to install the Q170ENC vertically or obliquely, trap for
the cable.
Use the Q170ENC within the specified temperature range (-5°C to 55°C (23 to 131°F) ).
