Never hit the end of
coupling to it.
The large loads applied to MR-HENC/Q170ENC will damage it.
The MR-HENC/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 MR-HENC/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
