9. Maintenance
If the Mux is mounted in a cabinet, door should remain closed as often as possible. A lock
should be used if necessary.
The ambient temperature of the Mux should be checked in the operating environment at its
highest temperature. The temperature should not exceed 70ºC. Doing so will not damage the
electronics but may affect the temperature measurement accuracy. If the temperature exceeds
80ºC, failure is possible. Use radiation shielding or the optional purge air to keep the
electronics cool.
Periodically check Mux for signs of deposition of water, oil, dirt, etc. If necessary, clean it by
disconnecting the DC power and wiping it down with a soft, slightly damp cloth.
If the Mux is mounted in a cabinet, check the inside of the cabinet for dirt, oil, water, etc. If
discovered, take appropriate action to prevent damage to the electronic components.
