Checking if the Doors are Firmly Closed
• The YASNAC XRC has a fully sealed construction, designed to keep external air contain-
ing oil mist out of the XRC.
Be sure to keep the XRC doors fully closed at all times, even when the controller is not
operating.
• Open or close the two locks in each door with the minus driver when opening or closing
the doors for maintenance after the main power is turned off. (CW:Open, CCW:Close)
Make sure push the door closed and turn the door lock with the driver. When the door is
closed, turn the door lock until the door clicks.

Checking for Gaps or Damage in the Sealed Con-
struction Section
• Open the door and check that the seal around the door is undamaged.
• Check that the inside of the XRC is not excessively dirty. If it is dirty, determine the cause,
take measures to correct the problem and immediately clean up the dirt.
• Fully close each door lock and check that no excessive gaps exist around the edge of the
door.
