Designing the Installation of the Scale Unit
2.2.1 Scale Main Unit Mounting Directions and Cover Preparations
When installing this product, be sure to install the cover so that cutting oil, chips, etc. do not splatter
onto the scale main unit.
Only the dust proof-rubber lips are used to protect the opening side of the scale main unit from the in-
trusion of foreign objects. Therefore, when deciding the mounting direction of the scale main unit, give
consideration to the splattering directions of the cutting oil, chips, etc., since the opening side poses a
greater hazard of foreign matter intrusion than the other sides.
