Environmental - Digital Electronics Pro-face GP-377 Series User Manual

(from previous page)
*1 The front face of the GP unit, installed in a solid panel, has been tested using condi-
tions equivalent to the standard shown in the specification . Even though the GP
unit's level of resistance is equivalent to the standard, oils that should have no effect
on the GP can possibly harm the unit. This can occur in areas where either vaporized
oils are present, or where low viscosity cutting oils are allowed to adhere to the unit
for long periods of time. If the GP's front face protection sheet becomes peeled off,
these conditions can lead to the ingress of oil into the GP and separate protection
measures are suggested. Also, if non-approved oils are present, it may cause deforma-
tion or corrosion of the front panel's plastic cover. Therefore, prior to installing the
GP be sure to confirm the type of conditions that will be present in the GP's operating
environment.
If the installation gasket is used for a long period of time, or if the unit and its gasket
are removed from the panel, the original level of the protection cannot be guaranteed.
To maintain the original protection level, you need to replace the installation gasket
regularly.
