Structure *1
*1 The front face of the LT unit, installed in a solid panel, has been tested using
conditions equivalent to the standards shown in the specification. Even though the
LT unit’s level of resistance is equivalent to these standards, oils that should have no
effect on the LT can possibly harm the unit. This can occur in areas where either va-
porized oils are present, or where low viscosity cutting oils are allowed to adhere to
the unit for long periods of time. If the LT’s front face protection sheet becomes
peeled off, these conditions can lead to the ingress of oil into the LT and separate
protection measures are suggested.
Also, if non-approved oils are present, it may cause deformation or corrosion of the
front panel’s plastic cover. Therefore, prior to installing the LT be sure to confirm the
type of conditions that will be present in the LT’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 guaran-
teed. To maintain the original protection level, be sure to replace the installation gas-
ket regularly.
