1 Grounding requirements differ from country to country. Confirm the requirements of
your work environment prior to installation. For further information, please contact
your Pro-face distributor.
2 The front face of the LT unit is installed in a solid panel, and has been tested under
conditions equivalent to the standards listed in the specifications. The LT unit’s level of
resistance is equivalent to these standards; however, oils that should have no effect on
the LT can harm the unit — when vaporized oils are present, when low-viscosity cutting
oils are allowed to adhere to the unit for long periods of time, or if the protective sheet
on the front face of the LT peels off. These conditions can lead to the ingress of oil into
the LT, and alternate protective measures are recommended. Also, the presence of non-
approved oils may cause deformation or corrosion of the front panel’s plastic cover.
Therefore, prior to installing the LT, confirm the type of conditions that will be present in
the LT unit’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, replace the
installation gasket regularly.
