Be aware of the following items when building the LT into an end-use product:
• The LT unit’s rear face is not approved as an enclosure. When building the LT unit into an end-use product, be sure to
use an enclosure that satisfies standards as the end-use product’s overall enclosure.
• The LT unit must be used indoors only.
• Install and operate the LT with its front panel facing outwards.
• If the LT is mounted so as to cool itself naturally, be sure to install it in a vertical panel. Also, it’s recommended that
the LT should be mounted at least 100 mm away from any other adjacent structures or machine parts. The temperature
must be checked on the final product in which the LT is installed.
• For use on a flat surface of a Type 4X (Indoor Use Only) and/or Type 13 Enclosure.
