Mounting Guidelines for Lutron DIN Rail Products
■Choose a high-quality enclosure manufacturer.
■In North America, always use an enclosure evaluated and marked by a Nationally Recognized Testing Laboratory (NRTL).
■In North America, it is strongly recommended that the enclosure and module combinations be submitted to the Authority Having Jurisdiction (AHJ) for review prior to installation. The AHJ may require inspection of the finished installation by a NRTL.
■Determine what the power dissipation is for all the DIN components (power modules, breakers, power supplies, etc.).
■Determine the enclosure size based on total heat dissipation requirements and module mounting length requirements. Mount all products in an IP20 (minimum) or NEMA Type 1 (minimum) enclosure, and be sure to choose the correct IP rating that complies with local codes for your installation.
■Consult with the enclosure manufacturer to determine the amount of venting required. Some enclosure manufacturers provide design software to aid in this process.
■To achieve best performance, Lutron recommends using ventilated enclosures with natural convection cooling where possible.
■ Mount DIN power modules with arrows facing up to ensure adequate cooling.
■Install heavily loaded units near the bottom of a non-ventilated enclosure or near the exhaust of a ventilated enclosure.
■Where possible, have the heat sink on phase-adaptive modules (LQSE-4A-D / LQSE-4A-120-D / LQSE-4A5-120-D / LQSE-4A5-230-D / QSNE-4A-D / QSNE-4A5-230-D) exposed through the front cover.
■ Ensure there is code-compliant separation between line-voltage and low-voltage wiring.
■ DO NOT place module panels above other sources of heat.
