How to Prepare for SSTB202012-316 Installation

This guide outlines critical safety preparations required before installing the SSTB202012-316 device, focusing on proper mounting surface preparation and maintaining enclosure integrity.

Estimated time: 5m

Supplies needed:

Floor plate (1.43 mm galvanized or 1.6 mm uncoated steel), Devices with appropriate environmental ratings

  1. Review Mounting Surface Safety

    Carefully assess the intended mounting surface for the SSTB202012-316. If the device is to be mounted on or over a combustible surface, specific precautions are required to prevent fire hazards. Proceed to the next step if this condition applies.

  2. Install Protective Floor Plate

    When mounting the SSTB202012-316 on or over a combustible surface, install a protective floor plate. This plate must be at least 1.43 mm galvanized steel or 1.6 mm uncoated steel, and it must extend at least 150 mm beyond the equipment on all sides to provide adequate protection.

  3. Maintain Enclosure Environmental Integrity

    During the installation process, especially when customizing the enclosure or closing openings, ensure that all devices used have the same environmental ratings as the SSTB202012-316 enclosure. This is crucial to maintain the specified environmental integrity of the enclosure and protect the equipment from external elements.
