How to Prepare for ASR0404021-316 Installation

This guide outlines essential safety and environmental considerations for preparing the installation site of the ASR0404021-316, focusing on mounting surface requirements and enclosure integrity.

Estimated time: 15m

Supplies needed:

Floor plate (1.43 mm galvanized or 1.6 mm uncoated steel)

  1. Evaluate Mounting Surface

    Before mounting the ASR0404021-316, evaluate the installation surface. If mounting on or over a combustible surface, a protective floor plate is mandatory.

  2. Install Protective Floor Plate

    If a combustible surface is present, install a floor plate made of at least 1.43 mm galvanized steel or 1.6 mm uncoated steel. Ensure the plate extends a minimum of 150 mm beyond the equipment on all sides.

  3. Ensure Enclosure Environmental Integrity

    When customizing the enclosure or closing any openings, use only devices that possess the same environmental ratings as the ASR0404021-316 to preserve the enclosure's environmental integrity.
