ailure to observe these precautions may damage the unit and void the Warranty
!
• Do not mount the dynamic brake unit near heat-radiating elements or in direct sunlight.
• Do not install the dynamic brake unit in a place subjected to high temperatures, high humidity,
excessive vibration, corrosive gasses or liquids, or airborne dust or metallic particles.
• Mount the dynamic brake unit vertically and do not restrict the air flow to the heat sink fins.
