What the Kit Does
This kit adapts an Altivar 71 drive for mounting in an enclosure with a wall thickness of 1.5 to 3 mm. It is specified for enclosures with heat-treated epoxy paintwork (fine or medium texture) or those made of stainless or paint-finished smooth steel. The included thermal liner and heatsink manage the drive's thermal dissipation when enclosed, which is the critical selection parameter: without this kit, the drive cannot be sealed in a dust- and damp-proof cabinet without exceeding its thermal limits.
