3.3.7 Installation on the Wall - IP21 (NEMA
1) and IP54 (NEMA 12) Units
This only applies to enclosure types D1 and D2. It must be
considered where to install the unit.
Take the relevant points into consideration before
selecting the final installation site:
•
Free space for cooling
•
Access to open the door
•
Cable entry from the bottom
Mark the mounting holes carefully using the mounting
template on the wall and drill the holes as indicated.
Ensure proper distance to the floor and the ceiling for
cooling. A minimum of 225 mm (8.9 inch) below the
frequency converter is needed. Mount the bolts at the
bottom and lift the frequency converter up on the bolts.
Tilt the frequency converter against the wall and mount
the upper bolts. Tighten all 4 bolts to secure the frequency
converter against the wall.
