3.3.7 Installation on the Wall - IP21 (NEMA 1) and IP54 (NEMA 12) Units
This only applies to frame sizes D1 and D2 . It must be considered
where to install the unit.
Take the relevant points into consideration before you select
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 four bolts to se-
cure the frequency converter against the wall.
