6. How to Install
6.3.3. Installation on the Wall - IP21 (NEMA 1) and IP54 (NEMA 12) Units
This only applies for D1 and D2 enclosures.
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 secure the frequency converter
against the wall.

6.3.4. Gland/Conduit Entry - IP21 (NEMA 1) and IP54 (NEMA12)
Cables are connected through the gland plate from the bottom. Remove
the plate and plan where to place the entry for the glands or conduits.
Prepare holes in the marked area on the drawing.
The gland plate must be fitted to the frequency converter to ensure the
specified protection degree, as well as ensuring proper cooling of the unit.
If the gland plate is not mounted, it may trip the unit.
