The equipment has been designed for a grade 3 contamination rating.
Appropriate measures should be taken to ensure that the inverter air su-
pply is dust free and of sufficient quality.
When operating, the inverters give off a slight buzzing sound.
Do not locate the inverters in an occupied room, or on lightweight
supports which could amplify this noise. The mounting surface must
be firm and adequate for the weight of the equipment.

system.
The system consists of 4 plates bolted to the four corners of the inverter's
base to secure the inverter to the concrete pad.

- Minimun distance between the center of thedrill on the concrete slab to
its borders of 3 in (76 mm).
- Diameter of the drill on the concrete slab to its borders of 0.31 in (8 mm).
- Minimun depth of thedrill on the concrete slab of 3 in (76 mm).
- Minimun thickness of the concrete slab of 4 in (102 mm).
- Torque of 14.75 lb-ft (20 Nm).
