1.7.1. Floor-Mounting (all enclosures)

Floor-mounting is the standard method of installing all 3PH ATevo enclosure styles. When floor-mounting ATevo, consider the following:

1. Refer to table below for external NEMA Type-1 outline drawing, overall dimensions, mounting hole pattern, and hardware mounting specs.
2. Be conscious of planned ac input and dc output wiring to the ATevo selecting conduit entrances carefully.
3. Location requirements:
   1. Free of drips and splatter. If falling particles and liquids are a problem, install a NEMA Type-2 drip shield accessory.
   2. Between 0 and 122 °F / -18 and 50 °C, with relative humidity between 0% and 95% non-condensing.
   3. Must be free of flammable or explosive materials.
4. Maintain at least 6in /152mm of free air on all vented surfaces for cooling.
5. Allow 36in /914mm front clearance for operation and maintenance.

PROCEDURE

1. Install four anchor bolts (not supplied with unit) into the floor.
2. Refer to table below for anchor bolt size and mounting dimensions.
3. Carefully lift the ATevo above the anchor bolts, guide the enclosure onto the floor bolt pattern and lower it into place.
4. Add appropriate mounting hardware to the anchor bolts and tighten securely.
