Product Dimensions
Refer to “Installation Drawings”, page 3-51 for further information.
Ventilation and Cooling Requirements
The drive must be able to dissipate the heat it generates during use. Therefore, mount the unit vertically so that a free flow of cool air can pass through
the drive. For 7.5 through 60 HP rated models, allow a minimum of 4"(100mm) of clear space above and below the drive to ensure adequate free air
flow. Leave 6"(150mm) clearance above and below models rated 75 through 100 HP.
When mounting drives one above the other, allow at least 7"(175mm) between the top and bottom drives. Each drive requires the same clearance as
required when used singly. When mounting drives next to each other, leave 1½"(38mm) left to right between units.
Make sure the unit is not mounted on or next to equipment that will cause the drive to overheat. Normal maximum ambient operating temperature is
113°F (45°C) up to 150 HP and 104°F (40°C) for larger drives. Above this limit, the controller must be derated. The maximum ambient operating
temperature is 131°F (55°C).
The table below lists the heat dissipation in Watts of DC590+ DRV Digital drives through 500 horsepower (at 500 VDC).
Motor Rating HP @ 500V Motor FLC (A) Total Watts Motor Rating HP @ 500V Motor FLC (A) Total Watts

50 90 291 400 648 1722
Note: Total Watts for 200 to 500 horsepower models can be reduced by 80 percent if the exhaust duct is used to vent the drive outside the enclosure.
