7.0 INSTALLATION
The drive should be mounted on a smooth vertical surface capable of safely supporting the
unit without vibrating. The LCD display has an optimum field of view, this should be
considered when determining the mounting position.
Chassis models must be installed in an electrical enclosure which will provide complete
mechanical protection and maintain uniform internal temperature within the drive’s ambient
operating temperature rating. All drive models MUST be mounted in a vertical position for
proper heatsink cooling.
Maintain a minimum spacing around the drive of 2 inches for units rated 5 HP and below, 4
inches for units rated 7.5-25 HP, and 6 inches for units rated 30-60 HP.
Fans or blowers should be used to insure proper cooling in tight quarters. Do not mount
drives above other drives or heat producing equipment that would impede the cooling of the
drive. Note the ambient operating temperature ratings for each drive model.
If it is necessary to drill or cut the drive enclosure or panel, extreme care must be taken to
avoid damaging drive components or contaminating the drive with metal fragments (which
cause shorting of electrical circuits). Cover drive components with a clean cloth to keep out
metal chips and other debris. Use a vacuum cleaner to clean drive components after drilling,
even if chips do not appear to be present. Do not attempt to use positive air pressure to blow
chips out of drive, as this tends to lodge debris under electronic components. Contaminating
the drive with metal chips can cause drive failure and will void the warranty.
The AC400 Series is UL approved for solid state motor overload protection. Therefore, a
separate thermal overload relay is not required for single motor applications. In applications
where one drive is operating more than one motor, a separate thermal overload relay is
required for each motor per NEC.
Warning
Drives must not be installed where subjected to adverse environmental conditions!
Drives must not be installed where subjected to: combustible, oily, or hazardous
vapors or dust; excessive moisture or dirt; strong vibration; excessive ambient
temperatures. Consult Minarik for more information on the suitability of a drive to
a particular environment.
