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 MC1000 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 AC
TECHNOLOGY FOR MORE INFORMATION ON THE SUITABILITY OF
A DRIVE TO A PARTICULAR ENVIRONMENT.
