INSTALLATION

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 Lenze AC Tech for more information on the suitability of a
drive to a particular environment .
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 that 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 as follows:
All drive models MUST be mounted in a vertical position for proper heatsink cooling .
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 MC3000 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 .
