2.1
Installation
The following installation requirements, methods and procedures are provided to assure
reliable and trouble free installation of your Emerson MC LX Drive.
The methods and procedures are outlined on the following pages and include site
requirements, safety considerations, power and fusing requirements, wire and
transformer sizing, noise suppression, and I/O wiring.
2.2
Safety Considerations
The installer/user is responsible for incorporating appropriate safety features into the
equipment to prevent injury to personnel or damage to equipment.
The installer/user has the responsibility to comply with the safety requirements of the
system. This includes installing the system with an appropriate master interlock switch
for emergency shut down and using the proper wire and transformer sizes (if necessary)
to fit the system. This section will provide you with the information to complete a trouble
free installation.
The user is responsible for providing emergency interlock switches that will
remove AC power from the system any time the equipment is not running, or
when the emergency stop is activated. This is to eliminate the possibility of
electrocution or unwanted movement of the motor. The safety ground
connections should only be disconnected for servicing and only after all AC
power has been removed.
2.3
Selecting an Enclosure
The LX drive is designed for the industrial environment. However, no sophisticated
electronic system can tolerate certain atmospheric contaminants such as moisture, oils,
conductive dust, chemical contaminates and metallic particles. Therefore, if the drive is
going to be subjected to this type of environment it must be mounted vertically in a
NEMA type 12 enclosure.
Proper ventilation and filtering must also be provided. If the equipment environment is
above 50° C, cooling is mandatory. The amount of cooling depends on the size of the
enclosure, the thermal transfer of the enclosure to the ambient air and the amount of
power being dissipated inside the enclosure. Your enclosure supplier can assist you in
properly selecting an enclosure for your application.
