Installation
Environmental Considerations
If your EN Drive will be subjected to atmospheric contaminants such as
moisture, oils, conductive dust, chemical contaminants and metallic particles,
you must mount it vertically in a metal NEMA type 12 or equivalent enclosure
as a minimum.
If the ambient temperature inside the enclosure will exceed 104° F (40° C), you
must consider supplementary cooling.
CAUTION
Failure to maintain the ambient temperature within allowable
specifications will result in reduced product life and/or erratic or
dangerous operation.
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. Consult your enclosure manufacture for
application details.
Basic Installation Notes
You are required to follow all safety precautions during start-up such as
providing proper equipment grounding, correctly fused power and an effective
Emergency Stop circuit which can immediately remove power in the case of a
malfunction.
• To avoid problems associated with EMI (electromagnetic interference),
you should route high power lines (AC power and motor power) away
from low power lines (encoder feedback, serial communications, etc.).
• You should consider future troubleshooting and repair when installing
all wiring. All wiring should be either color coded and/or tagged with
industrial wire tabs.
• The minimum cable bend radius is ten times the cable outer diameter.
• Ground wires should not be shared with other equipment. Ensure that
metal to metal contact is made between the enclosure ground lug and
the metal enclosure.
• All inductive coils must be suppressed with appropriate devices, such as
diodes or RC networks.
