Safety
Definitions and Symbols
WARNING
This symbol indicates high voltage. It calls your attention to items
or operations that could be dangerous to you and other persons
operating this equipment. Read the message and follow the
instructions carefully.
This symbol is the “Safety Alert Symbol.” It occurs with either of
two signal words: CAUTION or WARNING, as described below.
WARNING

product. The situation described in the CAUTION may, if not
avoided, lead to serious results. Important safety measures are
described in CAUTION (as well as WARNING).
Hazardous High Voltage
WARNING
Motor control equipment and electronic controllers are connected
to hazardous line voltages. When servicing drives and electronic
controllers, there may be exposed components with housings or
protrusions at or above line potential. Extreme care should be taken
to protect against shock.
Stand on an insulating pad and make it a habit to use only one
hand when checking components. Always work with another
person in case an emergency occurs. Disconnect power before
checking controllers or performing maintenance. Be sure
equipment is properly grounded. Wear safety glasses whenever
working on electronic controllers or rotating machinery.
WARNING
After disconnecting the utility, wait until the unit cooling fan stops
and the indicators on the control panel are extinguished (if no
keypad is present, check the indicators in the cover). Wait five more
minutes before doing any work on the connections. Do not open
the cover before this time has run out.

Chapter 1 — General
The NEMA Type 12 Kit is used to convert a Cutler-Hammer
®
9000X drive by Eaton Electrical
®
from a NEMA Type 1 to a NEMA Type 12 enclosure. A NEMA Type 12 enclosure may be
necessary when the adjustable frequency drive is used in ambient conditions that may
contain moisture or dust.
According to standard IEC 60529 (EN 60 529), the NEMA Type 12 adjustable frequency drives
enclosure provides protection against dust and water sprayed from all directions. Limited
ingress of both is permitted.
Note: A NEMA Type 12 enclosure does not protect the adjustable frequency drive against
strong jets of water or against the effects of immersion.
