WARNING!
Operation of this drive requires detailed installation and operation
instructions provided in the hardware and software manuals. The manuals are
provided in electric format in the drive package or on the Internet. Keep the
manuals with the drive at all times. Hard copies of the manuals can be ordered through the
manufacturer.
•
Make sure that the drive type designation label includes the applicable marking.
•
DANGER - Risk of electric shock.
After disconnecting the input power, always wait
for 5 minutes to let the intermediate circuit capacitors discharge before you start
working on the drive, motor or motor cable.
•
The drive is to be used in a heated, indoor controlled environment. The drive must be
installed in clean air according to the enclosure classification. Cooling air must be
clean, free from corrosive materials and electrically conductive dust.
•
The maximum surrounding air temperature is 40 °C at rated output current. The output
current is derated for 40…55 °C.
•
The drive is suitable for use in a circuit capable of delivering not more than 100000 rms
symmetrical amperes, 480 V maximum when protected by the UL fuses given in table
on page
. The ampere rating is based on tests done according to the
appropriate UL standard.
•
The cables located within the motor circuit must be rated for at least 75 °C in UL-
compliant installations.
•
The input cable must be protected with fuses. The fuses must provide branch circuit
protection in accordance with the national regulations (National Electrical Code (NEC)
or Canadian Electrical code). Obey also any other applicable local or provincial codes.
Note:
Circuit breakers must not be used without fuses in UL installation. For suitable
circuit breakers, see the hardware manual.
WARNING!
The opening of the branch-circuit protective device may be an
indication that a fault current has been interrupted. To reduce the risk of fire or
electric shock, current-carrying parts and other components of the device
should be examined and replaced if damaged.
•
The drive provides motor overload protection. For adjustments, see the firmware
manual.
•
The drive overvoltage category according to IEC 60664-1 is III.
