SUPERVISOR CONTROLLER™ USER MANUAL
VARIABLE SPEED DRIVE
6.1 SAFETY
The following special instructions apply to VSD
packages provided with electronic adjustable speed
motor drives. These are in addition to other warnings
and cautions.
WARNING
Ground the unit following the instructions
in this manual. Ungrounded units may
cause electric shock and/or fire. The vari-
able speed drive has a large capacitive leak-
age current during operation, which can
cause enclosure parts to be above ground
potential. Proper grounding, as described in
this manual, is required. Fai ure to observe
this precaution could result in death or
severe injury.
WARNING
Before applying power to the variable speed
drive, make sure that the front and cable
covers are closed and fastened to prevent
exposure to potential electrical fault condi-
tions. Failure to observe this precaution
could result in death or severe injury.
WARNING
Refer all drive service to trained techni-
cians. This equipment should be installed,
adjusted, and serviced by qualified electri-
cal maintenance personnel familiar with the
construction and operation of this type of
equipment and the hazards involved and in
accordance with published service manu-
als. Failure to observe this precaution could
result in death or severe injury.
WARNING
Line terminals (L1, L2, L3), motor terminals
(U, V, W) and the DClink/brake resistor ter-
minals (-/+) are live when the drive is con-
nected to power, even if the motor is not
running. Contact with this voltage is
extremely dangerous and may cause death
or severe injury.
