I. Keep lift operator in constant attendance when-
ever compressor is suspended.
J. Set compressor down only on a level surface
capable of safely supporting at least its weight
and its loading unit.
K. When moving the compressor by forklift truck,
utilize fork pockets if provided. Otherwise, utilize
pallet if provided. If neither fork pockets or pallet
are provided, then make sure compressor is
secure and well balanced on forks before
attempting to raise or transport it any significant
distance.
L. Make sure forklift truck forks are fully engaged
and tipped back prior to lifting or transporting the
compressor.
M. Forklift no higher than necessary to clear obsta-
cles at floor level and transport and corner at
minimum practical speeds.
N. Make sure pallet-mounted compressors are
firmly bolted or otherwise secured to the pallet
prior to attempting to forklift or transport them.
NEVER attempt to forklift a compressor that is
not secured to its pallet, as uneven floors or sud-
den stops may cause the compressor to tumble
off, possibly causing serious injury or property
damage in the process.
1.10 ENTRAPMENT
A. If the compressor enclosure, if any, is large
enough to hold a man and if it is necessary to
enter it to perform service adjustments, inform
other personnel before doing so, or else secure
and tag the access door in the open position to
avoid the possibility of others closing and possi-
bly latching the door with personnel inside.
B. Make sure all personnel are out of compressor
before closing and latching enclosure doors.
1.11 SAFETY WARNINGS
The following special instructions apply to VSD
packages provided with electronic adjustable speed
motor drives. These cautions that apply to VSD
operation.
WARNING
Ground the unit following the instructions in this
manual. Ungrounded units may cause electric
shock and/or fire. The variable speed drive has a
large capacitive leakage current during operation,
which can cause enclosure parts to be above
ground potential. Proper grounding, as described
in this manual, is required. Failure 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 conditions. Failure to
observe this precaution could result in death or
severe injury.
WARNING
Refer all drive service to trained technicians. This
equipment should be installed, adjusted, and
serviced by qualified electrical maintenance
personnel familiar with the construction and
operation of this type of equipment and the
hazards involved and in accordance with
published service manuals. 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 terminals (-/+)
are live when the drive is connected to power,
even if the motor is not running. Contact with this
voltage is extremely dangerous and may cause
death or severe injury.
