Section 1: Safety Precautions
WARNING - MECHANICAL MOTION HAZARD:
Drive systems cause mechanical motion. It is the responsi-
bility of the user to insure that any such motion does not
result in an unsafe condition. Factory provided interlocks
and operating limits should not be bypassed or modified.
WARNING - ELECTRICAL SHOCK AND BURN
HAZARD:
When using instruments such as oscilloscopes to work on
live equipment, the oscilloscope’s chassis should be
grounded and a differential amplifier input should be used.
Care should be used in the selection of probes and leads
and in the adjustment of the oscilloscope so that accurate
readings may be made. See instrument manufacturer’s
instruction book for proper operation and adjustments to
the instrument.
WARNING - FIRE AND EXPLOSION HAZARD:
Fires or explosions might result from mounting drives in
hazardous areas such as locations where flammable or
combustible vapors or dusts are present. Drives should be
installed away from hazardous areas, even if used with
motors suitable for use in these locations.
WARNING - STRAIN HAZARD:
Improper lifting practices can cause serious or fatal injury.
Lift only with adequate equipment and trained personnel.
WARNING - ELECTRICAL SHOCK HAZARD:
All motor bases and equipment enclosure housings should
be grounded in accordance with the National Electric Code
or equivalent.
WARNING - MOTOR OVERSPEED HAZARD:
With 400 Hz drive output possible, the drive will allow the
motor to run up to 6 - 7 times its base speed. Never
operate the motor above its top mechanical speed or a
catastrophic failure may occur.
Any applications requiring operation above
120 Hz must be approved by the Company.
WARNING -
Before disassembling, disconnect and lock out power from
the drive. Failure to disconnect power may result in death
or serious injury. A bus charge light provides visual
indication that bus voltage is present; verify the bus voltage
level by measuring the voltage between power terminals
P(+) and N(-) using an analog meter. Do not attempt to
service the drive until the charge indicator has extinguished
and the bus voltage has discharged to zero volts.
WARNING -
Replace all covers before applying power to the drive.
Failure to do so may result in death or serious injury.
CAUTION:
Do not connect power supply voltage that exceeds the
standard specification voltage fluctuation permissible. If
excessive voltage is applied to the drive, damage to the
internal components will result.
CAUTION:
Do not connect power supply to the output terminals (U, V,
W). Connect power supply only to the power terminals (L1,
L2, L3).
CAUTION:
Even though the main AF-300E$ power has been discon-
nected it may still receive electrical energy from more than
one source. If external power is applied to the control
terminals 30A, B & C and AX1 and AX2 as well as any
option card control input terminal points (if installed in the
drive), and if the independent power source is activated
separately from the AF-300E$'s main input power, failure to
to diconnect this external power source may result in death
or serious injury. This external power must be removed
prior to any work being performed on the drive.
WARNING: this equipment may receive electrical
energy from more than one source. Additional
disconnects are located outside this cabinet. Open all
associated disconnects before servicing equipment.
Refer to equipment diagrams.
