CHAPTER 2: INSTALLATION 12-5-97 PAGE 14
2.4.4
WARNING – STRAIN HAZARD:
Improper lifting practices can cause
serious or fatal injury. Lift only with adequate equipment and trained personnel.
2.4.5
WARNING – ELECTRICAL SHOCK HAZARD:
All motor bases and
equipment enclosure housings should be grounded in accordance with the National
Electric Code or equivalent.
2.4.6
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.
2.4.7
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.
2.4.8
WARNING –
Replace all covers before applying power to the Drive. Failure to
do so may result in death or serious injury.
2.4.9
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.
2.4.10 CAUTION:
Do not connect power supply to the output terminals (U,V,W).
Connect power supply only to the power terminals (L1, L2, L3).
2.4.11 CAUTION:
Do not connect a power supply to the control circuit terminals
(except 30A, B, C, maximum rating 250 volts, 0.3A ac/dc).
2.4.12 CAUTION:
For RUN and STOP, use the FWD-CM (forward) and REV-CM
(reverse) terminals. Do not use a contactor (ON/OFF) installed on the line side of the Drive
for RUN and STOP.
2.4.13 CAUTION:
Do not use a switch on the output side of the Drive for ON/OFF
operation.
2.4.14 CAUTION:
Do not connect filter capacitors on the output side of the Drive.
2.4.15 CAUTION:
Do not operate the Drive without the ground wire connected. The
motor chassis should be grounded to earth through a ground lead separate from all other
equipment ground leads to prevent noise coupling. The grounding connector shall be
sized in accordance with the NEC or Canadian Electrical Code. The connection shall be
made by a UL listed or CSA certified closed-loop terminal connector sized for the wire
gauge involved. The connector is to be fixed using the crimp tool specified by the
connector manufacturer.
2.4.16 CAUTION:
Do not perform a megger test between the Drive terminals or on the
control circuit terminals.
