Motor and Equipment Safety
CAUTION
Do not perform any meggar or voltage withstand tests on
any part of the drive or its components. Improper testing may
result in damage.
CAUTION
Prior to any tests or measurements of the motor or the
motor cable, disconnect the motor cable at the drive output
terminals (U, V, W) to avoid damaging the drive during motor
or cable testing.
CAUTION
Do not touch any components on the circuit boards. Static
voltage discharge may damage the components.
CAUTION
Before starting the motor, check that the motor is mounted
properly and aligned with the driven equipment. Ensure that
starting the motor will not cause personal injury or damage
equipment connected to the motor.
CAUTION
Set the maximum motor speed (frequency) in the drive
according to the requirements of the motor and the
equipment connected to it. Incorrect maximum frequency
settings can cause motor or equipment damage and personal
injury.
CAUTION
Before reversing the motor rotation direction, ensure that
this will not cause personal injury or equipment damage.
CAUTION
Make sure that no power correction capacitors are
connected to the drive output or the motor terminals to
prevent drive malfunction and potential damage.
CAUTION
Make sure that the drive output terminals (U, V, W) are not
connected to the utility line power as severe damage to the
drive may occur.
CAUTION
When the control terminals of two or more drive units are
connected in parallel, the auxiliary voltage for these control
connections must be taken from a single source which can
either be one of the units or an external supply.
CAUTION
The drive will start up automatically after an input voltage
interruption if the external run command is on.
CAUTION
Do not control the motor with the disconnecting device
(disconnecting means); instead, use the control panel start
and stop keys and, or commands via the I/O board of the
drive. The maximum allowed number of charging cycles of
the DC capacitors (i.e. power-ups by applying power) is five in
ten minutes.
CAUTION
Improper drive operation:
●
If the drive is not turned on for a long period, the
performance of its electrolytic capacitors will be reduced.
●
If it is stopped for a prolonged period, turn the drive on at
least every six months for at least 5 hours to restore the
performance of the capacitors, and then check its
operation. It is recommended that the drive is not
connected directly to the line voltage. The voltage should
be increased gradually using an adjustable AC source.
Failure to follow these instructions can result in injury
and / or equipment damage.
For more technical information, contact the factory or your
local Eaton sales representative.
