Motor And Equipment Safety - Eaton PowerXL DG1-323D7FB-C21C Installation Manual

Debounced inputs may not be used in the safety circuit
diagram. A changeover between the drive and the input
supply must take place in a voltage-free state.
Debounced inputs may not be used in the safety circuit
diagram. Fire hazard!
Only use cables, protective switches, and contactors that
feature the indicated permissible nominal current value.
Before connecting the drive to AC mains make sure that the
EMC protection class settings of the drive are appropriately
made according to instructions in this manual.
If the drive is to be used in a floating distribution network,
●
remove screws at MOV and EMC. See "Installation in
Corner-Grounded Network" on Page 43 and "Installation in
IT System" on Page 43 respectively.
Disconnect the internal EMC filter when installing the drive
●
on an IT system (an ungrounded power system or a
high-resistance-grounded [over 30 ohm] power system),
otherwise the system will be connected to ground
potential through the EMC filter capacitors. This may
cause danger, or damage the drive.
Disconnect the internal EMC filter when installing the drive
●
on a corner grounded TN system, otherwise the drive will
be damaged.
Note: When the internal EMC filter is disconnected, the
drive might be not EMC compatible.
Do not attempt to install or remove the MOV or EMC
●
screws while power is applied to the drive's input
terminals.

Motor and Equipment Safety

Do not perform any meggar or voltage withstand tests on
any part of the drive or its components. Improper testing may
result in damage.
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.
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.
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.
Before reversing the motor rotation direction, ensure that
this will not cause personal injury or equipment damage.
Make sure that no power correction capacitors are
connected to the drive output or the motor terminals to
prevent drive malfunction and potential damage.
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.
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.
The drive will start up automatically after an input voltage
interruption if the external run command is on.
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.
