Important Safety Information
Hazardous High Voltage
WARNING
The components of the power unit of PowerXL DG1 are
live when the AC drive is connected to mains potential.
Coming into contact with this voltage is extremely
dangerous and may cause death or severe injury.
WARNING
The motor terminals U, V, W and the brake resistor
terminals are live when PowerXL DG1 is connected to
mains, even if the motor is not running.
WARNING
After disconnecting the AC drive from the mains, wait
until the indicators on the keypad go out (if no keypad is
attached see the indicators on the cover). Wait 5 more
minutes before doing any work on the connections of
PowerXL DG1. Do not open the cover before this time
has expired. After expiration of this time, use a
measuring equipment to absolutely ensure that no
voltage is present. Always ensure absence of voltage
before starting any electrical work!
WARNING
The control I/O-terminals are isolated from the mains
potential. However, the relay outputs and other I/O-
terminals may have a dangerous control voltage present
even when PowerXL DG1 is disconnected from mains.
WARNING
Before connecting the AC drive to mains, confirm that
the front and cable covers of PowerXL DG1 are closed.
WARNING
During a ramp stop (see the Application Manual), the
motor is still generating voltage to the drive. Therefore,
do not touch the components of the AC drive before the
motor has completely stopped. Wait until the indicators
on the keypad go out (if no keypad is attached see the
indicators on the cover). Wait additional 5 minutes
before starting any work on the drive.
Important Warnings
WARNING
PowerXL DG1 AC drive is meant for fixed installations
only.
WARNING
Do not perform any measurements when the AC drive is
connected to the mains.
WARNING
The ground leakage current of PowerXL DG1 AC drives
exceeds 3.5 mA AC. According to standard EN61800-5-1,
a reinforced protective ground connection must be
ensured.
WARNING
If the AC drive is used as a part of a machine, the machine
manufacturer is responsible for providing the machine
with a supply disconnecting device (EN 60204-1).
WARNING
Only spare parts delivered by Eaton can be used.
WARNING
At power-up, power brake or fault reset the motor will
start immediately if the start signal is active, unless the
pulse control for Start/Stop logic has been selected.
Furthermore, the I/O functionalistic (including start
inputs) may change if parameters, applications or
software are changed. Disconnect, therefore, the motor if
an unexpected start can cause danger.
WARNING
The motor starts automatically after automatic fault
reset if the auto restart function is activated. See the
Application Manual for more detailed information.
WARNING
Prior to measurements on the motor or the motor cable,
disconnect the motor cable from the AC drive.
WARNING
Do not touch the components on the circuit boards.
Static voltage discharge may damage the components.
WARNING
Check that the EMC level of the AC drive corresponds to
the requirements of your supply network.
