6 Supplemental Installation Manual for ACS580-0P
Safety instructions
• Make sure that the voltage between the
drive input power terminals (L1, L2, L3)
and the grounding terminal (PE) is close
to 0 V.
Frames R1…R3: Measure the voltage
between the drive UDC+ terminal and
grounding terminal (PE) with one
multimeter. As there is no UDC- terminal,
measure the voltage between the drive
T1/U terminal and grounding terminal
(PE) with another multimeter. Make sure
that the voltage difference between the
multimeters is close to 0 V.
Frames R4…R9: Measure the voltage
between the drive DC terminals (UDC+
and UDC-) and the grounding terminal
(PE) and make sure that it is close to 0 V.
6. Install temporary grounding as required by
the local regulations.
7. Ask for a permit to work from the person in
control of the electrical installation work.
If the drive does not operate according to these
steps, refer to the
ACS580-01 Hardware
Manual (3AXD50000044794) and Quick Start
Guide (3AXD50000745524)
.
Additional instructions and notes
WARNING! Obey these instructions. If
you ignore them, injury or death, or
damage to the equipment can occur.
• If the drive will be connected on an IT
system (ungrounded or high-resistance-
grounded [over 30 ohms]), make sure
neither the EMC filter nor the ground-to-
phase varistor are connected (metal screws
should not be installed). Connections with
metal screws in these systems can cause
danger or damage. See section
Checking
the compatibility with IT (ungrounded) and
corner-grounded TN systems (North
America) in ACS580 Hardware Manual.
Note: For other systems, connecting the
internal EMC filter will reduce the conducted
emission.
• If the drive will be connected on a corner-
grounded TN system, make sure the EMC
filter is not connected (metal screws should
not be installed). Connections with metal
screws in these systems can cause danger
or damage. See section
Checking the
compatibility with IT (ungrounded) and
corner-grounded TN systems (North
America) in ACS580 Hardware Manual.
Note: For other systems, connecting the
internal EMC filter (using metal screws) will
reduce the conducted emission.
• Use all ELV (extra low voltage) circuits
connected to the drive only within a zone of
equipotential bonding, that is, within a zone
where all simultaneously accessible
conductive parts are electrically connected
to prevent hazardous voltages appearing
between them. You can accomplish this by a
proper factory grounding, that is, make sure
that all simultaneously accessible
conductive parts are grounded to the
protective earth (PE) bus of the building.
• Do not do insulation or voltage withstand
tests on the drive or drive modules.
Note:
• The motor cable terminals of the drive are at
a dangerous voltage when the input power
is on, regardless of whether the motor is
running or not.
• The DC and brake resistor terminals (UDC+,
UDC-, R+ and R-) are at a dangerous
voltage.
• External wiring can supply dangerous
voltages to the terminals of relay outputs
(RO1, RO2 and RO3).
• The Safe torque off function does not
remove the voltage from the main and
auxiliary circuits. The function is not effective
against deliberate sabotage or misuse.
WARNING!
Use a grounding wrist band
when you handle the printed circuit
boards. Do not touch the boards unnecessarily.
The boards contain components sensitive to
electrostatic discharge.
