6. Measure that the installation is
de-energized.
7. Confirm the multimeter is working by testing
a known source.
• Use a multimeter with an impedance of at
least 1 Mohm.
• Make sure that the voltage between the
drive input power terminals (L1, L2, L3)
and the grounding terminal (PE) is close to
0 V.
8. Install temporary grounding as required by the
local regulations.
If the drive does not operate according to these
steps, refer to the ACH580-31 Hardware
Manual (3AXD5000037066).
Additional instructions and notes
WARNING! Obey these instructions. If you
ignore them, injury or death, or damage to
the equipment can occur.
• A drive with the EMC filter connected can be
installed to a symmetrically grounded TN-S
system. If you install the drive to another
system, check if you must disconnect the
EMC filter. See sections
EMC filter or ground-to-phase varistor:
TN-S, IT, Corner-grounded delta, and
Midpoint-grounded delta systems
15 and Guidelines for installing the drive to a
TT system on page 16.
WARNING! Do not install the drive with
the EMC filter connected to a system
that the filter is not suitable for. This can
cause danger, or damage the drive.
Note: When the internal EMC filter is
disconnected, the drive EMC compatibility is
considerably reduced. See section
Checking the compatibility of EMC filters
with IT (ungrounded), Corner-grounded
delta, Midpoint-grounded delta, and TT
systems on page 14

• A drive with the ground-to-phase varistor
connected can be installed to a
symmetrically grounded TN-S system. If you
install the drive to another system, check if

you must disconnect the varistor. See
sections When to disconnect EMC filter or
ground-to-phase varistor: TN-S, IT,
Corner-grounded delta, and
Midpoint-grounded delta systems
15 and Guidelines for installing the drive to a
TT system on page 16.
WARNING! Do not install the drive with
the ground-to-phase varistor
connected to a system that the varistor is
not suitable for. If you do, the varistor circuit
can be damaged.
• 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.
WARNING! 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 terminals (UDC+, UDC-) 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.
