Additional instructions and notes
WARNING! Obey these instructions. If you ignore them, injury or death, or damage to the equipment
can occur.
• Drives installed with Raycap Transient Voltage Surge Suppressors (TVSS) connected can be installed to a
symmetrically grounded TNC system. If you install the drive to another system, you must disconnect the
TVSS. Contact factory for other power systems.
• A drive with the internal 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
ACS880 frames R1...R11 EMC filter and ground-to-phase varistor disconnecting instructions
(3AUA0000125152).
WARNING! Do not install a 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 EMC compatibility of the drive is considerably
reduced. See section EMC compatibility and motor cable length in the
frame R6 to R9 (3AUA0000078093),
(3AXD50000034664)
(3AXD50000274444).
• 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 connect EMC filter or disconnect ground-to-phase varistor: TN-S, IT, corner-grounded delta and
midpoint-grounded delta systems in the
disconnecting instructions (3AUA0000125152).
WARNING! Do not install a 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.
• Do not do insulation or voltage withstand tests on the drive or drive modules
If you have a cardiac pacemaker or other electronic medical device, keep away from the area near motor,
drive, and the drive power cabling when the drive is in operation. There are electromagnetic fields present
which can interfere with the function of such devices. This can cause a health hazard.
