ACH550-PCR/PDR User’s Manual 3-11
Installation
Ratings and frame size
The charts in the Ratings section on page 1-297 of the ACH550-UH User’s Manual
manual list technical specifications, and identify the drive’s frame size.
Note: Some instructions in this document vary, depending on the drive’s frame size.
To read the Ratings table, you need the “Output current rating” entry from the Type
code (see page 3-10).
Suitable mounting location
For selecting a suitable mounting location for PCR/PDR configurations, refer to:
• The ACH550-UH User’s Manual on page 1-13, and
• The Technical data section on page 3-19 in this manual for the appropriate
information on dimensions and weights
• UL Type 3R, PX3R-1...PX3R-4 enclosures are designed to be mounted on a wall.
Mounting these 3R enclosures on an open rack system requires the use of the
supplied 3R enclosure back plates to maintain 3R integrity.
Installing the wiring (supplement to ACH550-UH User’s Manual)
WARNING!
• Metal shavings or debris in the enclosure can damage electrical equipment and
create a hazardous condition. Where parts, such as conduit plates require cutting
or drilling, first remove the part. If that is not practical, cover nearby electrical
components to protect them from all shavings or debris.
• Do not connect or disconnect input or output power wiring, or control wires, when
power is applied.
• Never connect line voltage to drive output Terminals T1, T2, and T3.
• Do not make any voltage tolerance tests (Hi Pot or Megger) on any part of the
unit. Disconnect motor wires before taking any measurements in the motor or
motor wires.
• Make sure that power factor correction capacitors are not connected between the
drive and the motor.
Wiring requirements
Refer to the Wiring requirements section on page 1-18 in the ACH550-UH User’s
Manual. The requirements apply to all ACH550 drives. In particular:
• Use separate, metal conduit runs for the following different classes of wiring:
– Input power wiring.
– Motor wiring.
– Control/communications wiring.
• Properly and individually ground the drive, the motor and cable shields.
