ACH580 E-Clipse bypass and packaged drive user manual 7
Installation
Ratings and frame size
For ratings and frame size information refer to the chart in the Ratings
section of the
ACH580-01 Hardware Manual (3AXD50000044839). This section lists technical
specifications, and identifies the drive’s frame size, which is significant, since 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 Type code on page 6.
Also, when using the Ratings tables, note that there are three tables based on the
drive’s “Voltage rating”.
Suitable mounting location
In selecting a suitable mounting location for E-Clipse Bypass configurations, refer to
the Technical data on page 213 in this manual for the appropriate information on:
• Branch circuit protection
• Dimensions and weights
• UL (NEMA) Type 3R, Bx3R-1...Bx3R-4 enclosures are designed to be mounted
on a wall.
Installing the wiring
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 (Hipot 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 in the ACH580-01 Hardware Manual
(3AXD50000044839). The requirements apply to all ACH580 drives. In particular:
• Use separate, metal conduit runs to keep these three classes of wiring apart:
– Input power wiring.
– Motor wiring.
– Control/communications wiring.
• Properly and individually ground the drive, the motor and cable shields.
